I am starting to think this could be possible.
Some research also probed that there are plans to build space elevators, and probably it will be possibl during this century: http://en.wikipedia....trial_elevators
The problem with elevators is that 36.000km is just too much for the cable right now, and the weight is incredible, however a space elevator in mars would be a lot easier (17.000 km and 38% gravity)

I can't tell if you are serious or trolling us (likewise for the yes votes in the poll).
To me the whole thing sounds like an obvious joke or hoax.

There may be a few other details to work out..the air isn't breathable, for one. Temperature moderation is another, NASA site says that
The temperature on Mars may reach a high of about 70 degrees Fahrenheit (20 degrees Celsius) at noon, at the equator in the summer, or a low of about -225 degrees Fahrenheit (-153 degrees Celsius) at the poles. Obviously this is very inhospitable for humans, but it is also of some concern for the electronics and mechanical parts of a Mars airplane and its instrumentation. In the mid-latitudes, the average temperature would be about -50 degrees Celsius with a nighttime minimum of -60 degrees Celsius and a summer midday maximum of about 0 degrees Celsius.
If you think that's appealing, you should come live in Saskatchewan
Further down the article it says that Mars is cooling but nobody knows why..we finally know what to blame our global warming on!

I am not enterilly sure but I though that outside international space station in the space the temperature is minimum (-273), so being on mars can't be any worse, they will need a lot of insulating material and a lot of energy (solar panels).
They are not bringing air to international space station either, they filter it (more energy).
What they discovered now, is that cosmic radiation is too high for them to travel (they would have a high % of developing cancer during the 7 month trip), they are trying to solve it increasing the speed of the journey, but that needs more fuel, wich is more money.

There is a 2nd factor in heating that you are not considering Fluffy.
Space is essentially a perfect insulator, the only way to lose heat is to radiate it via light, mostly in the infrared. This is a relatively slow way to lose heat compared to being in an atmosphere, even one as relatively warm(as compared to space) and thin(as compared to Earth) as the one on Mars.

*Didn't they have to fight with that on moon landing also?, Moon doesn't have an appreciable atmosphere, but a tiny one just to make the lower part of legs freeze?
