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...

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...

Variations Of Gravity Much Larger Than Previously Thought
2013-09-05 10:50:45

[ Watch The Video - GGMplus Earth Gravity Field Model ] Curtin University A joint Australian-German research team led by Curtin University’s Dr Christian Hirt has created the highest-resolution maps of Earth’s gravity field to date – showing gravitational variations up to 40 per cent larger than previously assumed. Using detailed topographic information obtained from the US Space Shuttle, a specialist team including Associate Professor Michael Kuhn, Dr Sten Claessens and Moritz...

Space Seismometer Recorded Japan's 2011 Earthquake, Two Years Ago Today
2013-03-11 14:58:19

WATCH VIDEO: [Earthquake Sensed By GOCE] Lee Rannals for redOrbit.com — Your Universe Online Two years ago today, Japan was rocked by a 9.0-magnitude earthquake and giant tsunami that caused both death and destruction throughout the country. Now, with instrument's like the European Space Agency's (ESA) GOCE satellite, scientists will be able to understand a bit more about these devastating quakes and how they rock Earth. ESA launched the hyper-sensitive GOCE gravity satellite...

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...

Gravity Satellite Will Benefit Future Missions
2012-07-20 15:21:31

ESA´s GOCE satellite is not only mapping Earth´s gravity with unrivalled precision, but is also revealing new insight into air density and wind in space. This additional information is expected to improve the design and operation of future Earth observation missions. Most satellites orbit Earth higher than 400 km. Lower than that and atmospheric drag causes them to slow down quickly and reenter the atmosphere prematurely. This posed a problem for the designers of the GOCE...

Satellites Stay Current On Ocean Currents
2012-05-04 03:09:15

Satellites offer a frequent overview of our entire planet — covered mostly by water — and provide valuable data to monitor and understand global ocean circulation. Understanding water currents at the ocean surface is important for many applications. Ocean surface currents have long fascinated oceanographers as they work to understand the role of oceans in the Earth system and how they affect our climate. Measurements of ocean surface currents are fundamental to a number of...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
