Colonize Deimos! First Step To Space Invasion.

February 11, 2018

Space colonization has to start somewhere, and it won’t be easy.

A well known problem is radiation. It is considerable in space. On the ground we are protected not just by the magnetosphere, but by the equivalent of ten meters of water (the atmosphere, exerting a pressure of one kilogram per square centimeter). Vicious, hyper reactive dust is one problem. Astronauts’ testimony on the Moon showed their suits couldn’t have worked for another outing (from the dust, getting in all the articulations of the suits). Mars’ dust is not any better.

Gravity, or lack thereof, is also a drastic problem. In space it can be fixed: just use rotation. Although it was not tried experimentally yet, it is technologically feasible (and a familiar feature of sci-fi movies). On planets, it’s another matter: it is not clear that Mars has enough gravity for human health: we, Earth critters, evolved in the last four billion years, with Earth gravity. Trying to compensate with exercise is NOT working in the International Space Station: exercise mitigates the problem, but some of the damage to deepest parts of the femur bone seems irreversible. The flight surgeon of NASA, James Logan, MD, has thought a lot about these problems.

GlouconX, a contributor to this site, gave this link, which I found very interesting:

Mr. Logan’s solution? Colonize Deimos! Deimos is one of the two captured asteroids which Mars uses as satellites, The idea would be to send boring robots, and establish a base there, ready for occupation. Ultimately, enough space for one million people and full ecology could be dug there. One would need water: it’s not clear whether there is enough there, or not, as Deimos’ composition is unknown.other asteroid, like the dwarf planet Ceres, have water, and even massive quantities of it, 27% of the total mass, and close to the surface, as ice!

Going there, to Deimos or Ceres, in force, depends upon nuclear energy, both to go, to dig, and to stay. And since actually the nuclear fission engine is straightforward, and was tested 50 years ago very successfully, the decision is more political than technological:

From Deimos, the telerobotic exploration, exploitation and colonization of Mars could conducted… This is Dr. Logan’s message, and I agree 100%. It was long clear to me that only nuclear energy provided the energy density (by a factor of thousands!)

Deimos’ location is superior to Phobos for telerobotics operations, and it’s plenty big enough. Perhaps we could put in orbit around it a gravity generating station?

Once again, for the doubters, as president Kennedy said, we do these things not because they are easy, but because they are hard. Actually we do them because they are harder than anything we would do otherwise. And why is hard lovely? Because we, as a species, have always tried to do harder things. We have evolved into challenge defying creatures whose minds can only properly work that way. And why thus? because that’s how we survive, as a species!

And for those who, disparaging us, claim to prefer ants, to our wonderful minds, I have an ant-eater coming their way…
