Food will be grown there in greenhouse-like structures, which will also help with oxygen, water can come from the surface, and if the people know what the f--- they're doing, and the settlement is strong enough to withstand the weak dust devils and dust storms of the planet, really nothing should go wrong technically. The energy they get will probably come from the sun. The only thing that could really go wrong has to do with the people themselves, they could go insane from only having the same people around all the time. ut that's why they're training, to prevent that from happening to the best they can.

Just a quick little thing on stars just for practice:

O (verly large, nearly giant, blue star, planetary syetm never gets beyond accretion)
B (very blue stars, not quite giant sized, lives for a few million years)
A (blue-white, lives for a few billion years)
F (white, lives for a few billion years--more than A-type)
G (yellowish white, lives for around 10 billion years)
K (orangeish, lives for more than 10 billion but less than 1 trillion years, not sure exact limits)
M (orange-red to deep red, live for over a trillion years, longer than our current universe's age, ha very large solar flares usually, making it hard to life to spring up on orbiting planets)
L-T-Y (colors differ with composition, these are the brown dwarf classes, which are not fueled by thermonuclear fusion)
D (Anywhere from yellowish to very blue, eventually will become more orange and even red before fading to black dwarves, are the remnants of dead sunlike and smaller, also ever so slightly larger stars)
Q (These are neutron stars, only about the size of a city with over the mass of the sun, usually around 3 times, also are the dead remains of stars around 3 times that of the sun)
X (Black holes: are infinitely dense and have masses usually over 4 solar masses)
H (other classes of stars put together, that are only theoretical, such as preon and quark stars)
BD (also one of my personal classes, the cooled off remnants of white dwarves, known as black dwarves, hence "BD")

Hey. Can you name some of the largest astronomical explosions?

Well, of course there was the big bang that brought the universe into existence (only happened once tho duuhh) Then there are Gamna Ray Bursts abd Hypernovae, then Supernovae, colliding back holes abd coliding neutron stars (colliding neutron stars can make supernovae or hypernovae ) anything smaller and the list grows exponentially

Hmm... is it a gamna ray, or a gamma ray?

And what order are they from largest to smallest? I know a supernova is just a smaller hypernova, but is a hypernova larger or smaller than a gamna ray or is a neutron star largest?

Aaahh, stupid keyboard, yes it is Gamma Ray

Gamma Ray Bursts are extreme versions of hypernovae, so besides the Big Bang itself they are the largest explosions in the entire universe.
