Kinda like your mo.... uhh... kinda like Ridge A in the Antartic, then.

Screw the Moon. I still want to hollow out Deimos and slap an ion thruster on it so I can use it as a generation ship and colonize Tau Ceti. And that is just not going to happen without a permanent Mars colony.

They exert about the force a peice of printer paper does on your hand in Earth's gravity. They are useful for small space probes that need to travel vast distances, the force eventually adds up enough to make a small craft go very fast, but you would need some alternative thrust source to escape the Martian orbit. Also, you'd probably have cover a large portion of Deimos with an array of ion thrusters for that long of a trip, 12 lightyears. You might get there in 50-100 years.
We're actually aiming for something like three centuries, which would require an average speed of merely 0.04c. We might have to look into slightly more powerful propulsion, but we do have a long time to accelerate. Slow and steady wins the race.

Nah, you just jump out of the ship when you pass your destination.

Also. Who says you have to decelerate the entire craft?
To our knowledge, no planets have been detected in orbit around any star except Sol, as they are simply not very bright objects. We're counting on there being some, though.
What? Plenty of planets have been detected, just not from direct light observation. Even then, there's some technowizardy involving the presence of planets affecting the spectrum of the light observed in a star.

I don't know why it's surprising or interesting that there is some H2O on the moon and other planets. I didn't think it was *that* rare a molecule. Aren't there even ice meteoroids flying around out there? or did I just get that idea from some video game I played?

Ba dam bum
Kinda like your mo.... uhh... kinda like Ridge A in the Antartic, then.
You obviously aren't scaling up the right slope.
But seriously, folks. We need a moon base asap!

As long as they're not building a bypass.
