Broadcast live streaming video on Ustream

NASA is set to launch its Orion spacecraft on an unmanned test flight today, in an early step towards an eventual manned mission to Mars. The launch was originally slated for yesterday, but a combination of technical issues and weather conditions scrubbed the launch. The new window kicks off today at 7:05 AM ET, so tune in above and you don’t have to wait long to witness their first try.

And it’s off! We have liftoff and the initial launch looks good.
