Follow Up on the Seven Martian Caves

Now that NASA has discovered what they strongly believe are caves on the surface of Mars, they are trying to take full advantage of this opportunity. They are now trying to identify possible earth analogues, or places on earth that are similar to those caves on Mars, in both arid and cold environments. This article discusses robotics that might be able to explore caves on Mars, possible human establishments in the caves, communication problems in the caves, and the future of the Earth-Mars Cave Detection Program.
