Why are we considering manned flight to
Mars ?
CAPE CANAVERAL, Florida (AP) -- How do you get rid of the body of a dead astronaut on a three-year mission to Mars and back?
When should the plug be pulled on a critically ill astronaut who is using up precious oxygen and endangering the rest of the crew? Should NASA employ DNA testing to weed out astronauts who might get a disease on a long flight?
With NASA planning to land on Mars 30 years from now, and with the recent discovery of the most 'Earth-like' planet ever seen outside the solar system, the space agency has begun to ponder some of the thorny practical and ethical questions posed by deep space exploration.
Unmanned flight is so much more economical and easier. Why send a man to do a machine's job?
