NASA Social on Earth Science Mission

A Jan. 28 NASA Social Media event at Vandenberg Air Force Base featured a briefing about the science and engineering of the Soil Moisture Active Passive (SMAP) mission and a behind-the-scenes tour of Vandenberg Air Force Base. SMAP is the first U.S. Earth-observing satellite designed to collect global observations of surface soil moisture.

UPDATE for Friday, Jan. 31: NASA is now aiming to launch the SMAP Earth-watching satellite on Saturday, Jan. 31, at 9:20 a.m. EST (1420 GMT) to allow minor repairs to the satellite’s Delta II rocket after some so-called “debonding” was detected in the booster’s insulation. You can watch live coverage of the launch on Saturday morning here, starting at 7 a.m. EST (1200 GMT) with commentary from NASA TV. Full Story: NASA Calls Off Satellite Launch Minutes Before Liftoff

Once in space, the satellite will make a global map of soil moisture levels ever three days or so. You can watch the launch live in the window below via NASA TV.
