This Week at NASA: Mars, Orion, CubeSat’s and More

NASA’s Curiosity rover is making an unscheduled stop on its way up Mount Sharp on Mars, for a close-up look at a collection of actively moving sand dunes.
Images from orbit indicate that the Bagnold Dunes are migrating as much as about 3 feet per Earth year, and includes one particular dune that is about two-stories high and as broad as a football field. Researchers plan to have the rover take samples for analysis. No active dunes have ever been visited anywhere else in the solar system besides Earth. Also, Orion cone panels welded, Launch approaches for Cygnus, Student CubeSat onboard Cygnus, New crew access tower components and more.
