It’s not that simple, unfortunately.

Mars lacks a magnetosphere, causing its atmosphere to be slowly stripped away by ionizing radiation from the solar wind. Even if you could provide the energy required to melt the ice caps on Mars, any resulting atmosphere would essentially be lost to space.

I dont want to alarm anyone but in the middle of this photo and slightly to the right there seems to be a galactic being thats almost fully formed. Looks like its about to put on its head. I hope it hasn't seen us.

Got nosey; according to this article by NASA, it's presumed the tail will "break off" over the course of its progenitor galaxy's lifetime; a long fucken time from now. Its thought to have been formed from a collision with a smaller, blue, "blob-like" galaxy - which is visible in the upper left of the Tadpoles' "head," inside one of its spiral arms - that has managed to get about 300,000 light-years away from its "victim" since.

All info gleaned from linked article.

I may have just misunderstood you point?

I thought you critized my idea of taking speed into account, by saying that objects in geosynchronous orbit would be stationary as seen from the ground. I just wanted to note that although that is true enough for this argument, such an object would still travel it's orbit at a significantly different velocity compared to the spot on the ground underneath.
