Todd May is not the typical NASA rocket boss. For starters, he never worked on the space shuttle program or any of the agency's previous, half-hearted attempts to replace it. A materials engineer by training. May spent nearly a decade of his 21 years with NASA working on the international space station before moving into space science. He helped lead the Marshall-based team credited with finally finishing and launching one of NASA's perennial problem children, the $700 million Gravity Probe B mission to test Einstein's theory of relativity.
