The Earth Fire Alliance's suite of satellites will fly at a lower orbit — about 370 miles from Earth compared with NOAA's 22,000 miles — affording even more granular information in real time ...
The Gravity Recovery and Climate Experiment ( GRACE) was a joint mission of NASA and the German Aerospace Center (DLR). Twin satellites took detailed measurements of Earth's gravity field anomalies from its launch in March 2002 to the end of its science mission in October 2017. The two satellites were sometimes called Tom and Jerry, a nod to ...
