Earth's gravity revealed in unprecedented detail (w/ video)

(PhysOrg.com) -- After just two years in orbit, ESA's GOCE satellite has gathered enough data to map Earth's gravity with unrivalled precision. Scientists now have access to the most accurate model of the 'geoid' ever produced ...

GOCE satellite achieves drag-free perfection (w/Videos)

(PhysOrg.com) -- ESA's gravity mission GOCE has achieved a first in the history of satellite technology. The sophisticated electric propulsion system has shown that it is able to keep the satellite completely free from drag ...

Out-of-fuel European satellite to come crashing down

A satellite monitoring Earth's gravity field since 2009 will run out of fuel "in the coming days" and eventually crash, with little risk to humans, the European Space Agency said Friday.

GOCE delivering data for best gravity map ever (w/ Video)

(PhysOrg.com) -- Following the launch and in-orbit testing of the most sophisticated gravity mission ever built, ESA’s GOCE satellite is now in ‘measurement mode’, mapping tiny variations in Earth’s gravity in unprecedented ...

GOCE's 'heart' starts beating

GOCE's highly sensitive gradiometer instrument has been switched on and is producing data. Forming the heart of GOCE, the gradiometer is specifically designed to measure Earth's gravity field with unprecedented accuracy.

Earth Explorer mission GOCE launches

This afternoon, the Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite developed by the European Space Agency (ESA) was lofted into a near-Sun-synchronous, low Earth orbit by a Rockot launcher lifting ...

Launch of European gravity probe delayed

The launch of a pioneering European satellite designed to map Earth's gravity field was delayed due to technical problems and will take place Tuesday, Russia's Khrunichev Space Centre said.

The satellite on the edge of space

GOCE (pronounced go-chay), the Gravity Field and Steady-State Ocean Circulation Explorer, was one of ESA's most remarkable missions. Operating in the lowest-ever orbit of any Earth observation satellite, GOCE was on the edge ...

Lifetime of gravity measurements heralds new beginning

Although ESA's GOCE satellite is no more, all of the measurements it gathered during its life skirting the fringes our atmosphere, including the very last as it drifted slowly back to Earth, have been drawn together to offer ...

Earthquake scars Earth's gravity

(Phys.org) —ESA's GOCE satellite has revealed that the devastating Japanese earthquake of 2011 left its mark in Earth's gravity – yet another example of this extraordinary mission surpassing its original scope.
