DSCOVR Mission's NISTAR: NIST Advanced Radiometer

NISTAR is a cavity radiometer designed to measure the reflected and emitted energy in four broadband channels from the entire sunlit face of Earth to help improve understanding of the effects of changes in Earth's radiation budget. NISTAR will fly aboard the Deep Space Climate Observatory, or DSCOVR, spacecraft, scheduled for a 2015 launch.

DSCOVR is a partnership between NOAA, NASA and the U.S. Air Force. DSCOVR will maintain the nation's real-time solar wind monitoring capabilities, which are critical to the accuracy and lead time of NOAA's space weather alerts and forecasts. The satellite will also host NASA-funded secondary sensors for Earth and space science observations.

More photos of DSCOVR can be seen in NASA's Flickr gallery.
