The space agency is launching these missions at a time when decades of observations from the ground, air, and space have revealed signs of change in Earth’s ice sheets, sea ice, glaciers, snow cover and permafrost. Collectively, scientists call these frozen regions of our planet the “cryosphere.” ![]() In 2018, NASA is scheduled to launch two new satellite missions and conduct an array of field research that will enhance our view of Earth’s ice sheets, glaciers, sea ice, snow cover, and permafrost. Collectively, these frozen regions are known as the “cryosphere.” (NASA) «Read the rest of this article» Sections: Technology | No Comments
Dinosaur Footprints found at NASA’s Goddard Space Flight CenterWritten by Ashley Hume and Patrick Lynch
The tracks were discovered by Ray Stanford — a local dinosaur track expert whose wife, Sheila, works at Goddard. After dropping off Sheila at work one day in 2012, Stanford spotted an intriguing rock outcropping behind Shelia’s building on a hillside. Stanford parked his car, investigated, and found a 12-inch-wide dinosaur track on the exposed rock. ![]() A model of a Nodosaur dinosaur sits inside what is believed to be the fossil of a Nodosaur footprint. The footprint was found by Ray Stanford a local dinosaur hunter. (NASA/Goddard/Rebecca Roth) «Read the rest of this article» Sections: Technology | No Comments
NASA measurements show Ethanol Refineries Emissions may be higher than EstimatedWritten by Patrick Lynch
Airborne measurements made downwind from an ethanol fuel refinery in Decatur, Illinois, in 2013 found ethanol emissions 30 times higher than government estimates. The measurements also showed emissions of all volatile organic compounds (VOCs), which include ethanol, were five times higher than government numbers, which estimate emissions based on manufacturing information. ![]() Air-quality readings over the Midwest were made from an aircraft in 2013 at three different distances downwind from an ethanol refining plant in Decatur, Illinois. The measurements were used to calculate emissions of various gases, including VOCs, nitrogen oxides and sulfur dioxide.

West Antarctic Ice Sheet unstoppable loss not unexpected by NASA ScientistsWritten by Patrick Lynch
The study, led by glaciologist Eric Rignot at NASA’s Jet Propulsion Laboratory, Pasadena, California, and the University of California, Irvine, follows decades of research and theory suggesting the West Antarctic Ice Sheet is inherently vulnerable to change. ![]() Although the Amundsen Sea region is only a fraction of the whole West Antarctic Ice Sheet, the region contains enough ice to raise global sea levels by 4 feet (1.2 meters).

Watching the Birth of an IcebergWritten by Patrick Lynch
NASA’s Operation IceEarth Bridge, the largest airborne survey of Earth’s polar ice ever flown, is in the midst of its third field campaign from Punta Arenas, Chile. The six-year mission will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice. ![]() NASA's Operation Ice Bridge discovers an emerging crack that cuts across the ice shelf of Pine Island Glacier.

NASA Continues Critical Survey of Antarctica’s Changing IceSteve Cole – Headquarters, Washington, D.C.
Researchers are flying a suite of scientific instruments on two planes from a base of operations in Punta Arenas, Chile: a DC-8 operated by NASA and a Gulfstream V (G-V) operated by the National Science Foundation and the National Center for Atmospheric Research. The G-V will fly through early November. The DC-8, which completed its first science flight October 12th, will fly through mid-November. ![]() NASA’s Operation IceBridge mission comprises the largest airborne research campaign ever flown over Earth’s polar region. The mission is designed to continue critical ice sheet measurements in a period between active satellite missions and help scientists understand how much the major ice sheets of Greenland and Antarctica could contribute to sea level rise.
