30 Minutes to Mars.

NASA has robots and rovers on the surface of Mars and is planning on sending humans there as soon as technically possible, but there are steppingstones to getting there, conducting valuable scientific research, and returning home safely. Dr. Jim Green, NASA planetary science division director and NASA Astronaut Stan Love explore the next steps and help answer the questions of what a crew might experience on the Martian surface; what kind of samples could be returned that would provide scientific value; and determine what would be most useful in sustaining a crew for short and, eventual, long-term stays on the Red Planet.
