Understanding Of China’s Poyang Lake Water Surface Dynamics
2014-06-02 03:10:58

ESA As ESA and China mark a decade of cooperation, imagery over China’s Poyang lake is testament to the new Sentinel satellite’s promise of continued radar data acquisition for a multitude of applications. The Poyang lake in southern China’s Jiangxi province is the largest freshwater lake in the country. This lake is an important habitat for migrating Siberian cranes – many of which spend the winter there. The basin is also one of China's most important rice-producing...

Examining Satellites’ Mysterious Death Tumbling
2014-05-30 03:50:01

ESA Down on the ground, death equals stillness – but not in space. Derelict satellites can tumble in unpredictable ways and ESA’s team tasked with developing a space salvage mission want to find out why. In recent years, satellites beginning uncontrolled reentries have been tracked, such as Russia’s Phobos-Grunt and Germany’s Rosat. In a few cases, satellites suffering unexpected failures in orbit have also been followed, including ESA’s Envisat and Japan’s ADEOS-II. In...

Space Debris Threat From Envisat Explored By University Of Leicester Students
2014-02-20 07:32:18

redOrbit Staff & Wire Reports - Your Universe Online A recently-published paper from physics students at the University of Leicester explores the possibility that a massive observational satellite that lost contact with Earth in 2012 could be the catalyst that sets off a chain of events much like those depicted in the Academy Award-nominated film Gravity. Writing in the Journal of Physics Special Topics, a peer-reviewed student journal run by the University’s Department of Physics...

Could Global Warming Be Hiding Underwater?
2014-02-10 09:17:24

ESA Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result of a rearrangement in the energy flow of the climate system and, in particular, how the ocean stores heat. Like flying thermometers, some satellites carry instruments that provide a global view of the surface temperature of oceans and seas. Measuring the sea-surface temperature...

Winter Ice Is On The Decline Across Alaskan Lakes
2014-02-03 10:22:48

Brett Smith for redOrbit.com - Your Universe Online According to a new study from the European Space Agency, ice in northern Alaska’s lakes during winter months is on the decline. Twenty years of satellite radar images in the study, which was published in The Cryosphere, show how shifts in our climate are affecting high-latitude regions. [ Watch the video: Monitoring Lake Ice ] Alterations in air temperature and winter precipitation over the last 50 years have affected the timing,...

ESA CryoSat Mission Confirms Antarctic Ice Loss Is On The Rise
2013-12-12 06:08:21

Alan McStravick for redOrbit.com - Your Universe Online With news out of San Francisco this week, at the autumn meeting of the American Geophysical Union (AGU), we learned scientists have incorrectly estimated the amount of ice being lost on the polar continent of Antarctica. This environmental faux pas directly affects the estimates on global sea level rise as well. The team presenting these findings conducted their research with the Natural Environment Research Council’s Center for...

Satellite Flood Maps Reach Crisis Teams Through The Internet
2013-09-27 12:09:40

ESA Building on its use of satellites for responding to disasters, ESA has helped to create a service that makes flood maps available simply via the Internet. Floods can be devastating, as seen recently in Germany and central Europe. Knowing the extent of a flood and understanding how it might develop is essential for teams responding to the emergency. Traditionally, this is often worked out using ground and airborne sensors along with historical flood maps. Invariably, these...

CO2 On The Rise Satellite Images
2013-09-04 13:04:37

Lee Rannals for redOrbit.com - Your Universe Online A new report says satellite observations have shown that carbon dioxide in our atmosphere has continued to increase, despite global efforts to curb emissions. Ten years of data taken from the European Space Agency's (ESA) Envisat mission and Japan's Greenhouse gases Observing Satellite (GOSAT) show that carbon dioxide increased by about 0.5 percent every year between 2003 and 2013. The measurements also show that methane began...

Jason-1 Satellite Decommissioned
2013-07-03 14:48:04

Michael Harper for redOrbit.com - Your Universe Online More than 11 years ago, NASA launched the Jason-1 ocean altimetry satellite into orbit in a joint venture with the Centre National d'Etudes Spatiales (CNES). The satellite would be used to map sea levels, wave height and wind speed from miles above the ocean's surface. Since that time, one successor satellite, the Jason-2, has been sent into space to supplement this information. The Jason-3 is expected to launch in 2015. Two weeks...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
