Following an amazing display of technological prowess that used an intricate sequence of critical steps to bring NASA's Curiosity rover from orbit to standing on its six wheels on the surface of Mars, the most ambitious search to date for life on the Red Planet will begin.
Curiosoty, a one-ton, nuclear-powered rover chock full of scientific instruments, is scheduled to roam Mars for two years searching for evidence that life once existed-- or perhaps still exists-- on the little world next door.
Many Americans woke up this morning to news not only of Curiosity's successful landing, but also of another mass killing, this time a shooting at a Sikh temple in Wisconsin. The two events tell of the heights educated, discipliined humans can reach, as well as the depths to which humans can fall.
