Unfortunately the amount of delta-V you’d need to boost it to a parking orbit of some kind, or to the moon, would be deeply impractical. And it doesn’t have the shielding required to support any sort of deep space habitation.

I’d love to see some or all of it returned to be displayed in a museum, but it would probably be more expensive to do that than it was to build it in the first place. The vehicles to return it in whole or in pieces simply don’t exist right now, and on-orbit disassembly would be incredibly difficult and dangerous for astronauts to carry out.

Depends on where you are.

I’m in the Midwestern United States now, where summer is often pretty frustrating due to the high humidity. But I’m originally from Phoenix, where I really enjoyed summer (in the shade), because I love the feeling of warmth soaking into my bones, and I never got sweaty.
