[ Watch the Video: Earth's Gravity Was Affected By 2011 Japanese Quake ] Lee Rannals for redOrbit.com - Your Universe Online Japan’s devastating earthquake in 2011 left its mark on more than the town of Fukushima. The European Space Agency (ESA) says that it had an impact on Earth’s gravity as well. Scientists used data from ESA’s GOCE satellite to show the effects of the 9.0 earthquake that struck east of Japan’s Honshu Island on March 11, 2011. The strength of gravity...

GOCE Mission Ends Work Just Begun
2013-10-23 12:40:46

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency’s (ESA) GOCE mission ended earlier this week, but the mission’s discoveries have only just begun. The ESA said that although the GOCE gravity satellite is entering its final weeks in orbit, the most exciting scientific analysis of the mission’s data is just beginning. GOCE has the first three-dimensional gravity gradiometer in space and it orbits lower than any other research satellite. The satellite has...

A European gravity observation satellite has been hit by a second computer glitch and is not able to transmit its valuable data down to Earth.Europe's Goce satellite, launched on 17 March, 2009, is a satellite carrying a highly sensitive gravity gradiometer which detects fine density differences in the crust and oceans of the Earth. Its main mission is to make the most precise maps yet of how gravity varies across the globe.The satellite suffered a processor fault in February forcing...

GOCE's sophisticated electric ion propulsion system has been switched on and confirmed to be operating normally, marking another crucial milestone in the satellite's post-launch commissioning phase. The success of GOCE's ultra-sensitive gravity measurements depends on finely controlling the satellite's orbit and speed. The push from the thruster must be just enough to compensate for the tiny amount of drag generated by the few wisps of atmosphere at GOCE's orbital height. No normal jet engine...
