Space Laser To Collect Earth Elevation Data During ICESat-2 Mission
2014-06-04 06:26:59

redOrbit Staff & Wire Reports - Your Universe Online The laser instrument component of NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) is currently being integrated and tested at the Goddard Space Flight Center in Maryland, US space agency officials announced on Tuesday. The instrument, which is known as the Advanced Topographic Laser Altimeter System (ATLAS), will be used to measure the elevation of the planet’s surfaces, including forests, oceans and even ice...

NASA IceBridge Wraps Up Arctic Field Campaign
2014-05-29 03:43:26

By George Hale, NASA Starting With Sea Ice IceBridge's campaign began on Mar. 10 when NASA's P-3 research aircraft left Wallops for Thule. For the first part of the campaign, researchers studied Arctic sea ice from Thule and Fairbanks, Alaska. Early in each campaign IceBridge spends a week in Alaska to survey sea ice north of Alaska. In addition, researchers study sea ice conditions across the entire Arctic Basin traveling from Thule to Fairbanks and back. IceBridge's sea ice...

NASA Study Points To Infrared-Herring As Cause Of Apparent Amazon Green-Up
2014-02-07 10:42:54

Kathryn Hansen, NASA For the past eight years, scientists have been working to make sense of why some satellite data seemed to show the Amazon rainforest "greening-up" during the region's dry season each year from June to October. The green-up indicated productive, thriving vegetation in spite of limited rainfall. Now, a new NASA study published today in the journal Nature shows that the appearance of canopy greening is not caused by a biophysical change in Amazon forests, but instead...

NASA's New Laser Technology Tracks Arctic Ice With Precision
2014-01-29 06:52:00

April Flowers for redOrbit.com - Your Universe Online Flying over Greenland and the Arctic Ocean in April 2012, a high-altitude aircraft completed the first polar test of a new laser-based technology designed to measure the height of Earth from space. That instrument was the Multiple Altimeter Beam Experiment Lidar (MABEL), an airborne test bed instrument designed for NASA's ICESat-2 mission, which is slated for launch in 2017. MABEL has returned new results demonstrating that a...

redOrbit Staff & Wire Reports - Your Universe Online The arrival of NASA scientists and aircraft at McMurdo Station in Antarctica on Saturday marks the beginning of the 2013 Operation IceBridge field campaign in that region, the US space agency has announced. As part of the mission, daily survey flights will take place through November 26 on a NASA P-3 research aircraft departing from a base of operations at the National Science Foundation (NSF) facility. Researchers traveling on...

NASA Airborne Campaign To Measure Summer Melt Of Greenland Ice Sheet
2013-10-31 12:14:26

[ Watch The Video: 5 Questions About LVIS & IceBridge ] NASA For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt. NASA's C-130 research aircraft flew from the Wallops Flight Facility in Wallops Island, Va., to Greenland on Wednesday where they will conduct survey flights to collect data that will improve our understanding of seasonal melt and...
