best mars movie ive seen in a while. Just awesome that we've got robots driving around on another planet sending us pictures.

Would colour be too much to ask?

I still can't get over the sheer brilliance of that landing.

Very good..but they dropped the two viking landers in the 70s in exactly the same way

Erm no. The Viking landers used integral parachutes and rockets to slow their descent. Curiosity was delivered by a separate vehicle, which, once it had delivered its payload, fucked off somewhere else. That's very, very cool.

Yes ok..they used a skycrane..but it was just a twist on the same principle...I think the polar lander was the same?

They should have let Cameron put the latest 3D movie cameras on it...then maybe someone outside of geeksville would be interested in it.

It's about time we had a base on the Moon tbqfh.

Not much point really except as a training base for mars and we still havent figured a lot of the problems out with a human mars mission.

3D printing may solve some of the issues - they have already tested rocket parts made by a printer.

It could mean a massive difference in the payload - particularly if you can print using local materials.

I disagree with the first part but agree with the rest. Non-terrestrial manufacturing would solve a multitude of problems surrounding getting the stuff into Space. The savings made by not having to shift the stuff into orbit would eventually more then offset the cost of building the base in the first place. It would not only serve as a training base for Mars missions but for a whole host of other things as well.

Food production for example. The problem faced by astronauts experimenting with growing things in space is that in a zero-gravity environment the plant gets, well, confused as to which way to grow. Building massive greenhouses on the Moon would solve a lot of this because it does have gravity, hopefully enough to let them grow. Think about it, the Moon is a quarter the size of the Earth, even if you only use 20% of the place for food production you're going to solve world hunger at a stroke.

World hunger is not a problem of too little production, though.

Organic Moon potatoes, I like it.

Yeah right..the west throws away a third of its food..so lets grow some more on the Moon

The moon is not really terraformable - too small to sustain an atmosphere and tidally locked.

Thats why Mars is so attractive - in theory you could actually give it an atmosphere and have a cooler earth 2 - transferring whole biomes wholesale.

Need to work out what destroyed its original atmosphere though.

Also would need to work on its magnetic field to try and lower the radiation.

Still a second world would vastly increase the life expectancy of our species.

The lack of a powerful magnetic field means that the sun blasts much of the atmos into space?

Mars is too cool. Needs a big molten iron core :)

I favour the catastrophic impact scenario personally.

Mars almost certainly had liquid water on the surface 2 billion years ago and right by the asteroid belt you'd expect it to get regular recharging.
