30 Minutes to Mars: part II

Mars is a fascinating planet, and NASAs journey to Mars has many challenges, and many possibilities. Dr. Jim Green, NASA planetary science division director and NASA Astronaut Stan Love continue to explore the next steps of sending humans to the fourth planet from the Sun in this bonus feature of 30 Minutes to Mars, 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 as NASA maps its journey to Mars.
