Planetary Caves' Role in Astronaut Bases and the Search for Life

Detailed Description

During the 2nd International Planetary Caves Conference, attendees explored a 1.6-kilometer-long lava tube cave, northwest of Flagstaff, Arizona. This cave, which is more than 700,000 years old, provided an ideal setting for discussions on formation processes, robotics requirements and astrobiological potential within Martian caves.
