Where fifty years before, a congressman’s standard move to get reelected was to talk about the programs he had voted for, nowadays it was to talk about what he had blocked, stopped, frustrated, investigated, or marginalized.

We had this whole big beautiful place for discovery, and all we could think to do with it was wipe out everything that made it worth discovering.

Phobos is the innermost moon of Mars, only 16.7 miles (26.9 kilometers) in diameter but the larger of the two moons. Diminutive Deimos is a little over 7 miles (11 kilometers) in breadth. Scientifically, both Martian moons are oddballs. There is continual dispute as to where they came from. Just how did they get there? Conjecture about them being captured asteroids or cogenerated with Mars is debatable. These two objects are a cosmic detective story, and we need more clues to sort out their true nature. Years ago I stirred up a little more than Phobos dust by calling attention to a strange feature spotted on that moon. I termed this oddity a monolith, a very unusual structure. While there are those who view it as a large, rectangular boulder, visiting Phobos can categorize this curious creation, put there by the universe, or God if you prefer.
