Elon Musk-led SpaceX has successfully launched twin NASA satellites GRACE-FO (Follow-On) that will track Earth’s water Cycle i.e. water movement and ice melt.
It was launched onboard of SpaceX’s preflown Falcon 9 Rocket from Vandenberg Air Force Base in California, US
GRACE-FO is a joint project between National Aeronautics and Space Administration (NASA) and German Research Center for Geosciences (GFZ).
It is follow-on mission to original GRACE mission, which had mapped Earth’s water and ice by measuring changes in Earth’s gravity field from 2002 to 2017.
