(Newser) – After four years of mapping our planet's gravity, the European Space Agency's GOCE satellite has plunged back to Earth. The GOCE—Gravity field and steady-state Ocean Circulation Explorer—was last heard from 75 miles over Antarctica, Reuters reports. It is believed to have burned up on re-entry, with hundreds of pounds of surviving debris scattering somewhere in the Western Pacific. Its gradiometer, the instrument used to make gravity measurements, is made of materials tough enough to survive the fall to Earth, the BBC notes.

GOCE—the planet's lowest-flying scientific satellite—mapped Earth's gravitational field in never-before-seen detail, revealing how gravity's pull is uneven across the world. The satellite's fall to Earth, which was inevitable after it ran out of fuel a few weeks ago, was the ESA's first uncontrolled re-entry in decades. But since GOCE was relatively light at 1.2 tons, it didn't attract the same attention as other recent re-entries, including the crash of a failed Russian probe last year.

It had instruments on board that were designed to survive re-entry for future study but nobody knows exactly where it landed? Now that's real planning by very smart people. Not.

Uneven Gravitational pull, huh? That explains why my Stewardess friend has one saggingwhie the other one stands proud.. She also has one red eye and one green eye. Perplexing. Everytime we make out I don't know whether to stop or keep going....Badda Bing...Badda Boom! Who was it? Cicken Little tha cried, "The Sky is falling". ~Rick Magee, FL

"revealing how gravity's pull is uneven across the world" This is invaluable information for fat people. Imagine losing pounds simply by moving to a new location.
