Does the Pope have the authority to baptize aliens (martians)? Does the Pope have the moral authority to baptize Martians? Or any power from the bible?

This is the article:


  Pope Francis says he would baptise aliens: 'Who are we to close doors?'

[In case of necessity], [a]nyone [, even a non-baptized person, with the required intention], can baptize [CIC, can. 861.2.], provided he use water and the correct [Trinitarian baptismal] form[ula]: "I baptize you in the name of the Father, and of the Son, and of the Holy Spirit. Amen." [cf. CCC V. WHO CAN BAPTIZE?, 1256]

In the case of extraterrestrials, there is doubt whether they are human, so a conditional baptism would be required: "If you are human, I baptize you in the name of the Father, and of the Son, and of the Holy Spirit. Amen."

From the Roman Ritual:


  A monster or abnormal fetus should in every case be baptized at least with the following expressed condition: If you are a human
  being, I baptize you, etc. When in doubt as to whether there is one or
  several persons in the deformed mass, one part is to be baptized
  absolutely, and the others each with the condition: If you are not
  baptized, I baptize you, etc.


[cf. CCC IV. WHO CAN RECEIVE BAPTISM?, 1246]
