As Tucker points out, the experiments on the long-term effects of life in zero gravity demonstrate that humans do not belong in space. “The news has not been good. Muscles atrophy quickly and—for reasons yet unknown—the human body does not manufacture bone tissue in space.”

I totally agree with this article.

Man requires gravity to survive and not just any old gravity, it has to be exactly the same force as on the Earth.

A manned space voyage to Mars is a planned suicide mission for the crew not to mention a huge money sink.

I love Star Trek but its a modern fairy tale. Face it, man was made for Earth and there is no other planet close by like it.

Agreed. Until we can manufacture artifical gravity, long term space travel is best suited for the robots. Besides, robots are cheap to build and can work non-stop. Thats not to say that humans shouldn't explore the other planets, its just admitting that we don't have all the answers yet.
