[Harry Potter] Why don't wizards explore space?
gpt
Wizards don't have the scientific method. Pretty much everything they do is based on copying something that a smarter or luckier wizard came up with a thousand years ago. They're also deeply separated from muggles, so they are *way* behind on scientific knowledge.

Muggles figured out how to land on the moon based on centuries of observation and research. It required knowledge of astronomy, gravity, chemistry, and geology to know that we could put people on the moon, that they wouldn't sink into a quicksand pocket of moon dust, that they wouldn't be able to breathe on their own, etc.

Now, could wizards even go to the Moon? Maybe, although the only plausible method would be to apparate, but that spell is more difficult with greater distances. Chances are any wizard making the attempt would end up wildly off-target somewhere in space, spinning randomly before expiring swiftly.

Of course, they might prepare a bubble-head charm to bring have some air - but what about extreme temperatures or radiation? What about dealing with tumbling in space and not even being able to tell where the Earth or Moon is once a jump has missed?

But even more, how could wizards even know what to prepare? The only time in his life a wizard is likely to have been unable to breathe is if they've been underwater. They might not even be familiar with the concept of vacuum, let alone radiation or reduced gravity. Since they don't have the scientific method, the only way for them to discover this stuff is for wizards to voluntarily apparate into space (or command house elves to do it), die in horrible ways, and then study the cause of death. 

The biggest reason, though: Wizards don't know there's anything interesting up there. With their primitive telescopes they can barely make out features on the Moon, let alone Mars or Europa or Saturn. To wizards, the planets and stars are just tools for predicting the future. Wizards probably don't think of planets as being even the same kind of thing as the Earth - they're just floating colorful circles on a black canvas.
