The Shuttle Discovery landed today for the last time. I watched it live on Ustream.com starting about an hour out. It’s the beginning of the end of our shuttle program. In April Captain Mark E. Kelly will take Endeavour up for it’s last flight (STS 134). Then in June Captain Christopher J. Ferguson will take Atlantis up for the final shuttle mission (STS 135). It’s the end of an era. But more people watch Charlie Sheen “winning” on Ustream. This makes me sad. At least Sonic Booms and KSC (Kennedy Space Center) did trend on Twitter for a short time.
