The Mars Colony

Self Sustaining? Not in the near future, best defense against a PKA would be a well developed space infrastructure- the ability to get stuff in to LEO quickly.

Economic Incentive would be farming (in domes and underground) to support mining in the Asteroid Belt. (see below)

Minimum population requirements are moot, genetic material could be transported and stored to breed future colonists. Eventually sending probes with such genetic material and the gear to artificially gestate new humans to other stars would be a good idea.

There would have to be a remarkable advance in spacecraft propulsion to make it profitable to mine gold on Mars, let alone the worthless rock that it is primarily composed of. I think the day will come when it is economically feasible to exploit extraterrestrial resources, but we're a long way from it at present.

Doubt we would go to Mars for mining, Asteroids are better sources of rare ores, talking up to tens of trillions of $ per asteroid here. Hollowed out Asteroids also make good colonies or even spaceships.

Also asteroids are not just found in the space between Mars and Jupiter but near our orbit. Sometimes they are even closer to Earth than the Moon.

Then we are agreed. How marvelous!

True, but most official sources indicate that the Earth will have run out of Aerosmith by the time we can develop the technology to drill on asteroids, making the mission all but pointless.

Aerosmith?

I know its a band but Huh?

BTW They just flew a space probe in to an asteroid a few years ago to see what its made of on the inside. In other words they blasted a lot of potentially valuable ore in to the cosmos

Kinda like a Gulf Oil Spill in space. All we need is a ship in space to collect and process the ore then crap out the good bits in the direction of Earth.

I was sure everyone would get the reference. Aerosmith did the theme song for "Armageddon", and while the song was a hit, the movie sucked, hence "making the mission all but pointless".

You know I had forced that horrid movie out of my brain along with Star Trek V! Thanks for making me remember!

Its late, I would have gotten the joke eventually.
