NASA Data Peers into Greenland’s Ice Sheet

Peering into the thousands of frozen layers inside Greenland’s ice sheet is like looking back in time. Each layer provides a record of what Earth’s climate was like at the dawn of civilization, or during the last ice age, or during an ancient period of warmth similar to the one we experience today.

NASA: Alaska Shows No Signs of Rising Arctic Methane

his photo taken during the CARVE experiment shows polygonal lakes created by melting permafrost on Alaska's North Slope. As the frozen soil melts, it shrinks, leaving cracks that fill with water. In winter the water-filled cracks freeze into ice wedges.

Despite large temperature increases in Alaska in recent decades, a new analysis of NASA airborne data finds that methane is not being released from Alaskan soils into the atmosphere at unusually high rates, as recent modeling and experimental studies have suggested. The new result shows that the changes in this part of the Arctic have not yet had enough impact to affect the global methane budget.

It's Alive! Ames Engineers Harvest and Print Parts for New Breed of Aircraft

3-D printed wing part for the FrankenEye aircraft.

It's more an engineer's dream than nightmare - to rapidly prototype and redesign aircraft using 3-D printed parts. That's just what a team of student interns and engineers at NASA's Ames Research Center in Moffett Field, California, got to do: custom-build aircraft by repurposing surplus Unmanned Aerial Vehicles (UAVs). Grafting fuselages side-by-side adds more motors, propellers and batteries to improve power and performance capacity. By lengthening the wings, the team was able to improve aerodynamic efficiency and help extend the flight time of small, lightweight electric aircraft.
