The next Space Shuttle launch, this time for Endeavour, is scheduled for March 11 at (yikes) 2:28 a.m. Eastern time.
I won't be live-Twittering it. :)
However, NASA has a fleet of support stuff for you, the launch junkie, to learn all about STS 123, including a web site, a launch blog, and a live interview with STS 127 astronaut Julie Payette at 11:30 a.m Eastern time on March 10.
Night launches are very cool, but I'm not sure I want to stay up past 1:00 local time to watch it all. We'll see.
