On Nov. 10, 2013, https://www.space.com/23544-goce-satellite-falls-from-space.html”>Europe’s GOCE satellite fell to Earth. GOCE is short for Gravity field and steady-state Ocean Circulation Explorer. Its mission was to map Earth’s gravitational field. GOCE did this for four years. https://www.space.com/23310-europe-goce-satellite-fall-earth.html”>Then it ran out of fuel.
Controllers weren’t sure where GOCE would fall back to Earth or linger in orbit. Some people worried that it might crash into a populated area. However, the small spacecraft broke up in the atmosphere and didn’t cause any property damage.
It disintegrated about 50 miles above the Falkland Islands in the South Atlantic Ocean. The European Space Agency called the mission a success. GOCE lasted far longer than expected.
