It's improvisational Jazz. The jam session will end when they're
dead. They'll be fine; plenty of water; at least when they found
the running water tap. Before that they had to use solar heaters
to melt the ice, which was hard because the sun was so far away.
They're not telling NASA about the oxygen pockets hidden under
the soil though. That'd spoil their gig because then EVERYBODY
would be going up there.
