Discovery Launch

I am so relieved that everything went well with Discovery's launch. I hadn't realized I was holding so much tension over it. I just called my mom and anyone else I thought would care (and not read here). I am so glad that the problem sensor was well behaved for launch. In the end I don't think it will make a difference (that is what redundant systems are all about), but if anything bad had happened I think it would take NASA even longer to recover than for the Challenger. So no need to worry about that one aspect anyways; there is plenty of other things. For now things look well, but I will be thinking happy thoughts for them for the next 12 days.
