The two GRACE satellites, GRACE-1 and GRACE-2, were launched from Plesetsk Cosmodrome, Russia, on a Rockot (SS-19 + Briz upper stage) launch vehicle on 17 March 2002. The spacecraft were launched to an initial altitude of approximately 500 km at a near-polar inclination of 89°.
6 days ago · The mission consists of two identical spacecraft that fly about 220 km apart in a near-polar orbit with an average mission altitude of about 450 km. GRACE maps Earth's gravity field with accurate measurements of the distance between the two satellites, made possible with the K-band microwave ranging system.
The GRACE twin satellites, launched 17 March 2002, are making detailed measurements of Earth's gravity field changes & revolutionizing investigations about Earth's water reservoirs over land, ice & oceans, as well as earthquakes and crustal deformations.

Jun 6, 2023 · The Gravity Recovery and Climate Experiment (GRACE) twin satellites, which orbited Earth from 2002 to 2017, made detailed measurements of Earth's gravity field and improved investigations about Earth's water reservoirs, over land, ice and oceans.
Apr 26, 2018 · GRACE, twin satellites launched in March 2002, are making detailed measurements of Earth's gravity field which will lead to discoveries about gravity and Earth's natural systems. These discoveries could have far-reaching benefits to society and the world's population.
The NASA/German Space Agency (DLR) Gravity Recovery and Climate Experiment/GRACE Follow-on (GRACE and GRACE-FO) platform consists of two identical satellites that act in unison as the primary instrument. The two satellites comprising each mission orbit one behind the other in the same orbital plane at an approximate distance between the two ...
