A staple of the SciFi genre in games and literature is having to go colonize some far-off planet because a huge asteroid is about to Chicxulub us again. Sierra On-Line's disastrous flop Outpost* would be a prime example.
Something that never occurred to me at the time was this: There's
all this space infrastructure, right? The construction yard that built your
colony ship, the fueling station in orbit around Jupiter, your huge
colony ship itself... And you're going to head off into the great unknown to
colonize an inhospitable
rock and hopefully eventually terraform it?
Hey, I know an Earth-like
planet that would be super easy to terraform: That one that just got hit
by an asteroid. How about we turn around and land back home? Sure,
civilization's been wiped out by tidal waves, earthquakes, and
firestorms, but it's still more Earth-like than an airless rock in orbit
around Zeta Reticuli.
I was reminded that there was some hand-waving about further impacts being expected in order to obviate this possibility. If only we had a huge spaceship that could be used to nudge them off course... Oh, wait, we sent it to Zeta Reticuli.
bought a CD-ROM drive, switched to Windows 3.11 from DOS, and added
another two sticks of RAM just to run that dog. Imagine my chagrin.
