Все сбывается, как и было обещано.

A European satellite is facing a fiery doom next month, when it is expected to begin falling from space to end a successful mission to map Earth’s gravity. The spacecraft runs out of fuel in October, but exactly when and where it will fall to Earth isn’t yet known.

The fiery re-entry of the Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite, which the European Space Agency has billed as the “the Ferrari of space,” will occur about two or three weeks after the satellite runs out of fuel in mid-October, ESA officials said.

“The affected area will be narrowed down closer to the time of re-entry,” ESA officials explained in a statement. “Taking into account that two-thirds of Earth are covered by oceans and vast areas are thinly populated, the danger to life or property is very low.” [6 Biggest Spacecraft to Fall Uncontrolled From Space]

About 40 metric tons of human-made space debris rains on to Earth every year, but the risk of any of it hitting somebody is lower than being smacked by a meteorite, ESA added.

The $450 million gravity-mapping GOCE satellite launched in March 2009, with ESA dubbing it “the Ferrari of space” due to the satellite’s aerodynamic design, which was required to counteract the drag of atmospheric particles whizzing by in its low orbit around Earth. The satellite skims above Earth at an altitude of just 139 miles. By comparison, the International Space Station orbits at about 249 miles.
