Today's launch attempt was scrubbed (for the second time) due to weather – 3rd attempt will occur on July 4 – great day to have a launch!
Update: We are a go for launch, today July 4th!
If you like to follow the STS-121 launch and mission, visit the STS-121 Discovery page. It is pretty awesome to have access to all the real-time information, from crew conversations to video, all from the Internet – when I used to work at NASA (IBM for NASA on the on-board OS), access to such information was limited – now anyone can see, hear and learn, on real-time, at anytime.
Also, see TwitTV – Space Shuttle Discovery Web Cams for a list of cool Space Shuttle cams.
Many years ago I had the privilege of watching in person and close-by the launch of Discovery – one of the most exciting and awesome experiences ever, specially when having software controlling the vehicle…
Best of luck to the crew of STS-121 and Godspeed!
