SpaceX had to scrub the Wednesday launch attempt of its Falcon 9 rocket due to upper-level winds, but will try again Thursday morning. The instantaneous launch window opens (and closes) again at 9:17am ET. This launch will occur from at Vandenberg Air Force Base, in Southern California.

There is heightened interest in this launch because, for the first time, SpaceX will attempt to “catch” one of the two payload fairings that enclose the satellite at the top of the rocket. The value of these fairings is about $6 million, and recovering and reusing them would both save SpaceX money and remove another roadblock on their production line for Falcon 9 rockets. These fairings will separate from the rocket at about three minutes after launch and are “steerable” in the sense that SpaceX hopes to guide them back to a target location the ocean.
