It says in the Shulchan Aruch:
ברכת הלבנה וזמנה ובו ד סעיפים: הרואה לבנה בחדושה מברך אשר במאמרו ברא
שחקים וברוח פיו כל צבאם חוק וזמן נתן להם שלא ישנו את תפקידם וכו': הגה
ואין לקדש החדש אלא בלילה בעת שהלבנה זורחת ונהנין מאורה (אגור):
rough translation:
"One who sees the moon in its renewed state makes the blessing,
"who has, with his word, created skies and with the breath of his
mouth all of their hosts, a decree and a time he gave in them that
they shouldn't change their cycles...". (note: and one should only
sanctify the moon at night at a time that the moon shines and its
radiance is visible"
It's a clear law that one has to see the moon in its renewed state, the moons of another planet are not "the moon", the moon and the sun are called in Bereishes "the two great luminaries" , they are totally different than other stars and moons in every way.. but besides for that, the mitzvah of Birchas Halvanah doesn't apply to other moons, jus ttake a look at Halachapedia note 1:
Why did Chazal choose to make this Bracha on the moon specifically?
Aruch HaShulchan 426:2 explains that since the moon is the closest to
Earth we are able to recognize Hashem’s control over nature easily.
Also, the moon is compared to Bnei Yisrael; just as the moon doesn’t
have any of its own light, so too Bnei Yisrael are only sustained
through Hashem and his Torah; just as the moon gets smaller and
bigger, so too Bnei Yisrael are always renewed.
As seen through Rambam hilchos Kiddush HaChodesh, the "molad" is calculated is based on the sighting of the new moon, which only exists on Earth, and which kiddush halvanah is based on.
There are many other proofs I can bring, but I think this get s the general idea across. Mitvos don't apply in space to things in space, meaning even if you;'re obligated in mitzvos like davening 3 times a day in space, but that's just following your own time you left from etc.... The moons of Jupiter and not at all the same as our moon. There's nothing anywhere in the Torah about making Kiddush "Halvanah" on something other than "the moon" itself. If anyone can find something suggesting otherwise, I'd be happy to see it :)
EDIT
also just to be totally clear, just look in the yehi ratzon of kiddush levana:
"Let it be your will.. to fill the deprecation in THE moon, so that
there shouldn't be in it any detraction, and the light of the moon
will be like the light of the sun, like the light of the seven days of
the Beginning, like it was BEFORE it's subtraction / lessening
(Meeut), like it says, "And Elokim made the TWO great luminaries", and
fulfill in us the verse that says, "and you should search Hashem, your
G-d, and David their King, Amen",
and King David is compared to THE moon in many places, I can quote those too, because the moon and king David is malchus of Atzilus, specifically OUR moon refers to malchus of Atzilus, not any other moon the universe.
