Apr 23, 2013 · Since 2002, NASA's twin GRACE satellites have mapped Earth's gravity (the attractive force exerted by its mass), enabling scientists to see these differences and monitor how they change over time. Watch the visualization for a tour of Earth's gravity field.
Jun 15, 2016 · In a new study published in Scientific Reports, gravity field data collected over the entire planet between 2009 and 2013 by the European Space Agency’s Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite has been mapped, revealing many of Earth’s internal features, such as magmatic plumes welling up toward the surface.
Gravity anomaly map from GRACE. Currently, the static and time-variable Earth's gravity field parameters are being determined using modern satellite missions, such as GOCE, CHAMP, Swarm, GRACE and GRACE-FO. The lowest-degree parameters, including the Earth's oblateness and geocenter motion are best determined from satellite laser ranging.
