At dawn this morning (Jan. 31) NASA launched an advanced Earth science satellite aimed at making measurements of our planets surface soil moisture and freeze\/thaw states from space that will revolutionize our understanding of the water, energy, and carbon cycles driving all life on Earth, aid weather forecasting and improve climate change models. <\/p>\n
NASAs new Soil Moisture Active Passive (SMAP) observatory thundered off the pad at 6:22 a.m. PST (9:22 a.m. EST) Saturday atop a two stage United Launch Alliance Delta II rocket from Space Launch Complex 2 on Vandenberg Air Force Base, California. <\/p>\n
The $916 million satellite successfully separated from the rockets second stage some 57 minutes after the flawless liftoff and was injected into an initial 411- by 425-mile (661- by 685-kilometer) orbit. The spacecraft then deployed its solar arrays and telemetry indicated it was in excellent health. <\/p>\n
Were in contact with SMAP and everything looks good right now, NASA Launch Manager Tim Dunn said. <\/p>\n
Deployment of the solar arrays is underway. We just couldnt be happier. <\/p>\n
SMAP separated from the second stage while pointed toward the sun as seen in the video below from a rocket mounted camera: <\/p>\n

SMAP is NASAs 1st Earth observing satellite designed to make high resolution global observations of Earths vital surface soil moisture content and freeze\/thaw cycle just below your feet. It will aid global forecasting and have broad applications for science and society. <\/p>\n
SMAPs combined radar and radiometer instruments will peer into the top 2 inches (5 centimeters) of soil, through clouds and moderate vegetation cover, day and night, to produce the highest-resolution, most accurate soil moisture maps ever obtained from space, says NASA. <\/p>\n
