The first flight of NASA astronauts from U.S. soil in nearly nine years finally has a launch date: May 27. The impact of small bodies hitting an asteroid pulverizes its surface, making new regolith, while seismic shaking produced by the impact causes older regolith to move downhill and fill already existing craters. Studies of a comet from beyond our Solar System have yielded insights into how other star systems may have formed, and the California Nebula is the final mosaic image taken by Spitzer.
