What is GOCE?
ESA's dart-like Gravity field and Ocean Circulation Explorer (GOCE) Earth Explorer orbited as close to Earth as possible - just 260 km up - to maximise its sensitivity to variations in Earth's gravity field. Launched in 2009, GOCE's state-of-the-art gradiometer mapped Earth's geoid to an unprecedented level of accuracy, opening a window into Earth's interior structure as well as the currents circulating within the depths of its oceans.
The GOCE mission came to a natural end in October 2013 when it ran out of fuel and reentered our atmosphere on 11 November.

Latest Mission Results News

Despite having completed its mission in orbit over six years ago, ESA's GOCE gravity mapper continues to yield new insights into our planet. Thanks to this extraordinary satellite, scientists now have a much clearer view of the secrets that lie deep below one of the most remote parts of the world: Antarctica.

A thorough understanding of the ‘solid Earth' system is essential for deciphering the links between processes occurring deep inside Earth and those occurring nearer the surface that lead to seismic activity such as earthquakes and volcanic eruptions, the rise of mountains and the location of underground natural resources. Thanks to gravity and magnetic data from satellites along with seismology, scientists are on the way to modelling inner Earth in 3D.

Ten years ago, ESA launched one of its most innovative satellites. GOCE spent four years measuring a fundamental force of nature: gravity. This extraordinary mission not only yielded new insights into our gravity field, but led to some amazing discoveries about our planet, from deep below the surface to high up in the atmosphere and beyond. And, this remarkable mission continues to realise new science today.
It was five years ago this month that ESA's GOCE gravity-mapping satellite finally gave way to gravity, but its results are still yielding buried treasure – giving a new view of the remnants of lost continents hidden deep under the ice sheet of Antarctica.
