[Harry Potter] Are there any wizards outside Earth?

It seems like an easy task for them, they can magic away all the engineering challenges muggles must face to get out of Earth's atmosphere.

I'm thinking a wizard city on Mars would be a great thing as they wouldn't have to hide anymore and will live free from muggle influence.

It's not clear that it is an easy task. A firebolt can go from zero to 150 mph in ten seconds, which sounds like a lot, but it's only 0.68 g (as in gravity, not grams). And if it's accelerating horizontally, then combining that with the lifting force is 1.21 g. Either a top-of-the-line broom is only 21% better than a super cheap one that can barely fly, or they're using a different system for hovering. If it's the latter, then whatever system that is will probably stop working if they're too far from the ground, and using a firebolt's usual acceleration isn't even enough to hold it up.

They've talked about bubble-headed charms, but just covering your head isn't enough for space. Can it be extended to your whole body? And they've *never* talked about radiation. Maybe the last wizard to go to space got sick and died and nobody knows why.

Don't get me wrong. Getting to the moon with magic is *much* easier than getting to it without it. Even something as simple as using aguamenti to constantly add water to the engine would both keep the engine from overheating and significantly increase the efficiency, exponentially increasing the delta-v. Or adding a firebolt could give it acceleration for better than an ion engine with unlimited range, so long as it's already in orbit. But it's not clear that it's something a small group of wizards could randomly do, and it's not something that major magical governments decided to put a lot of effort into.

Also, some fanfiction theorizes that magic doesn't work in space.
