Gravity Recovery and Weather Testing in the Study of Solid Earth (GRACE) mission
Gravity Recovery and Weather Testing in the Study of Solid Earth (GRACE) mission NASA and the German Aerospace Center collaborated on the GRACE project (Gravity Recovery and Climate Experiment). From its launch in March 2002 through the conclusion of its science challenge in October 2017, twin spacecraft amassed particular measurements of the Earth's gravitational subject anomalies. Launched in May 2018, the GRACE Follow-On (GRACE-FO) is a continuation of the assignment of the usage of very similar tools. Two equal satellites are part of the GRACE programmed , which is tracking in a north-south orientation. The K-band Ranging (KBR) system of the GRACE project can come across minute versions inside the inter satellite distance with a micrometer degree of accuracy. The top notch accuracy of the gravity facts generated by GRACE is essentially because of the interplay of the special satellite configuration and the ideal measurements machine.
