Just looking at the temperature range on Mars. It's 1.5x the distance from the sun as earth and the surface temp ranges from a balmy 70F to -225F.
Elon specifically has this dream of colonizing mars, but it seems unrealistic. Perhaps in the future there could be an outpost where humans can visit for extended periods of time, but living there forever seems kind of sucky.
They're "wandering" stars, because they don't remain fixed in their positions like all the others. [About ungodly people] "They are wild waves of the sea, foaming up their shame; wandering stars, for whom blackest darkness has been reserved forever." Jude 13 Earlier in the book, in verse 6, it says "And the angels who did not keep their positions of authority but abandoned their proper dwelling", which I think is a parallel. The planets rebelled against their position, and judgement is waiting for them. It's also interesting to note that astrology makes idols out of planets, saying they have influence over people and our behavior.
"Flat earth is a psyop" is their latest campaign, trying to appeal to people's egos. Yet again. First you had to be a troglodyte to believe in flat earth, now you've fallen for the psyop. It's pretty clever, I have to give them that.
