I’m a space junkie. I grew up watching the Space Race between the US and USSR. I remember the first US manned space flight – Alan Shepard’s 15 minute sub-orbital jaunt off the coast of Florida. I bought a vinyl recording of the air-to-ground communications and listened to it enough times to be able to recite the capsule- to-Canaveral communications from memory. The deaths of my heroes on Apollo I, Challenger, and Columbia (as well as of several Soviet cosmonauts) were like a death in the family. I thrived on the successes of Mercury, Gemini, Skylab, Apollo, Mir, the International Space Station, and the Shuttle. When I started my career in the summer of 1969, one of my first purchases was a television set so I could watch the miracle of Neil Armstrong’s footsteps on the moon. While I didn’t work directly on any of the space programs, during my career I was fortunate to work to support the Atlas, Titan, Landsat, Shuttle, ISS, and several classified space programs. I’ve had “behind the scenes” tours of the Johnson Space Center (that’s me on the left in the photo with Dr. Segun Thomas at JSC in front of a huge environmental test chamber) and the Kennedy Space Center, highlighted by the thrill of piloting the Space Shuttle simulator to a not-so-perfect landing on the KSC runway. I’ve been fortunate to work with several former astronauts – all as fiercely intelligent as they are brave.
After the splashdown of Apollo 17 in 1972, the buzz of the manned space program was somewhat abated. We were at a crossroads. We met President Kennedy’s goal of going to the moon and returning safely by the end of the decade, and repeated it five more times. (And by the way, all of this was done using computer technology that was much less powerful than the iPhone I carry in my pocket). We bit our nails until the ill-fated Apollo 13 came home. The “reusable” Space Shuttle program was started – albeit without a clear mission. We had some subsequent wonderful and priceless scientific successes in unmanned space exploration through the Hubble Space Telescope (which couldn’t have been successful without the several manned repair and upgrade missions), the never-say-die Spirit and Opportunity exploration of Mars, and numerous deep space probes that have travelled into the deep reaches of the Solar System.
Now, we are at another crossroads. The Shuttle program is winding down, with five more flights to go. Nothing generates as much excitement as manned space flight. Is it expensive? Sure. Is it worth it in terms of risk and dollars? Certainly. Those who argue that we can learn as much about the planets by sending unmanned probes are right, but manned space flight provides much more than excitement and national pride. Advances in medicine, materials, energy, and other fields are direct results of the manned space program.
So where do we go from here? President Obama cancelled the Constellation program which would have built the boosters and capsules to return us to the moon. (Full disclosure: I am retired from Lockheed Martin which had a big chunk of the Constellation program). Instead, NASA will spend $6 billion to jump start private companies to develop and operate vehicles that will ferry civilian astronauts to the International Space Station.
While the cancellation of the Constellation program was the right thing to do, our experience with the privatization of government services is unblemished by success. Competition is a good thing, but operating the space program as a “for profit” enterprise will result in duplication of effort, compromise safety, and reduce the ancillary benefits that we have enjoyed from NASA’s research and development. We will lose the programs that NASA has run with schools and universities that encourage students to study math and science, and we will continue to abdicate our leadership in these areas to China and India. Manned space flight is a risky business, and it is yet to be seen whether private companies will be willing to assume those risks. Sure, there will be government subsidies, but as we have seen in the banking business, subsidies without control lead to a small number of very rich people with no upside for the taxpayer.
There is a better way – and we have irrefutable evidence that it works.
Let’s set a goal of a manned mission to Mars. The Red Planet has been an object of human wonderment since the first cave man marveled at this oddly colored moving star in the sky. But let’s not do it alone. Make it a goal of humankind to establish a presence on Mars by 2025 and continue the mission spearheaded by our astronauts, cosmonauts, and taikonauts. We need to partner with Russia, China, Japan, India, the European Space Agency, and the rest of the world to make a Mars mission a global goal. We have shown that we can partner with our fellow humans on the International Space Station – let’s take it to the next step and expand those partnership goals to work together to go to Mars. Not only will this allow us to share the expense and rewards, but it also will be a giant leap to bring mankind together for a common and difficult goal.


Uganda Airlines is aiming to bolster its crew numbers by doubling its current capacity in order to tackle flight delays and expand into new routes. David Kaweesa, the Director of Flight Operations at Uganda Airlines, emphasized the airline’s need to increase its crew to meet targeted flights and route plans.
Currently, Uganda Airlines operates with 13 pairs of first officers and 13 pairs of captains, which falls short of the required capacity to expand regional flights and introduce new routes. To meet their flight and revenue targets, the airline aims to boost crew numbers to at least 24 pairs of captains and 24 pairs of first officers.
In efforts to comply with regulatory requirements and ensure crew members’ well-being, Uganda Airlines has reduced flight frequencies on certain routes such as Nairobi and Juba. Jennifer Bamuturaki, the CEO of Uganda Airlines, highlighted the importance of adhering to regulations and maintaining crew rest periods to prevent overworking.
Flight delays and cancellations have been attributed to the airline’s struggle to maintain safe operating margins due to crew shortages. Despite recruiting efforts, securing sufficient crew members has proven challenging, with only four successful applicants out of 67 for first captain positions.
The shortage in crew numbers has led to delays in Uganda Airlines’ expansion plans, including launches into new routes like London, Guangzhou, Jeddah Riyad, Abuja, and Lusaka. However, the airline remains optimistic about securing funding in the upcoming financial year to support operations and enhance competitiveness.


Back in February and March 2020, aerospace and defense stocks were in freefall. Suddenly, instead of symbolizing the speed and connectivity of the modern economy, the whole of the aviation industry ground to a halt. Even the military was put in a bind as soldiers often live and work in close quarters. The advent of a COVID vaccine further deepened the divide as some in the Armed Forces chose to be discharged rather than be inoculated.
Likewise, many seething geopolitical rivalries faded into the backdrop as the international community focused on combating the threat of the coronavirus. Now that much of the world has returned to some semblance of normal, air travel has picked up dramatically from its 2020 lows, according to data from the U.S. Bureau of Transportation Statistics.
Also, prior geopolitical rivalries flared up again, which incentivizes military-related spending. Below are the best aerospace and defense company stocks to watch out for this year as you invest.
Quick Look at the Best Aerospace and Defese Stocks:
- Lockheed Martin
- General Dynamics
Thanks to the intersection of national security interests and the drive for economic competition, the best aerospace and defense stocks historically provide an excellent arena for buy-and-hold investors to grow their portfolios.
Unfortunately, the COVID-19 crisis proved that very few sectors could avoid the initial volatility associated with a once-in-a-century pandemic. At the same time, defense contracts never stop, and these contracts have a massive impact on the stock market. As defense contracts are awarded, defense firms see increases in both cash flow and stock prices. This means that aerospace stocks and defense companies are constantly changing in valuation. Their receivables, while massive, are still subject to change. Government contracts could go to the competition and defense spending could be reallocated at any time.
Plus, Wall Street can see strength in a particular industry, be it the technology side or the manufacturing side. Investors know how much government spending is expected from these firms, and that often impacts everyone’s trading strategy.
Nevertheless, the U.S. and the global community came together to manufacture and distribute a vaccine in record time. With a return to normalcy comes economic opportunities, along with a resurgence of old rivalries, both boding cynically well for aerospace and defense stocks.
Overview: Aerospace and Defense Stock
As one of the most competitive and lucrative market segments, aerospace and defense stocks fundamentally offer investors a double dose of profitability potential. First, the aerospace industry transformed the 20th century, enabling people to travel great distances at unprecedented speed. As we progress along the technological spectrum this century, aerospace firms are aiming even higher. For instance, experts believe that space tourism will become a $1.57 billion industry by 2028. This doesn’t even count military spending, which is always quite high.
Second, investors can readily bank on the relevance of the defense component of the aerospace market. No matter how humanity progresses, the conflict appears inevitable — and there may be plenty of it. As the world’s sole superpower, the U.S. has a unique responsibility to project power and deter adversarial or belligerent actors from undermining American interests and that of U.S. allies.
Further, because of a transition in power in Washington, D.C., and the stark shift in leadership culture, a few nations appear to be testing the Biden administration. Therefore, it’s possible that defense spending could increase to counteract such high-level shenanigans, which may bode well for aerospace and defense stocks. Additionally, Deloitte reports that U.S. allies such as Japan are beefing up their security profile, potentially providing additional revenue streams for American defense contractors, especially as the defense budget continues to rise with inflation.
Finally, the COVID-19 crisis initially imposed what appeared to be crippling volatility among aerospace and defense stocks. Logically, with billions of people around the world practically forced into quarantine, airplanes sat parked on tarmacs. Not only was that devastating for commercial airliners, but the aerospace industry also suffered steep losses in product and service revenues.
However, with the return of consumers wanting to make up for lost time, the defense sector could see a revival. Contract awards to firms like Northrup Grumman and United Technologies can easily drive up the gross domestic product.
Best Online Brokers for Aerospace and Defense Stock
Though you may find a few exceptions to the rule, aerospace and defense stocks tend to be well-capitalized and deeply established blue-chip names. Given the complex nature of the business, along with its mission-critical profile, the industry features a high barrier to entry. Therefore, you usually don’t have to worry about an upstart competitor ruining your portfolio.
Further, the tough-to-crack aerospace sector enables you the freedom to choose your online broker based on your lifestyle and preferences. With the best aerospace and defense stocks on this list mostly being household names, any brokerage will carry their equity units. To help you decide, below are the best online brokers for the aerospace and defense industry.
Features to Look for in Aerospace and Defense Stock
- Balanced pipeline: When assessing aerospace and defense stocks, the latter portion invariably draws the most attraction — fighter jets offer more pizzazz than commercial jetliners. Nevertheless, the most successful companies in this sector have found a healthy balance between commercial and military applications. This balance may become even more important in the future as defense budgets could find themselves under pressure from fiscal and political headwinds.
- Track record: In the defense industry, no greater honor exists than repeat business. If particular weapons and security systems work well, military and government agencies will continue requesting them. Similarly, if commercial aerospace entities consistently satisfy consumers and clients, they too will provide repeat business. Therefore, when figuring out which aerospace and defense stocks to buy, consider a heavier allocation toward companies that have a strong track record and brand reputation.
- Robust financials: Although robust financials is an attribute that investors should consider for any equity sector category, it’s particularly important for aerospace and defense stocks. For one thing, this market subsegment is capital-intensive. Second, no one knows for sure how the COVID-19 pandemic will ultimately play out. For example, consumer fears could linger, which may pose challenges on the commercial side. But companies with strong balance sheets can ride out the pain longer than others.
- Obvious connections to the military: When you invest in companies like Raytheon Technologies, Lockheed Martin Corporation (which is developing the F35 fighter jet), Collins Aerospace(a subsidiary of Raytheon), Archer Aviation (which is developing air taxis that could prove useful in forward areas), Rocket Lab USA, Northrup Grumman Corporation (which develops the B-2 and B-21), etc., you can see the obvious connection to military spending.
- Strong supply chain: When you invest in a defense business, supply chain issues are common. Remember, everything from air mobility to a random equipment manufacturer can slow a big contract. Airplane production takes time, and while contract announcements are exciting, there’s never an end-date on those announcements. Keep your eye on manufacturers of aircraft components like Spirit Aerosystems, stock returns across the sector and even what hedge fund holders are doing so that get the “big picture”.
Fly the Friendly (and Unfriendly) Skies for Serious Gains
In many ways, aerospace and defense stocks represent an intriguing contradiction. Invariably, the defense component draws much controversy because of its underlying product’s deadly effectiveness. On the other hand, military innovations have the propensity to improve civilian applications.
From the investor’s point of view, aerospace and defense stocks offer a 2-for-1 approach. During bull markets, the aerospace component enjoys substantial demand as people travel around the world. In times of geopolitical tension, the defense angle can hedge an investor’s portfolio against certain risks. Therefore, this sector is always worth consideration.

When Betty Jane came to town last June she made a lifetime fantasy come true. My fantasy was to fly in a WWII fighter, such as a Vought F4U Corsair, P38 Lockheed Lightning or a North American P51 Mustang. The P51 was the most successful fighter in WWII with over 4000 German aircraft kills. The Betty Jane is a P51C that has been modified as the only P51 with a tandem cockpit with duel controls.
I have been reviewing just when and how this fantasy all got started.
As a youngster in 1941 we had family friends who's son John Forrest Luma had enlisted in the Royal Canadian Air Force ( RCAF) that summer. John earned the nickname of "Lou" in the RCAF. This was all before Pearl Harbor, however Canada being part of the British Commonwealth was already at war with Germany. Our family would occasionally receive Victory Mail from Lou from Europe.
The V-mail was highly censored so no one here knew where in Europe he was but we did know he was flying Mosquito Fighter Bombers. The Saturday Evening Post would occasionally have a center section article featuring various airplane squadrons. When I was about ten years the Post featured the Mosquito Bomber. I don't remember the details in the article, but I do remember a good portion
of one page was about the pilot John Forrest Luma.
In any case as a young kid, to me the pilots and their planes they flew were heroic and Lou was the best. I had picked a good hero for John Forrest Luma won both the American Distinguished Flying Cross (DFC) and the British DFC. I cut out lots pictures
of military aircraft and tried to draw pictures of them. I developed an ear for some aircraft that flew over the Northend -
B17's and the very unique sound of a P38. By the time I was ten I thought the greatest thing that one could do was to fly a single engine fighter and some day I would fly in one.
On June 26, 2010 Patrick McGarry, Check Captain Flight Operations of US Airways and I took off from Boeing field in the Betty Jane. As Captain McGarry was not real familiar with our part of the world I suggested the Skykomish valley up around Mt. Index. We flew north over Puget sound along the shoreline to Everett then turned east following the Skykomish river. When we flew over Mt. Index the Captain turned me loose. As I hadn't had a joy stick in my hand since the early 60's I at first just tried tight turns keeping the nose on the horizon. Part of the reason for suggesting this area was I wanted to fly over the mountains where
I have hiked in the last sixty five years. I wanted to see Blanco Lake from the air so I headed for Index. Once spotting the
Lake and the vertical drop of Troublesome Creek it was time to see how coordinated this old man might still be. The wingovers, victory rolls, and barrel rolls were far from precision but bloody damn fun. It was time to head home so Captain McGarry took over. He shot down a few clouds then did a tight roll into a steep diving descent. We wrapped around a sharp peak using it
like a pylon about thirty feet off our right wing as we dropped into the Snoqualmie River basin. We did a circle around Snoqualmie Falls. Captain McGarry wanted to check out the sights and I remembered I had a pocket camera with me. We returned to Boeing Field where we both agreed it was a good flight.
So it was a special day. For two years now my back has failed me first for skiing then a year later for hiking. To have a day where I felt a real adrenaline rush made me feel like I shook off a little rust. Not only did I get to fly in a P51 Mustang,
I got 1.2 hours as duel pilot in my log book. How about that song, "Your dreams can come true. It can happen to you, if you
are young at heart." Yes indeed I must be a kid again.
Note: When the United States joined the war Mr. Luma was brought into the United States Army Air Force, however because of circumstances he remained with the Canadians for an extended period. If interested in the story of John Forrest Luma, you may want to check out the following two websites:

Lockheed Martin has been awarded a contract for Trident II D5 missile deployed system support.
The deal, announced Tuesday by the Department of Defense, is valued at more than $28.7 million under a cost-plus-fixed-fee, which is a modification on a previous award.
The contract calls for support services for the Trident II D5 missile deployed system.
The UGM-133A Trident II, or Trident D5, is the latest generation of submarine-launched ballistic missiles.
The work will occur in California, Florida and Colorado, and other locations, according to the Pentagon, and is expected to be completed in September 2020.
More than $28.7 million will be obligated to Lockheed Martin at the time of award, with more than $1.953 million expiring at the end of the current fiscal year.


Right now there are six International Space Station Astronauts 250 miles above the earth, free-floating way up there above us. What they don’t know is they’re in the most fabulous treat. The SpaceX Falcon Rocket is on its way to space and apart from its usual supplies of food, clean underwear, and loo paper, it’s carrying a very precious cargo.
Ice cream! There are thirty small cups of Ice Cream for the astronauts, in all delicious flavors. This means they each get to have five ice creams unless of course one of them doesn’t want!
ICE CREAM FOR ASTRONAUTS
To be in space is a very hard work. Sure, it is a dream for anyone to become an astronaut but once up there, it’s tough. Apart from the fact that you float through the air for months on end because of gravity, everything is tricky, from eating to dressing to breathing, and daily life does need some respite. NASA wants to make life as easy as possible, or pleasurable where possible, and this includes ice cream for astronauts.
The cargo that is on its way right now, weighs a total of 6400 pounds. The ice cream is clearly not a large part of this cargo, probably not weighing more than a couple of pounds. Apart from all the practical stuff, the rocket is carrying hardware for the Space Station, a whole lot of live mice as well as many scientific experiments.
Here is the launch of the Rocket carrying Ice Cream for Astronauts:
The astronauts are trying to grow crystals up in space in the hope of finding new treatments for Parkinson’s disease, funded by Michael J. Fox.
Astronauts do important scientific research up there in Space. So is Ice Cream for astronauts a necessity?
Probably not at all, but it is right up there with the fruit bars or small slabs of chocolate. We all love treats and especially when your treats are delivered by a rocket to space. And especially when they taste like they are supposed to and not like cardboard. Haven’t you heard this ice cream is really good?
The delivery will arrive sometime Wednesday and any delivery that the astronauts get is welcomed with delight. There will be live footage by NASA once the docking and delivery are safely complete. We hope the ice cream for astronauts is a huge success and we wish them Bon Appetite.


The International Space Station (ISS) prepared yesterday to carry out a space debris evasion maneuver in order to prevent it from spreading through space.
Roscosmos, the Russian space agency, has confirmed this through a statement in which it reports this decision, because the distance between the ISS and the space debris was above 600 meters .
This action was carried out yesterday at 9:15 p.m. Spanish time, carrying out a maneuver that consisted of moving the modular station away from space debris . According to Roscosmos, the piece belonged to the Chinese meteorological satellite ‘Fengyun-1C’.
The Cnet medium explains that China destroyed this satellite in January 2007 because it was part of a test of anti-satellite missiles , causing its pieces to spread throughout space until reaching a point where it was impossible to identify them due to their miniscule size.
To carry out this maneuver, the International Space Station has used the ‘Progress MS-18’ refueling ship, as it is incorporated into its structure and has orientation and coupling motors that turn on in just over six minutes. Consequently, it was possible to increase the altitude of the space station by 1,240 meters to place it in an operational orbit, about 421 kilometers above the Earth .
When the system completes the tests, it will self-destruct.
A spokesman for NASA claimed to Gizmodo that “the likelihood of impact and risk to the International Space Station is very low, the maneuver is standard and does not require the crew to take any specific action.”
Seeing this type of action is quite common because it avoids collisions, and the chances are very high that space debris could damage the infrastructure of the ISS. On the other hand, this type of junk is becoming a trend and is getting worse over time as satellites enter low Earth orbit .

I can remember two occasions in my lifetime that could have resulted in my early demise. I’ve had other scary incidents, such as red-light runners passing within inches of my car, but they are less memorable.
My first frightening event occurred in 1967 (during a summer trainee program in Colorado) when a burst appendix put me in the hospital for 15 days. The situation was so dire that my parents were called and told to fly immediately (from Pennsylvania) to Colorado; Mom had never been on an airplane. The second incident occurred two years later. I can now laugh at what was nothing more than a harrowing incident. At the time, however, it seemed serious indeed.
In 1968, I began work for the Navy Weather Research Facility in Norfolk, Virginia, my first job after graduating from Penn State. A year later, I had the opportunity to participate in Project Stormfury, a government experiment to seed hurricanes. Without going into technical detail, the goal was to decrease hurricane winds to minimize storm damage. (Afterward, it was determined that the effects from the seeding were far too weak.)
I traveled to the Roosevelt Roads Naval Station in Puerto Rico where I was trained to be a Radar Advisor. Basically, that meant that I took pictures of the radar screen on the Hurricane Hunter WC-121 aircraft, a four engine propeller-driven plane. This aircraft was a “weather” version of the Navy and Air Force early warning and control radar surveillance aircraft, the EC-121; it featured two powerful radars.
I’ve forgotten how many times we flew during my stay. But I do remember one mission to investigate a tropical disturbance. You must remember that back then we did not have continuous satellite imagery like we have now, and “Hurricane Hunters” were essential observational tools. Flying at around 250 MPH, our aircraft had a range of over 4000 miles. As I recall, this mission was in the 8-10 hours in length.
Long story short, we flew some 1000 miles only to discover that the disturbance had weakened, with not much to look at or take radar pictures of. So, we headed home.
I may have been the first person on the aircraft to notice the smoke. Soon everyone knew, especially the people flying the plane. Fire on an aircraft is not a good thing, and perhaps more worrisome on one first put into service in 1954. From our 10,000-foot cruising altitude, we immediately descended to our “ditching” altitude, 1000 or 500 feet as I recall. I remember thinking that landing in the water some 1000 miles from my hotel room would make me late for dinner. Further, my swimming skills were minimal at best. To compound my fears, one crew member told me that there had never been a successful ditching of that particular aircraft. I couldn’t help but wonder what his definition of “successful” was.
At that point, excitement reigned. One of the pilots rushed back into the aircraft and began tearing away sections of the fuselage, revealing various electrical panels, trying to locate the source of the smoke. Meanwhile, the smoke was still there.
After maybe fifteen minutes of panic (on my part), it was over as quickly as it began. The smoke abated, we returned to our 10,000-foot altitude, and flew home uneventfully. To my knowledge the source of the smoke was never determined.
Please write and let me know about your most memorable close call.

I read with horror the news that a FLYBE plane from Belfast to Liverpool had to make an emergency landing shortly after taking off from Belfast City Airport. The aircraft was diverted to Belfast International Airport and landed with one engine out.
I'm telling you, forget the RA; FLYBE want to be stood down!
I travelled on that exact same route with FLYBE in April when we attended the NUS conference in Blackpool and it was like flying in a large tin can with match sticks propelling us.
Scared the f****** shit out of us coming back
Up and down, left and right!
I know the flights are cheap but it is worth paying extra for some things in life
e.g. your life


Charter jet membership offers multiple benefits over regular flying and scheduled aviation. The top benefits include privacy, efficiency, and flexibility. Better still, chartering private jets is not just for celebrities, executives, and corporates. Families and tour groups can also use private charter jets for vacations to get from one place to another. With a private jet charter, you have the flexibility to plan your stay trip depending on your needs and leave when you feel like it. It also allows you to select the airports you want to use, the amenities you want on the plane, and the plane you want to travel with.
Things to Consider when Choosing a Charter Jet Membership
If you are hunting for a charter jet membership, you will find a wide range of models on the market today. But before signing on the dotted line, it is essential to do your due diligence and know the best model for you and your needs. Here are some of the things you should look for:
Charter airlines are expected to have some of the best pilots in the industry. Therefore, you should ensure that the pilots have undergone intensive training and have the proper certifications and licenses for the job. They should also have at least five years of experience, meaning they can handle all potential issues with the ultimate professionalism. Besides the pilots, you should also ensure that the flight attendants and other crews have the necessary skills.
Fleet Size and Diversity
Charter airlines often have different aircraft in their fleet. The planes vary, and each has its purpose. That is why it is essential to explore all the various memberships and choose the diverse aircraft to meet your needs.
Reputation is vital in life, and charter jet membership is no different. You should only go for a charter airline with a solid track record and reputation. The airline should also have a good safety record. You can do this by checking the reviews and testimonials on the airline’s website. You can also talk to the people within your circle to know their chosen membership and why. In this case, you can select the airline with the most recommendations.
Safety and Maintenance Strategies
Safety is one of the most critical things in charter flights. That’s why you should make sure to inquire about the protocols in place for the aircraft and the pilots. A good airline will follow the FAA regulations and ensure that the aircraft are maintained to the highest possible levels. The aircraft should be inspected routinely to ensure they are safe for use.
Before signing your charter jet membership, you should make sure that you understand the fees associated with every charter. Most charters charge an initiation and an annual fee, but it is crucial to inquire about any extra charges.
Charter airlines are an ideal way to travel. They offer a luxurious travel experience that might not be possible with standard airlines. For the most reliable charter jet membership, Hera Flight has you covered. We are a charter airline committed to providing diverse membership options to suit everyone’s needs and budget.


Some of my pictures taken at KSC for the Endeavour/STS-134 launch a few weeks ago. Seth Green (centre photo) was one of the attendees at the Tweetup.
NASA is hosting a two-day Tweetup for 150 of its Twitter followers on 7-8 July, at Kennedy Space Center in Florida. Space Shuttle Atlantis is scheduled to make its final flight at 11:40am on July 8 – the very last space shuttle launch, ever.
What's a Tweetup?
It's basically a gathering of people who use the social networking site, Twitter. But for lucky folk who attend NASA's Tweetup, it's an opportunity to meet and mingle with Astronauts, NASA personnel and experience one of the greatest spectacles from the closest viewing spot to the launch pad.
NASA held a Tweetup for the STS-134 launch, and while I didn't get to check it out first-hand, I managed to talk to a few of the Tweeps attending, and they had an absolute blast. They had a pre-planned schedule of talks from NASA employees and astronauts, were given tours of the various facilities, etc. And of course the got to tweet their experiences for the rest of the world to share.
All New Zealander Tweeps should apply!
Given my own experiences, I cannot impress enough that any New Zealand user of twitter, with even an passing interest in space should apply. You need to pay for flights and accommodation, but this is the last ever shuttle launch, and so you don't want to miss out. And you get so much more than just a launch - backstage viewing of NASA's Kennedy Space Center, etc.
I've just spent 3.5 weeks at KSC for STS-134, and am seriously considering going back to see the final launch!


|IAF MiG-21 Fighter Aircraft Crashes|
An Indian Air Force MiG-21 fighter aircraft crashed near Moga in Punjab late last night. The pilot, Squadron Leader Abhinav Choudhary sustained fatal injuries. "There was an aircraft accident last night involving a Bison aircraft of the IAF in the western sector. The pilot, Sqn Ldr Abhinav Choudhary, sustained fatal injuries," the Indian Air Forces said on Twitter.
“IAF condoles the tragic loss and stands firmly with the bereaved family,” the tweet further stated. A court of inquiry has been ordered to ascertain the cause of the accident, IAF said.
This is the third crash of a MiG-21 aircraft this year. In March, a Group Captain of the IAF was killed in an accident involving a MiG-21 Bison aircraft at an airbase in central India.


While most immediately think of NASA and astronauts, civil space accounts for just a third of all government space activities in the U.S. Satellites are critical infrastructure for the U.S. Department of Defense (DoD), and investing in technologies to support that infrastructure is one of the catalysts behind the launch of the United States Space Force, USSF. As such, opportunities with government funding for development and testing has never been higher for Atomos—in civil or defense.
Satellites support nearly every DoD operation. From communication, to navigation, to GPS, to Earth observation, space provides valuable information to decision makers. When satellites that are able to perform these tasks are in the wrong orbital position, unable to cover an emerging conflict zone, the ability to communicate, gather intelligence, or have reliable navigation is compromised. To fill all potential gaps, the DoD would need to greatly increase their satellite fleets. Their budget may have more zeros, but even the DoD doesn’t have infinite resources. They, too, need lower costs to place satellites in space, particularly beyond low Earth orbit (LEO), which is strategically important as LEO has vulnerabilities. As is true with our commercial customers, placing satellites in higher orbits costs considerably more. This cost-benefit trade compromises the performance of DoD satellite systems.
“Virtually every major U.S. military space system is facing a planned upgrade or replacement over the coming decade, at an estimated cost of some $60 billion… All of these options are competing for scarce resources within the Air Force budget, and hard choices will have to be made and impediments removed if those options are to be realized .”
Atomos’ Orbital Transfer Vehicles (OTVs) address these shortcomings through launch cost reduction, increased launch flexibility, and our unique ability to rendezvous with and relocate satellites already on-orbit. Atomos provided and received input from various DoD stakeholders on how our commercial solution fill various mission needs. In the last few months, we’ve received a Letter of Support from the U.S. Space Force, participated in the U.S. Airforce’s National Security Launch Architecture study, proceeded to the second round for a Defense Innovation Unit proposal to develop an OTV prototype, and spoke to Air Force units in the U.S. during our Phase I AFWERX SBIR Contract, which culminated with an Memorandum of Understanding with the Space Development Agency.
Beyond in-space transportation, Atomos’ long-term goal of space nuclear has increased interest at the DoD, particularly with DARPA’s DRACO program. We’ve had several meetings with the program director on how Atomos can play a part in this large initiative.
Atomos’ power and propulsion technologies is an obvious solution for deep space and exploration mission for NASA, but our systems also solve NASA’s needs nearer to Earth. Similar to the Commercial Resupply Services (CRS) that enable commercial companies to fly cargo to the International Space Station , NASA wants commercial companies to fly cargo to the future Lunar Gatway This $7B program, which seeks repeated cargo delivery of 4,400kg to the Gateway in lunar orbit, is a perfect fit for Atomos’ Proton and Neutron OTVs .
Like the DoD, NASA is giving space nuclear a renewed look and renewed funding. The NASA budget, issued by The White House, allocated $100M to space nuclear—now its own line item. This amount increases to $257M by 2025. As stated in the Congressional Justification:
The foundation for these capabilities is in focused technology development across four major elements:
(1) nuclear fission power to establish electric power reactor designs to support Artemis; and within Nuclear Propulsion:
(2) nuclear fuel and reactor development,
(3) nuclear fission power and propulsion study assessments, and
(4) nuclear fission propulsion subsystem development.
Working with the U.S. Government
Agencies are shaping procurement around existing or planned commercial products and services, reducing the need for commercial companies to tailor products for a government buyer. Incumbent, Prime Contractors aren’t the only ones winning contracts now. From 2000 to 2018, entrepreneurial space companies received $7.2B in public funding. The U.S. Government, and the DoD especially, realize that reinventing the wheel is expensive and see that it’s more cost-effective to find existing or emerging solutions that can solve their problems from non-traditional suppliers.
Funding cycles driven by politics can add uncertainty and deters reliance public funding, but a balanced approach of commercial and government markets diversifies the risk of both and increases our chance of success. There are many examples of how successful this has been, but most notable among entrepreneurial aerospace companies is SpaceX. NASA funded a significant portion of SpaceX’s Dragon Capsule and Falcon 9 development and SpaceX continues to earn nearly half of their launch revenue from the U.S. government .
We are cautious to pursue opportunities that closely align with our commercial development plans. In these early years, it’s important to avoid distractions and remain focused. But if there is money on the table, we’ll certainly evaluate the risks and benefits. We’re always looking for interesting opportunities that provide dilutive capital to move the mission forward. Here are some upcoming opportunities we’re exploring.

What is paragliding? Paragliding is the most accessible flight sport ,in France this is called 'parapente'. Floating from one thermal to another we can, with enough experience, spend hours above the earth and travel large distances (distance record to date: 500 km!) To "paraglide" we use a parachute, but a very special. You sit comfortably in a harness and using only two control lines, you stear where you go. All your gear fits in a backpack: all you need is one mountain to start from. In the absence of mountains in the Flemish (Northern) part of Belgium, we start with a winch, a 1000 meters cable pulls you like a glider into the air. At the highest point you disconnect the cable and then the world is yours! Air sports are known to many people as expensive to practice hard and to learn. But that is not true for paragliding. Paragliding is the most accessible of all air sports and very affordable.
The charm of paragliding is the simplicity. Although the achievements of 'our' wings get better every year, we're still capable of putting a full equipment in a single backpack. The first paragliders in the 80's flew in a few minutes from the top to the valley, but with the current material experienced pilots have flights of several hours are earlier norm than exception and there are record distances of over 400 km (2006) non-stop flying . It's also possible to fly by two, one pilot and one passenger, this is called biplace paragliding.
Who can do this wonderful sport? Almost anyone can learn to fly a paraglider. The minimum age of 14 years is required for BVVF affiliated schools. You do not need a very good condition and paragliding is definitely not weight training, though the first days of physical training are fairly intense. Both women and men practice paragliding with heart and passion, and both are represented in our club. Although women are still in the minority, however, their number is still growing. Young people learn about the sport in general a little easier, but people over 50 with no experience can successfully complete the training.
The paragliding equipment Every experienced pilot has his own opinion on what should include a complete equipment. If you walk to a peak that climbs 2000 meters above the valley, you can imagine you have other demands on your equipment (weight) than when the ski lift or the winch is pulling you up.
A 'basic' equipment usually looks like this: -The flying device (paraglider or wing) The wing allows us to continue to soar. On the ground it looks like a pile of fabric and lines, but in the sky is the device, filled with air, creating enough lift to keep us away from the ground. - The harness (the seat) The first armor seemed to be nothing more than a climbing harnesses, but these days it are comfortable seats with storage compartments, back protection and a place for the reserve parachute. - The reserve parachute For the (rare fortunately) situation that the screen does not fly anymore, we have a reserve parachute with us. It can be opened in seconds and allows us to safely reach the ground. Many pilots never use the reserve in their entire flying career, but still carry it always with them. - Tools An altimeter is usually required. A radio is essential during training, but also after the training is the radio for contact with other pilots and people on the ground. A compass or gps is handy when you are flying XC (cross distances). - Clothes Helmet and gloves are required for protection. Decent shoes are preffered to protect you on rough landings.
This is all you need to fly for hours. Some pilots have a special fly suite, a GPS, a compass, food, first aid kit, etc. with them. Pilots come in all shapes and sizes, from minimalism to gadget freaks and there is room for everyone in the free world of paragliding.

¥ how a rocket is constructed so that it is stable, has minimum drag and maximum momentum ¥ how the studies of physics and rocketry are related, specifically newtonõ s three laws of motion, the four forces that operate on objects moving through air and how ener gy is formed. Rocket launch physics explained rocket during launch in terms of the: – law of conservation of momentum how rocket engines work - duration: 4:41. Physics of rocket flight in order to understand the behaviour of rockets it is necessary to have a basic grounding in physics, in particular some of the principles of statics and dynamics this section looks at the relationships between distance, velocity, acceleration, force, work, impulse, energy and power. Newton's third law states that every action has an equal and opposite reaction in a rocket, burning fuel creates a push on the front of the rocket pushing it forward this creates an equal and opposite push on the exhaust gas backwards.
Rocket principles a rocket in its simplest form is a chamber enclosing a gas under pressure a small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction a good example of this is a balloon. A rocket blasting off the launch pad changes from a state of rest to a state of motion the third term important to understanding this law is unbalanced force if you hold a ball in your hand and keep it still, the ball is at rest.
Rocket physics, in the most basic sense, involves the application of newton's laws to a system with variable mass a rocket has variable mass because its mass decreases over time, as a result of its fuel (propellant) burning off.
Rocket physics plays a crucial role in the modern world from launching satellites into orbit to testing intercontinental ballistic missiles (icbms), principles of rocket mechanics have innumerable applications the guidance system has two main roles during the launch of a rocket: to provide stability for the rocket, and to control the. Ask an explainer q: how does a rocket relate to newton's three laws of motion a: like all objects, rockets are governed by newton's laws of motion the first law describes how an object acts when no force is acting upon it so, rockets stay still until a force is applied to move them likewise, once they're in motion, they won't stop until a.
Thrust of a rocket rocket thrust results from the high speed ejection of material and does not require any medium to push against conservation of momentum dictates that if material is ejected backward, the forward momentum of the remaining rocket must increase since an isolated system cannot change its net momentum.
Force (terminal velocity) at engine burnout, gravity and drag work to slow the rocket down when all upwards (vertical) velocity is lost, gravity causes the rocket to accelerate downwards, building velocity until either the recovery system deploys, terminal velocity is reached or the rocket impacts the ground. A rocket obtains thrust by the principle of action and reaction (newton's third law) as the rocket propellant ignites, it experiences a very large acceleration and exits the back of the rocket (as exhaust) at a very high velocity this backwards acceleration of the exhaust exerts a push force on the rocket in the opposite direction, causing the rocket to accelerate forward this is the essential principle behind the physics of rockets, and how rockets work.
The rocket mass m decreases dramatically during flight because most of the rocket is fuel to begin with, so that acceleration increases continuously, reaching a maximum just before the fuel is exhausted. When a rocket is launched there is an upthrust which is provided by the combustion of its engine however, during the launch a rocket initially remains still then gradually lifts off with increasing speed does this mean that the upthrust of the rocket increases gradually over the initial stages of.
For an object like a rocket, with a large change in mass during the flight, we must use the more accurate definition of the second law associated with the change in momentum for an external applied force, the change in velocity depends on the mass of the object. The guidance system has two main roles during the launch of a rocket: to provide stability for the rocket, and to control the rocket during maneuvers one component of the guidance system of a simple rocket is the fins, which act as the steering of the rocket.


Thought I would post a few images I took on Tuesday morning , ( something a bit different ). Was lucky enough to go along on a helicopter ride around the Perth Airport to take photos of the airport and my works aircraft . Had to be at the airport for a 5 am take off on a Bell 206B Jetranger helicopter . The flight was with an aircraft photographer , flight sim landscape designer and the Pilot . We had to wait till about 545 before taking off as there was a fair bit of cloud cover holding back the light . the helicopter had all the doors removed for the flight so you were basically looking over the edge with just a seat belt holding you in . Photographing from a helicopter is a bit different from what Im used to with landscape photography , had no tripod for one , plus had to compensate for camera shakes plus there was a fair bit of vibration from the helicopter . The flight last for about 45mins and we ranged in height from 300ft to 1000ft around the airport and got around 150 images .
Will have some of my normal landscape images coming soon 🙂


A Texas group that searches for missing people is fighting a Federal Aviation Administration order to stop using drones for its searches, adding a new challenge to the agency’s authority to prohibit drones in the U.S.
The group, Texas EquuSearch, has been using small drones, or unmanned aircraft, since 2006 to map search areas and conduct searches itself. In February, the FAA in an email ordered the group to stop immediately.
Texas EquuSearch last month responded with a letter to the FAA asserting the agency has no legal authority to prohibit drone use and threatening to take legal action if the agency didn’t rescind its order in 30 days.

Origami Space Race
Produced by: Kapelica Gallery, Ljubljana
Origami Space Race is an initiative project for an alternative space program based on the use of origami space airplane and open source strategies. The project’s main aim is to produce a turn in the approach to the space technology, a turn toward more ecological technologies and into more open perception and greater accessibility of space. In this project, art functions as a stimulant for the idea being developed by Japanese scientists, who are planning to launch an origami aircraft from the International Space Station. This idea has the potential of becoming a starting point of a new generation of ecological spacecraft as well as other origami structures applicable in space. And this project would like to stimulate and contribute to these future inventions.


NASA called on EFM Global expertise to transport the James Webb Space Telescope (JWST), the most expensive piece of equipment ever shipped, from California, where it was assembled, to the launch site in Kourou, French Guiana.
To move the fragile JWST between the two locations, a distance of 5,800 miles, by land and sea, safely, efficiently, securely and discreetly, for handover 10 weeks ahead of launch.
Having planned the route, EFM Global chartered French cargo vessel MN Colibri to carry the James Webb Telescope in a bespoke shipping container, undertaking multiple port surveys/assessments and site visits. EFM arranged commercial container shipping – beating pandemic-inspired tailbacks through nous and connections – and air freight for supplies, transporting rocket fuel and eight ‘tube trailers’ from Miami to Kourou.
Also, among myriad extracurricular duties, EFM sourced/procured 17,000 hotel nights in Cayenne and Kourou for 300 Nasa workers.
The James Webb Space Telescope was launched to deadline, via an Ariane 6 rocket, on 25 December 2021. Designed to answer outstanding questions about the universe and to make breakthrough discoveries in all fields of astronomy, Webb produced astonishing results in its first 12 months with 19 years’ data and pictures to follow.


Russia Readies New Radar Station, Missiles Against U.S.-NATO Shield
Russian Information Agency Novosti
November 25, 2011
Russia's Baltic radar to monitor missile launches across Europe, Atlantic
MOSCOW: Russia's radar station in the Baltic exclave of Kaliningrad will monitor missile launches from the North Atlantic, as well as the future European missile defense system, the Aerospace Defense Forces chief said on Friday.
"We will be able to control the entire European continent and the Atlantic, including the European missile defense system," Lt. Gen. Oleg Ostapenko said.
The radar station is ready to go into operation as part of the national missile early warning attack system, he said.
In addition, Iskander tactical missiles will be deployed in the Kaliningrad region "in the near future," the general said.
Russia's air defense system will have the capability to intercept any type of missiles, any targets at any speed, including hypersonic ones, Defense Minister Anatoly Serdyukov said on Tuesday.
The new system, comprising air defense, missile defense, missile early warning attack and space control systems, should be up and running by December 1.
Ostapenko's remarks come after President Dmitry Medvedev said on Wednesday that Russia would move "advanced offensive weapon systems" to its European borders in response to a planned U.S.-backed NATO missile shield if talks on the project fail.
Moscow is seeking written, legally binding guarantees that the shield will not be directed against it. Washington, however, has refused to put its verbal assurances in writing.
Washington responded by saying it would not alter its plans for a European missile defense project, despite increasingly tough rhetoric from Moscow.

Kaliningrad missile early warning radar able to monitor Europe, North Atlantic - commander
MOSCOW: A radar station built in the Kaliningrad region will seriously enhance the information capabilities of Russia's missile early warning system, Russian Aerospace Defense Force Commander Lieut. Gen. Oleg Ostapenko told journalists on Friday.
"It will allow us to efficiently monitor missile launches over the entire European continent, as well as from the North Atlantic area, including the functioning and systems of the European missile defense shield," he said.
All efforts to build the radar in Kaliningrad and to put it into operation have already been completed, Ostapenko said.
"Specialists have already been trained and licensed to operate the station. We are prepared today to add this station to the general missile early warning system as soon as the supreme commander-in-chief issues such an order," he said.
The Kaliningrad-based radar has unprecedented qualities, he said.
"It will seriously expand the range of information gathering, enabling the country's supreme leadership to subsequently make decisions," the commander said.
The radar's technical and tactical features allow it to stand out among previous- generation radars. It is an ultra high frequency radar, which can measure parameters with a higher degree of accuracy.
"It consumes far less power, and the volume of its technological equipment is much smaller," Ostapenko said.
Such radars' new-generation advanced equipment has made it possible to seriously optimize their maintenance and cut personnel servicing them on a day-to-day basis, as compared with Dnepr-, Daryal- and Volga-type radars, he said.
"The results of this radar's preliminary trials showed that its main characteristics meet with required targets," the commander said.
High operational compatibility radars are built within a very short period of time, he said.
"This technology allows us to improve the station's technical capabilities of target detection, should such a need arise," Ostepenko said.
Russia's Voronezh-DM ultra high frequency, over-the-horizon long-range high operational compatibility radar has been deployed in the village of Pionerskoye in the Kaliningrad region. The radar is capable of detecting ballistic targets within a range of 4,000 kilometers to 6,000 kilometers.

C-27J Spartans Grounded.
The Royal Australian Air Force (RAAF) has decided to ground several of its C-27J Spartans after the discovery of structural cracking in these aircraft. This move follows the US Coast Guard’s decision to suspend the use of all 14 of its Spartans, citing the presence of cracks of varying degrees. The US Coast Guard stated that their Spartans would remain grounded until a thorough evaluation could be completed.
The manufacturer, Leonardo, had previously issued an Alert Service Bulletin instructing operators, including the RAAF and US Coast Guard, as well as the military forces of Italy, Mexico, and other nations, to inspect for cracks near the attachment points of the horizontal and vertical stabilizers to the fuselage.
A spokesperson for the Australian Defence said that the Royal Australian Air Force had initiated inspections on its C-27J fleet and identified similar structural issues. Aircraft found to have cracking will not be flown until a comprehensive engineering assessment has been conducted.
Leonardo issued a statement reassuring that the problem is fixable and should have minimal impact on operations. The manufacturer has already identified a repair solution, which can be implemented at customer premises by the operators without requiring significant effort. Leonardo emphasized that the reported issue is not expected to affect planned aircraft operations.
As of now, Australia operates 10 C-27J Spartans through No. 35 Squadron at RAAF Base Amberley. This squadron primarily focuses on peacetime operations such as search and rescue and aeromedical missions. The RAAF initially acquired the C-27J as a replacement for the Caribou, intending to fill the gap between the Chinook and the larger Hercules and C-17 Globemaster aircraft.


Navigating a new direction for space satellites
Ultra-precise navigation allows groups of small satellites to work together to outperform single larger units
7 April 2019
Man-made satellites getting smaller and more plentiful as scientists discover that groups of satellites working together can carry out many of the tasks currently performed by large, single devices more effectively and at lower cost.
A collection of small satellites working in unison is often called a distributed space system.
Basic forms are already in operation, such as constellations of satellites orbiting along similar trajectories, controlled centrally to provide constant communications coverage. There are also plans to develop them to perform complex tasks requiring groups of partially autonomous machines that can communicate with each other and fly in a precise formation to achieve a common goal. These could, for instance, deliver fuel or replacement parts to other satellites in orbit. More ambitiously, multiple small units could be launched into space separately and later autonomously assemble into a space station, or a craft designed for planetary exploration.
These smaller, distributed systems may be cheaper to launch, less prone to failure and easier to repair; but they require levels of navigational accuracy and positional responsiveness that are hard to achieve with current technology. “You need a higher degree of precision to enable these smaller satellites to interact, work closely together and possibly connect,” says Hesham Shageer, an assistant research professor at KACST. Shageer is also the principal investigator on a project working on navigation systems to control the next generation of miniaturized distributed space systems at the Centre of Excellence for Aeronautics and Astronautics (CEAA), a research collaboration between KACST and Stanford University in California.
The development of smaller electronic components and sensors have, in recent years, allowed satellite makers to pack greater functionality into increasingly smaller units. “Two key technologies are revolutionizing the way humans conduct spaceflight: the miniaturization of satellites and the distribution of payload tasks among multiple coordinated units,” says Shageer.
Keeping satellites on track
At the heart of the technology underpinning the group’s efforts is an instrument called the Modular Gravitational Reference Sensor (MGRS). Researchers at Stanford University first proposed the MGRS in 2004 as a way to achieve the precise position sensing and orbit stability a constellation of satellites would need to detect gravitational waves. These tiny ripples in space and time, caused by the movement of massive astronomical bodies, were first predicted by Einstein’s theory of general relativity, and detected for the first time in 2016 by ground-based detectors.
In essence, the MGRS is a box containing a metal sphere that, when on board a satellite in space, floats free at its centre, shielded from all non-gravitational forces, such as air resistance, solar wind, radiation pressure, and electro-magnetic forces. Within the box, optical sensors keep track of the precise position of the sphere. Its movement with respect to the box signals a shift in position of the satellite and allows for the precise measurement of gravitational forces. Thrusters can then be used to immediately counter the effects of gravity, and return the satellite to its orbit, and the sphere to its original central position.
Different forms of optical sensors can be used to keep track of the position of the sphere. The latest version of the MGRS developed by the Stanford University team uses a device called a Differential Optical Shadow Sensor (DOSS), in which pairs of laser beams are directed from the inner walls of the box at the outer edges of the sphere.
When the DOSS is in the centre of the box, the sphere’s edges block half of the light from each beam which would otherwise reach detectors positioned opposite their sources. Movement of the ball with respect to the box changes the intensity of the light reaching the detectors, allowing any change in position of the satellite to be measured. Four pairs of beams and detectors are positioned perpendicular to each other to track movement in three dimensions.
When a satellite moves through low-Earth orbit, it is affected by drag, which is the force generated by air resistance. The sphere at the centre of the DOSS is unaffected by drag, but the satellite itself is. The detection of this difference triggers the thrusters to amend the trajectory of the satellite in such a way that it can operate as if it was free from drag.
The latest prototype has also been redesigned to reduce noise and improve accuracy through the use of a fibre-coupled super luminescent light-emitting diode as the light source, a well-contained single structure and new amplifier electronics. The DOSS is able to check for small movements more frequently than other tools such as interferometers, which recombine beams of light after they have been split and made to travel along different optical paths. Satellites equipped with a DOSS can therefore make readjustments to their trajectories more quickly and achieve improved navigational precision.
“The position of the sphere within the laser beams provides a feedback loop to the satellite’s control thrusters which act in response to gravity to maintain the sphere in position,” says Shageer. “Existing technology allows the satellite navigation and control to be accurate to within a few metres, somewhere in the 3-5 metre range. With this newer technology, we could improve that to an accuracy of within a few centimetres.”
Working on resilience, accuracy and affordability
Plans to develop and test the sensor formed one of six collaborative research projects launched in 2014 with the creation of the CEAA. While Stanford University researchers had originally worked on the MGRS primarily for its potential as an astrophysics experimental tool, KACST scientists focused on demonstrating its capabilities and developing practical applications. Tests were carried out on a prototype form of the MGRS on board SaudiSat-4, a Saudi Arabian satellite launched in 2014. “It achieved all the performance requirements we had set for it,” says Shageer.
Shageer and his CEAA colleagues are working on new motion planning algorithms and software to allow the further development of distributed space systems with navigation capabilities that are accurate to within a few centimetres. They are using estimation theory, a branch of statistics designed to estimate variables when some parameters are missing, such as the location of a satellite that has stopped communicating. The group is also investigating the use of vision-based navigation, in which images collected by cameras on a satellite are used to amend its trajectory. They have been using Stanford University’s GNSS Navigation Testbed for Distributed Space Systems to test their novel algorithms.
The group aims to gather more data from the experiment on board SaudiSat 4 to further determine how it has performed over the past few years. Shageer also hopes CEAA’s work on motion planning algorithms and vision-based navigation will feed into NASA’s Restore-L mission, which aims to launch a robotic spacecraft in 2022 that can, for the first time, meet and refuel a satellite in low-Earth orbit. If the mission is a success, the spacecraft of tomorrow could be more affordable, sustainable, and resilient.

The runway can accommodate ALR 5 aircraft up to 50,000 lbs such as Dash 8, DC-3, Convair, Twin-Otter, King Air, etc. The 2400ft x 75 grass runway 06-24 is a convenient crosswind runway.


Ryze Tello Quadcopter Tiny Drones, the toy-drone was developed in partnership with DJI and Intel and promises to be the best drones for beginners on the market, without the controller. Ryze, a Chinese startup, unveiled something uniquely simple with the Tello. Designed for kids or people how just want to experience the drone-flying world without spending a few hundred dollars. It brings some fun features including mid-air flips, livestreaming and the ability to program. Furthermore, the Tello drone also packing some Intel’s smart tech to make it safe and easy to fly indoors.
The Ryze Tello is an incredibly small drone compared most of the airframes we’ve seen released so far, neatly fits into just our palm. Measuring just 98 x 92.5 x 41mm and weighs less than 0.55 lbs. so the FAA drone registration requirement doesn’t apply. The Tello drone is best suited to be flown inside thanks to compact airframe which make it easier to fly indoors. It’ll only be able to fly outside when there’s no wind at all. You can fly the drone straight from your smartphone or with an additional controller. However, using a controller makes everything much easier flying than directly from a smartphone so you may want to consider adding that accessory.
The Tello pack with the same flight stabilization technology and Intel Movidius Myriad 2 VPU same as the larger DJI Spark, which means you can launch it from your palm and control it with hand motions. However, Tello drone’s camera utilizes a 5-megapixel sensor that can only record 720p videos – the Spark has a 12-megapixel camera capable of capturing Full HD 1080p footage. The 5-megapixel camera isn’t fantastic, but it’ll do just fine on social media platforms where the quality is downgraded anyway. Tello is also useful when you want to chuck it in your backpack on a walk to get some worthy aerial shots. Flight time also cuts off at a maximum 13 minutes, compared to the Spark’s 16-minute battery life, although it’s astonishing that a drone this small can fly for so long. You won’t be going anywhere quick with this drone either – its max speed tops out at an 8m/s.
On the plus side, the Tello comes with special features you won’t find even on DJI’s drones. For one thing, the control interface includes a flip button for being fancy in the air or dodging any Nerf darts at a party. There are also several flight modes, including ones for shooting a quick 360-degree video and having the drone fly away and upward from you in one smooth motion. Ryze Tello owners will also be able to program their own flight patterns at home, using an included coding tool called Scratch, an MIT-developed coding system that allows kids to learn the basics of programming while having fun. Advanced users can also develop software applications for Tello using SDK.
Ryze Tello brings some serious performance to the world of tiny drones. It comes in at a dramatically low price that blows the competition out of the water. Great drone for kids or beginner who would like to experience the drone-flying world without breaking the bank.

LOG317-Procurement Strategy and Policy
Phoenix-Air is an African budget airline. Typical of all budget airlines, Phoenix-Air focus on cost management and high operational efficiency. For example,
Operating no-frills flight with destination in 2nd tier cities to reduce landing cost.
• Do only point-to-point flight, avoiding the need and potential complications of transferring passengers.
• Flying with a handful of aircraft types (less than three) to reduce variation, build economy-of-scale and streamlining its operational process and maintenance.
• Leverage on the internet and digitisation technology, i.e. e-commerce, automated checking in, baggage tagging, customer service chatbots to
• Land and flight staff are expected to multi-task, i.e. pilots could double up as a cleaning crew after all passengers alighted the flight as it prepares for the turnaround
Information on Phoenix-Air:
• Rank 8th on the ‘on-time arrival’ ranking by the regional African aviation authority, out of a total of 44 airlines, of which 30 are classified as budget airlines.
• Phoenix-Air pays a competitive remuneration package. The airline is considered by many as one of the top-5 employers in the airlines' industry in the African continent.
• The airline recently experiences an increase in work absentees resulting in flights delay, impacting the on-time arrival at their destinations. As a result, 50 flights (mostly latenight outbound) were cancelled. This is an increase from the preceding year.
• Recent customer survey indicates that customers are satisfied with the airline: airfares, service quality (ground handling and in-flight), aircraft cleanliness, Flight safety, flight scheduling and timeliness. The one area that did not score well is on the e-commerce booking platform. Customers commented that it is not intuitive and multiple steps are required to complete a booking, making it a tedious affair. This is exacerbated in places where the internet reception is poor. Calling the airline means a long wait, and when connected, the sales agents are not knowledgeable about the product nor have the authority to handle the request.
• The number of passengers carried by the airline has grown steadily. In 2018, the airline carried 800,000 passengers on 7,200 flights. One key reason for this growth is that the company enjoys either a duopolistic or monopoly on 30% of its routes.
With the liberalisation of airspace in the African continent, Phoenix Air will lose it oligopolistic hold on air routes. The company will have to prepare itself to face competition.
a) Analyse the four (4) perspectives of the balanced scorecard.
(b) Assess whether the balanced scorecard (BSC) approach should be used here. In the above scenario, is BSC a more appropriate performance measurement tool than the traditional financial approach i.e. relying on financial performance measures?
(c) Develop a balanced scorecard for Phoenix-Air. Propose one (1) goal along with a corresponding performance measure for each of the BSC perspectives.
