arnold asked the Naked Scientists:
1) The atmosphere is much thinner on mars so heat loss by convection would be very greatly reduced. So the cold is not as big a problem as suggested.
2) To seriously colonise Mars, humans would need to spend at least a third of each day active in a 1 G environment. (Sleeping and the rest of the time in one third G)
This could be achieved by building a 1 G spacecraft (a spinning wheel design and landing it on mars using huge parachutes and retrorockets. The ship would be very large indeed and would need to be constructed in space much like the international space station which is quite large. The 1G ship would be at least five times the size of the ISS maybe ten times but this is feasible given world cooperation.
3. Direct solar heating could achieved by via a clear dome on the landed craft and martian rocks used to store the heat like a storage heater. Using solar electric panels would be wasteful for heating purposes, direct solar heating is best.
4. The martian winter is one of our years long so best to set up camp not far from the equator to minimise the problem. There is probably frozen water there too.
5. Mars could be terraformed by seeding genetically modified lichens and bacteria. This could create an oxygen rich atmosphere in a fairly short time of maybe 100 years. The planet would also warm up and seas would form.
If you have any contacts in NASA then I would be grateful if you could put them in touch. I would like to explore my idea for a constant 1G spaceship which could make interplanetary trips and eventually be landed on Mars. The difference between other concepts and mine is the craft would have a constant 1 G through an acceleration range of _ 1G. (Very comfortable)
Regards
Gareth
