NASA looking for Mars simulator participants
NASA is looking for participants for its next Mars simulation. The deadline for the second Crew Health and Performance Exploration Analog mission is April 2. Participants will spend a year inside the Mars Dune Alpha simulator at NASA's Johnson Space Center in Texas, experiencing typical environmental stressors and the limited resources of the Red Planet. Christiane Heinicke, a researcher for the Center of Applied Space Technology and Microgravity, joined CBS News to discuss the mission.
