GRACE Earth science mission ends
Posted: Sun, Oct 29, 2017, 11:46 AM ET (1546 GMT)
NASA announced Friday that the Gravity Recovery and Climate Experiment (GRACE) Earth science mission had ended after problems with one of its two satellites. NASA said in a statement that battery problems on the GRACE-2 satellite kept it from producing enough power to operate its science instruments and transmitter for one final observing run. It and the GRACE-1 satellite will be deorbited by early next year. The GRACE mission, done jointly with the German space agency DLR, launched in 2002 for what was originally planned to be a five-year mission to measure variations in local gravity fields. Those variations allowed scientists to monitor movements of liquid water, ice, and the solid Earth. A next-generation mission, GRACE Follow-On, is scheduled for launch early next year.
