Planetary Caves

As USGS scientist and planetary cave enthusiast, Glen Cushing, points out, "Caves are important to the future of planetary exploration because they are believed to provide shelter from a range of harsh surface conditions, maintaining near-pristine surfaces and relatively stable microclimates." See links on this page to explore further.
