View Full Version : Gravity Map Released

SUMMARY: The Gravity Recovery and Climate Experiment (Grace) mission has created the most accurate map of the Earth's gravity field. The joint NASA-German Aerospace Center mission consists of two spacecraft connected by a cable which is able to measure fluctuations in the Earth's gravity to a precision of a few centimetres. They found that the gravity field can fluctuate by as much as 200 metres around the world. This gravity map will give future water level measurements better accuracy, and help scientists better understand the slow redistribution of mass on the planet.
