Acquiring Signals From A Speeding Satellite
2014-03-07 14:51:31

ESA Soaring high above Earth as they speed through space, satellites are difficult targets to track. Now a new approach developed in Europe is helping ground stations to acquire signals faster and more accurately than ever before. During launch, a satellite is flung into orbit with tremendous force, attaining speeds of over 28 000 km/h – about 40 times faster than a commercial airliner. A critical moment is when the satellite separates from its rocket and starts transmitting radio...

Antarctic Research Shows SMOS And GOCE Data Similarities
2014-01-09 12:58:44

Lee Rannals for redOrbit.com - Your Universe Online Researchers who braved the harsh conditions of the Antarctic ice sheet will help bring about a better understanding of what lies beneath the South Pole. Dome-C on the Antarctic Plateau is one of the coldest places on Earth. The region is extremely dry and is essentially a cold-barren white desert. While these conditions are not ideal for a vacation, they do offer a stable place to check the validity of data from the European Space...

Earth Gravity Altered By 2011 Japan Quake, According To GOCE Data
2013-12-03 13:50:29

[ 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...

No Damages Reported As GOCE Satellite Falls Back To Earth

[ Watch the Video: GOCE Safely Burns Up In The Atmosphere ] redOrbit Staff & Wire Reports - Your Universe Online A defunct satellite that had been mapping the Earth’s gravitational field fell back to Earth at approximately 7pm ET Sunday (01:00 CET Monday), the European Space Agency (ESA) has confirmed. The Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) probe re-entered the planet’s atmosphere during a descending orbital pass extending across Siberia, the...

ESA's Defunct GOCE Satellite Expected To Fall Back To Earth Soon
2013-11-07 10:14:38

redOrbit Staff & Wire Reports - Your Universe Online Beware of falling satellites this weekend, as a European Space Agency (ESA) probe that had been mapping the planet’s gravitational field is expected to plummet back to Earth within the next few days. The Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite was launched in 2009, and managed to remain in low-orbit some 160 miles above the Earth thanks to its ion engine, UPI reported on Wednesday. However,...

SWARM Mission Launch Postponed
2013-10-30 12:13:41

ESA The launch of ESA’s magnetic field mission from Plesetsk, Russia, has been postponed by about a week. The announcement from the mission’s launch service provider, Eurockot, follows the decision to replace a unit in the Breeze upper stage of the Rockot launcher. Originally scheduled for 14 November, the launch is expected to be delayed by about one week. More details will be given as they become available. The three-satellite Swarm mission aims to unravel one of the most...

GOCE Mission Data Used To Study Ocean Currnets
2013-10-28 12:57:20

[ Watch The Video: Ocean Currents In 1993 Through 2011 ] Lee Rannals for redOrbit.com - Your Universe Online Although the European Space Agency’s (ESA) Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite has completed its mission and is heading back to burn up in Earth’s atmosphere, it will be living on in spirit through another mission. The primary objective of the GOCE mission was to map Earth’s gravity with great precision. GOCE has been orbiting Earth...

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...

GOCE Mission Comes To An End
2013-10-22 13:11:50

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) announced on Monday its Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mission has come to an end. ESA said that after mapping the Earth's gravity for four years the satellite has finally run out of fuel, effectively ending the mission. GOCE's gradiometer instrument was the first of its kind in space and it helped to map variations in Earth's gravity with unrivaled precision. GOCE...

ESA’s Swarm Constellation Fueled For Launch
2013-10-16 11:31:27

[ Watch The Video: Swarm Launch: Simultaneous Separation ] ESA With launch just a month away, ESA’s Swarm constellation has been fueled. Engineers will soon be focusing on the careful task of attaching the three identical satellites to the upper stage of the rocket for simultaneous release into orbit around Earth. The Swarm satellites and all the equipment needed to prepare them for liftoff arrived at the Plesetsk launch complex in Russia just over three weeks ago. The cargo...
