The Gamma-Ray Large Area Space Telescope, or GLAST, was launched into Earth orbit just a week ago (I've written about it a zillion times). What with all the stuff going on in space right now it might feel hard to keep up with GLAST, but then today's a happy day for you: GLAST has a blog! It's written by Steve Ritz, the GLAST Project Scientist, so he has some passing familiarity with what's what on the observatory. He's been keeping it fairly up-to-date, with a list of what GLAST is doing right now (going through testing before turning on the main instruments). I'll put it on my daily checklist to make sure I know what's going on. You should too. When GLAST starts doing science there'll be plenty to talk about.
