Scientists with NASA's Kepler mission today announced the confirmation of the discovery of two Earth-sized planets around another star. However, the two exoplanets are too close to their sun to be hospitable to life (as we know it anyway).
Meanwhile, the new head of NASA's Science Mission Directorate has plenty of "hands-on" experience in repairing and upgrading scientific spacecraft in orbit. Former astronaut John Grunsfeld helped to service the Hubble Space Telescope on three different Shuttle missions.
