Dr. Paul Spudis published two articles in recent days that caught my attention. The first discusses a proposed Chinese mission to the far side of the Moon, and the second discusses the search for life on Mars.
In total, the two are a continuing theme of questioning US space policy, and are a good read. Looking at both in a big-picture sense, one has to wonder why the US is choosing to pass up on developing cislunar space, treating it as nothing more than a proving ground for developing an eventual mission to Mars.
Food for thought.
