It currently produces 1-5 liters of water vapor per second and gases include: carbon monoxide, carbon dioxide, ammonia, methane, methanol. http://blogs.esa.int/rosetta/2014/10/03/measuring-comet-67pc... We could put a self sustaining base on it or on similar comets in the future.

Also the surface temperature seems to be -68.15C (avg) - typical Syberia, only there is no atmosphere and sufficient gravity and magnetic field to protect from radiation.

Otherwise it's fine.

Sarcasm?

Nobody is going to walk on it naked. The conditions on the comet are amazing compared to the ISS, which is currently supporting life.

The comet has everything you need, water, organic material, shielding from radiation, decent size, raw material, energy.

That "magnetic field to protect from radiation" part is pretty important, though. (ISS is inside the Earth's magnetic field.)

All you need is a couple of meters of water or earth. The base would be inside the comet at complete safety anyway, and detection can warn you to get inside in case of increased sun activity.

It is really easy if you have just a little material:

The short film is very much worth a watch, if folks are wondering.

Good visuals, but the script is nonsense. They are really trying to invoke that warm feeling inside. Unfortunately watching Littlefinger posing as a deity, forced me to laugh. Using an unknown actor would sell it better. ( I'm not trying to be mean, that was just the impression I got. )

His character isn't a deity. I believe the background is that they're on an alien planet some time in the future and are just beginning to terraform it. They happen to be using "sufficiently advanced technology" (in the sense of Clarke's third law).

Exactly. I’m pretty sure that’s how it’s intended to be read.

For what it’s worth, I thought the dialog was excellently written. A scene like that more or less invites overwrought, ham-fisted lines but the writers exercised some remarkable restraint (and Gillen and the newcomer match it with their deliveries).

That makes more sense. The nano-bots indicate that at the start and I missed it. Still the dialogue is just so cliche, including a forced mini twist ending.

I'm very much looking forward to the lander doing its thing. The photos will be breathtaking!

Indeed, the mind bounds ahead with such endeavors approaching - what don't we just send a hundred micro-bots designed to harvest raw materials sufficiently well enough to construct on-sight new micro-bots, designed to harvest raw materials, and so on. Seems real easy, the more I think of it, to capture a comet and do something with it. Like, within the next 100 years or so, 'easy', that is - as in, well .. maybe getting easier and easier. Rockets and robots, babies, its all we'll need to get there and do stuff.

I think the way it spins would be a problem to bring humans on it.
