VANDENBERG AIR FORCE BASE, Calif. – Workers secure the Delta II interstage adapter, or ISA, for NASA's Soil Moisture Active Passive mission, or SMAP, to the rocket's first stage in the mobile service tower at Space Launch Complex 2 on Vandenberg Air Force Base in California. Processing of the United Launch Alliance Delta II rocket that will loft SMAP into orbit is underway at the pad. The ISA connects the Delta II first and second stages and encloses the second stage engine and thrust section. The spacecraft will provide global measurements of soil moisture and its freeze/thaw state. These measurements will be used to enhance understanding of processes that link the water, energy and carbon cycles, and to extend the capabilities of weather and climate prediction models. The data returned also will be used to quantify net carbon flux in boreal landscapes and to develop improved flood prediction and drought monitoring capabilities. Launch is scheduled for November 2014. To learn more about SMAP, visit http://smap.jpl.nasa.gov. Photo credit: NASA/Randy Beaudoin KSC-2014-3505
