Sounds like fun, fun, fun in the sun, sun, sun. But it doesn't sound like the kind of place to lie shipwrecked and comatose, drinking fresh mango juice, gold fish shoals nibbling at your toes.
Radiation is tough to protect against. LOE provides very significant protection, but as you move further out, that is lost. Being exposed to a solar storm could be life ending and the moon astronauts were lucky.
Every scale model of satellites and shuttles altitudes never really show the altitudes correctly. Geostationary orbits are 22,500 miles up, but the shuttle and space station are only 144 miles. Earth's diameter is 7900 miles. LEO, low Earth orbit, really is low.
I've seen no reasonable effective design to protect humans in space over the durations required beyond burying ourselves below ground and placing radiation warning satellites around the Sun so when it happens, we can run like chip monks and get underground FAST.
I saw a fireball in the sky over Vermont when I was in college, so it must have been 1997 or so. My god, the thing was huge. It looked larger than this to my eye, and it was less of a "streak" and more a ball trailing a tail of sparks. it was totally amazing.
I've never heard one, but people have reported atmosphere skimming bolides as making a sound like tearing canvas (but with loads of subsonics) and that there's no speed-of-sound time delay between visual event and sound event, which suggests that the sound produced at ground level is from some sort of induced electromagnetic effect as the bolide goes through the Earth's magnetic field's lines of force ...
@SJ_Edwards: No, no noise. But it was so large that it seemed close, however I didn't see any impact. Against the dark Vermont sky it was an intense sight.
Could the above photo be connected to the sudden appearance of Ugg boot advertisers infesting this post? Seems awful convenient that both showed up at around the same time... Invasion of the Bootyspammers anyone?

As my niece would say, "That just blows mine head off."

It isn't colonization until people are born and grow up there.

I am both relieved and a little disappointed.
