[UPDATE: The rocket is sitting on the pad, and things are looking good as I write this (19:50 Mountain time), with one hour left before launch. Follow my tweets, or Kepler's!]
A reminder: Tonight at 10:48 p.m. Eastern (03:50 UT) is the scheduled launch time for NASA's Kepler spacecraft. I'll be live-tweeting it, and it will be televised on NASA TV. Kepler also has a twitter feed.
Also, the next Shuttle launch has been scheduled for March 11 at 21:20 Eastern time. If I can I'll tweet that one too (covering those is fun).
So hang out tonight and let's watch a very cool astronomy-based space shot!
