Europe's Goce gravity satellite probes Earth's mantle

Europe's Goce gravity satellite has provided striking new visualisations of the Earth's deep interior.
Its gravity data has enabled variations in the density of rock to be traced up to more than 2,000km below the surface.
The maps, published by the journal Nature Geoscience, is helping to reveal how material moves up and down, driving a range of geological phenomena.

European Space Agency's Goce satellite falls to Earth

The European Space Agency's (Esa) Goce satellite has re-entered the Earth's atmosphere, burning up in the process.
Early estimates suggested any surviving debris could have fallen somewhere along a path through East Asia and the Western Pacific to Antarctica.

GOCE gives in to gravity

Close to 01:00 CET on Monday 11 November, ESA's GOCE satellite reentered Earths atmosphere on a descending orbit pass that extended across Siberia, the western Pacific Ocean, the eastern Indian Ocean and Antarctica. As expected, the satellite disintegrated in the high atmosphere and no damage to property has been reported.

The European Space Agency (Esa) is preparing for the fiery fall to Earth of its Goce gravity-mapping satellite.
The sleek spacecraft is flying just 224km above the planet, but its special electric engine that maintains this altitude is about to run out of fuel.
Current estimates suggest this could occur anytime between the end of this month and the start of November.

GOCE the first seismometer in orbit

Satellites map changes in Earth's surface caused by earthquakes but never before have sound waves from a quake been sensed directly in space - until now. ESA's hyper-sensitive GOCE gravity satellite has added yet another first to its list of successes.
Earthquakes not only create seismic waves that travel through Earth's interior, but large quakes also cause the surface of the planet to vibrate like a drum. This produces sound waves that travel upwards through the atmosphere.

GOCE settles debate on sloping sea

For decades, scientists have disagreed about whether the sea is higher or lower heading north along the east coast of North America. Thanks to precision gravity data from ESA's GOCE satellite, this controversial issue has now been settled. The answer? It's lower.

Goce gravity mapper surfs atmosphere

Europe's ultra-low-flying gravity-mapping satellite, Goce, is being manoeuvred even closer to the planet. The arrow-shaped spacecraft has spent most of its mission at an altitude of 255km - that's about 500km below most other Earth-observing missions.

GOCE's second mission improving gravity map

ESA's GOCE gravity satellite has already delivered the most accurate gravity map of Earth, but its orbit is now being lowered in order to obtain even better results.
The Gravity field and steady-state Ocean Circulation Explorer (GOCE) has been orbiting Earth since March 2009, reaching its ambitious objective to map our planet's gravity with unrivalled precision.
