NASA Goes for Star Trek Science: Bob Cassanova of the Institute for Advanced Concepts

Bob Cassanova heads the NASA Institute for Advanced Concepts, which has just awarded twelve grants for development of projects that are on the edge of technology, including antimatter propulsion and a food replicator. Emily Lakdawalla tells us where old satellites go to die...often, nowhere at all. And Bruce Betts delivers his weekly What's Up! report on the night sky, and a new trivia contest. Space news, too.
