Mars exploration is not mainly sought to search for another home for earthlings ,it is rather for scientific advancement. Rovers ,orbiters and other unmanned vehicles are being sent there since the sixties with some sample return and moderate mapping of certain areas, however a manned mission to Mars is yet a science fiction notion shown in so many Hollywood movies and it didn't become real yet. If the safety of the people sent there is guaranteed, then it would be an adventure for humankind worth experiencing . Already low cost manned mission proposals using current rocket technology are being made since the early 90ies. If in addition relatively low costs could be maintained ,then yes "Go Mars " :)

Why send humans to Mars? I mean a base on the Moon is viable and could be good for scientific research and to provide a base for future exploration etc, but what can humans do on Mars that ever increasingly sophisticated robots/rovers/probes cannot? Given the apparent risks in space travel, why put astronauts lives at risk for the sake of being able to say yes, we walked on Mars?

are we in the state of "abandoned earth!" now? at this time, not even one good scientist could prove that human beings can survive in Mars. don't be ridiculous.... after all, there could still be a better and enough place on earth to live in. :)

I am not idea.coz i dont care of that. There is far away me to Space flights.lol
