Query: Project Blue: Visible Light Imaging Search for Terrestrial-class
  Exoplanets in the Habitable Zones of Alpha Centauri A and B   Project Blue is designed to deliver a small coronagraphic space telescope
mission to low-Earth orbit capable of detecting an Earth-like planet in the
habitable zones of the Sun-like stars Alpha Centauri A and B within the next 4
years within a Mission of Opportunity budget envelope. The concept heavily
leverages emerging commercial capabilities -- including the telescope optics,
spacecraft bus and launch vehicle -- and emphasizes a public-private
partnership approach.
