Keeping An Eye – From The Sky – On Volcanoes
2012-03-28 03:43:40

The importance of global and frequent data coverage of volcanoes was highlighted in a recent article published in Science. Satellites are finding that volcanoes previously thought to be dormant are showing signs of unrest. As the 2010 eruption of Eyjafjallajökull in Iceland demonstrated, volcanic eruptions can have consequences over large regions, so the global perspective offered by satellite systems is vital for monitoring volcanoes in remote and inaccessible terrain....

Image 1 - Satellites Map Earth’s Vital Resources
2012-03-23 03:34:25

Recent studies show that satellite radar data can be exploited to map forest height, 3D forest structure and their natural or anthropogenic disturbance with high spatial resolution and accuracy. Since forests assist in removing carbon dioxide from the atmosphere, this could prove to be an important tool for assessing carbon stocks and monitoring our planet´s resources. Polarimetric InSAR — or Pol-InSAR — is a remote sensing technique based on polarimetric information in...

Envisat Celebrates 10th Birthday
2012-03-01 10:28:16

[ Watch the Video ] In the early hours of 1 March 2002, the largest Earth observation satellite ever built soared into orbit from ESA´s launch base in Kourou, French Guiana. For a decade, Envisat has been keeping watch over our planet. The eight-ton satellite has doubled its planned five-year lifetime, circling Earth more than 50 000 times. With ten sophisticated optical and radar sensors, the satellite is continuously observing and monitoring Earth´s land, atmosphere,...

NASA Science Aircraft To Travel The Globe In 2012
2012-02-14 04:49:51

With missions scheduled throughout the year, 2012 is shaping up to be an extraordinary time for NASA´s Airborne Science Program and Earth system science research. Multiple aircraft and specialized instruments will operate in the United States, Europe, Asia and South America this year in support of studies conducted by NASA and the Earth science community, improving scientists' understanding of our planet. The program maintains a fleet of highly modified aircraft and specialized...

Image 1 - Slight Surface Changes Detected From Space
2011-10-13 08:23:28

Scientists are making advances in the use of satellite data to map changes in Earth´s surface. Subsidence of only millimeters can be detected thanks to advances in technology. The picturesque town of Assisi nestling in central Italy´s rolling hills has, for centuries, drawn tourists, religious pilgrims and lovers of art. But it has also drawn the attention of scientists who see the real weight of its reputation. By exploiting satellite data, they have found that some areas of...

Small satellite manufacturer Surrey Satellite Technology Limited (SSTL) has today announced completion of the development phase of its new low-cost Synthetic Aperture Radar (SAR) satellite system. Called NovaSAR-S, the system offers customers coverage of any spot on Earth in all conditions — seeing through cloud cover across both day and night. The 400-kg NovaSAR-S design combines SSTL´s flight-proven SSTL-300 platform with an innovative S-band SAR payload, developed in...

Attend The ERS Workshop From Your Computer

  Join ESA as it celebrate 20 years of Earth observations by the ERS satellites via live web stream on 27 September. A scientific workshop on the legacy of the two European Remote Sensing missions will be held 13:00—17:30 CEST (11:00—15:30 GMT) at ESRIN, ESA´s center for Earth observation, in Frascati, Italy. Those unable to attend the event can follow the program that covers the ERS history, development, operations and exploitation via live web streaming....

Some of the last images from ESA's ERS-2 satellite have revealed rapidly changing glacial features in Greenland. In its final days, the veteran satellite gave us frequent views of the Kangerdlugssuaq glacier and its advancing ice stream. Before it retired on 6 July, ESA's ERS-2 Earth observation satellite entered an orbit to capture radar images of the same area on the ground every three days, rather than its previous 35-day cycle. Images of the Kangerdlugssuaq glacier in eastern...

After 16 years spent gathering a wealth of data that has revolutionized our understanding of Earth, ESA's veteran ERS-2 satellite is being retired. This pioneering mission has not only advanced science, but also forged the technologies we now rely on for monitoring our planet. ERS-2 was launched in 1995, following its sister, the first European Remote Sensing satellite, which was launched four years earlier. Carrying suites of sophisticated instruments to study the complexities of the...

Endeavour launched from Kennedy Space Center on April 9. 1994 at 7:05 AM EDT and landed at Edwards AFB on April 20 at 9:54 AM PDT. The shuttle orbited 183 times at an altitude of 121 nautical miles at an inclination of 57 degrees and travelled 4.7 million miles. The mission lasted  11 days, 5 hours, 49 minutes, and 30 seconds. The primary payload was the Space Radar Laboratory (SRL-1), located in payload bay; activated by crew and operated by teams on ground. SRL-1 included the Spaceborne...
