Musk wants to colonize Mars. NASA wants to colonize the moon. Please stop. I think these are not good ideas. Send robots. Send cameras. Send remote controlled laboratories. Human beings can only live on this earth. We need the earth’s 1G gravity. Otherwise human bones, hearts, and organs deteriorate and we die.
I understand the purpose of NASA is space exploration. I understand that human space exploration is more dramatic than robot exploration. I understand that dramatic dreams raise more money. But please do not try to colonize extraterrestrial bodies. They cannot support human life.
There is so much to learn about outer space, and human beings do not belong there, but human exploration can proceed much better without trying to force the human body into unlivable conditions.
