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.
