Unfortunately it has once again been postponed this time I think Monday, 1:30(or 1:00) eastern time, for those of you who live in the U.S. Otherwise find it live on
www.NASA.com. Google "live NASA channel". That's how I found it and the announced it was to stormy and in case of an accident it would be impossible to return. I actually don't think it will be on live television, but definitely on NASA channel online.
For those of you who didn't know it's sending equipment to a Japanese space lab and is manned. So please hope it is a success!
