NASA: Alaska Shows No Signs of Rising Arctic Methane
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
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.
NASA Begins Sixth Year of Airborne Antarctic Ice Change Study
NASA is carrying out its sixth consecutive year of Operation IceBridge research flights over Antarctica to study changes in the continent’s ice sheet, glaciers and sea ice. This year’s airborne campaign, which began its first flight Thursday morning, will revisit a section of the Antarctic ice sheet that recently was found to be in irreversible decline.
ARISE Researchers Close out Alaska Field Campaign
Data from ARISE will help scientists understand the relationship between ocean and ice surfaces and clouds and the role that relationship plays in the overall climate system. In addition, ARISE data will help researchers further improve methods of interpreting satellite data in the Arctic.
