No Damages Reported As GOCE Satellite Falls Back To Earth
2013-11-11 07:39:22

[ 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...

GOCE Mission Data Used To Study Ocean Currnets

[ 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...

Gravity Satellite Mission To End This Fall
2013-09-14 03:50:00

April Flowers for redOrbit.com - Your Universe Online After four years of working to map out Earth's gravity, the European Space Agency's (ESA) Gravity field and steady-state Ocean Circulation Explorer (GOCE) mission is nearing its end. The satellite, which has been orbiting Earth since 2009 at the lowest altitude of any research satellite, will reenter our atmosphere soon. GOCE has been called the "Ferrari of space" because of its sleek, aerodynamic design. This designer spacecraft has...

Debate On Sloping Sea Settled By GOCE
2013-02-15 15:17:53

ESA For decades, scientists have disagreed about whether the sea is higher or lower heading north along the east coast of North America. Thanks to precision gravity data from ESA´s GOCE satellite, this controversial issue has now been settled. The answer? It´s lower. Many might assume that the height of the sea is the same everywhere — but this is not true because winds, currents, tides and different temperatures cause seawater to pile up in some regions and dip in...

GOCE’s Second Mission To Improve Gravity Map
2012-11-16 12:22:31

ESA ESA´s GOCE gravity satellite has already delivered the most accurate gravity map of Earth, but its orbit is now being lowered in order to obtain even better results. The Gravity field and steady-state Ocean Circulation Explorer (GOCE) has been orbiting Earth since March 2009, reaching its ambitious objective to map our planet´s gravity with unrivalled precision. Although the planned mission has been completed, the fuel consumption was much lower than anticipated because...

Atomic Clocks May Survey Earth's Insides
2012-11-12 15:17:48

Lee Rannals for redOrbit.com - Your Universe Online Scientists say they are planning to use portable atomic clocks to help identify mineral deposits and concealed water resources inside the Earth. An international team believes that atomic clocks could already have reached the necessary degree of precision to be useful for geophysical surveying. They said that these clocks will provide the most direct measurement of the geoid, which is the Earth's true physical form. The Earth's...

How much ice is Greenland is really losing? - Movement in the Earth's mantle? - Enough water for all? For the first time, the melting of glaciers in Greenland could now be measured with high accuracy from space. Just in time for the tenth anniversary of the twin satellites GRACE (Gravity Recovery and Climate Experiment) a sharp image has surface, which also renders the spatial distribution of the glacial melt more precisely. The Greenland ice shield had to cope with up to 240 gigatons of...

A team working with Europe's GOCE satellite has shed light on the way the Earth looks from a gravitational point of view. Scientists use the data gathered by the space probe to show how gravity varies across the Earth. The data has revealed how the oceans are moving and how they redistribute the heat from the Sun around the world. GOCE has also helped scientists understand that the earthquakes that struck Japan last month and Chile last year occurred because of huge masses of rock that...

ESA's GOCE satellite has reached its ambitious goal of mapping Earth's gravity with unprecedented precision. In two short years, the sophisticated satellite has collected the measurements needed to record the 'geoid' reference shape of our planet. "GOCE is one of ESA's most innovative missions. The number of 'firsts' it embodies led to many challenges for our scientists, engineers and more than 40 companies involved in building the satellite," said Volker Liebig, Director of ESA's Earth...


Word of the Day
