NASA has been busy

Chris Howard wrote to tell us about a new chamber to trap antimatter. Eventually antimatter may prove a cheap energy source for interplanetary exploration (as in Star Trek). moonboy contributed this link to a new plasma engine NASA is developing. Finally in related news, Tom Rothamel informed us of a setback for the Delta III rocket (i.e. a successful test, since those are the ones that find bugs): "Well, the new Delta III rocket's first test flight just exploded. I saw it on RealVideo from Boeing."
