GLAST, an ambitious gamma-ray astronomy mission, has been the victim of a seemingly unending series of launch delays... but those may finally be over. GLAST is scheduled to launch no earlier than 11:45 a.m. Eastern time (15:45 UT) Wednesday, June 11. I have no idea if it will actually get off the ground or not, but I'll be watching just in case. I'll be live-Twittering the event, and it will be broadcast on NASA TV as well. If I can get my act together tomorrow I might even do a live video stream. We'll see.
