Interesting, though it's more of an exercise in pride for many. But it could be useful, since we would need to learn how to make efficient, recyclable, in the first place to do so, which would benefit us here.
Also, Mars would be a pain in the ass, since it's a low G, frozen, irradiated desert.
Venus is closer, as big as us, and has cloud cover.
Simple as proping a baloon with earth atmosphere.
But i guess if you don't stick a flag in the ground like a conquistador, it doesn't count.
