> humans will settle Mars soon. > -Not happening. Primarily due to radiation and general life support problems. You must be kidding. We have fastest progress in launch systems since 1960s. Seriously, when was the last time multiple spaceships for human spaceflight carried tests at the same time in USA alone? Radiation and weightlessness - two biggest roadblocks for interplanetary flights - are known for quite some time, there are some plans and propositions, even though experiments are mostly long-term ISS flights. But it's hard not to see progress - would you say, for example, that Moon flight can't be used as a stepping stone in preparing Mars expeditions?
