University of Colorado at Boulder undergraduates, who have been helping to control five NASA satellites from campus, participated in the unusual decommissioning of a functioning satellite with a failed science payload in recent days, bringing the craft into Earth re-entry to burn up yesterday. The satellite, known as the Ice, Cloud and Land Elevation Satellite, or ICESat, orbited Earth for seven years, gathering valuable data on the polar regions and helping scientists develop a better...

UPDATE: NASA's Orbital Debris Program Office at Johnson Space Center, Houston, has reported that debris from the ICESat spacecraft fell to Earth in the Barents Sea on Monday, Aug. 30, at approximately 5 a.m. EDT. One of NASA's orbiting sentinels is expected to return to Earth in a few days. The agency's Ice, Cloud, and land Elevation (ICESat) satellite completed a very productive scientific mission earlier this year. NASA lowered the satellite's orbit last month and then decommissioned the...

Using NASA satellite data, scientists have produced a first-of-its kind map that details the height of the world's forests. Although there are other local- and regional-scale forest canopy maps, the new map is the first that spans the entire globe based on one uniform method. The work -- based on data collected by NASA's ICESat, Terra, and Aqua satellites -- should help scientists build an inventory of how much carbon the world's forests store and how fast that carbon cycles through...

WASHINGTON, July 20 /PRNewswire-USNewswire/ -- Scientists have produced a first-of-its kind map of the height of the world's forests by combining data from three NASA satellites. The map will help scientists build an inventory of how much carbon the world's forests store and how fast that carbon cycles through ecosystems and back into the atmosphere.

NASA-funded researchers monitoring Greenland's Jakobshavn Isbrae glacier report that a 7 square kilometer (2.7 square mile) section of the glacier broke up on July 6 and 7. The calving front "“ where the ice sheet meets the ocean "“ retreated nearly 1.5 kilometers (a mile) in one day and is now further inland than at any time previously observed. The chunk of lost ice is roughly one-eighth the size of Manhattan Island, New York. Research teams led by Ian Howat of the Byrd Polar...

Taking advantage of NASA's 'Operation Ice Bridge' campaign, measurements of Arctic sea ice have been made from an aircraft flying directly under CryoSat-2's orbital path. These measurements offer an early opportunity to check the quality of the newly launched CryoSat-2 satellite data over sea ice. Following the launch of ESA's CryoSat-2 ice mission April 8, the satellite's Synthetic Aperture Interferometric Radar Altimeter (SIRAL) was switched on and delivered its first radar echo data on...

NASA's Operation IceBridge mission, the largest airborne survey ever flown of Earth's polar ice, kicks off its second year of study when NASA aircraft arrive in Greenland March 22. The IceBridge mission allows scientists to track changes in the extent and thickness of polar ice, which is important for understanding ice dynamics. IceBridge began in March 2009 as a means to fill the gap in polar observations between the loss of NASA's Ice, Cloud and land Elevation Satellite, or ICESat, and the...

Tropical forest loss accounts for an estimated 17% of global emissions of carbon dioxide. As part of a strategy to reduce these greenhouse gas fluxes to the atmosphere, the UNFCCC's Conference of the Parties 15 in Copenhagen is working to adopt a strategy for Reducing Emissions from Deforestation and Forest Degradation (REDD) in the post-Kyoto climate treaty. For tropical nations to be effective in tracking and reporting their emissions reductions from forest management and conservation,...

WASHINGTON, Oct. 8 /PRNewswire-USNewswire/ -- NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions.
