Today, September 8th, watch a live launch of NASA's mission to land on an asteroid, retrieve samples, and bring samples back to Earth, the OSIRIS-reX probe. In my experience, watching any launch is exciting. No, my company is not involved, but this is a very interesting mission.
Live coverage starts at 4:30 EDT, launch is currently scheduled for 7:05pm. There are two sites you can use : NASA TV at www.nasa.gov/nasatv, or from the ULA at www.ulalauch.com.
