The mound in the center of this Mars Reconnaissance Orbiter image appears to have blocked the path of the dunes as they marched south (north is to the left in this image) across the scene. Smaller dunes run perpendicular to some of the larger-scale dunes, probably indicating a shift in wind directions in this area. (More at NASA Picture of The Day)
Robotics Work on Space Station Set Up Thursday Spacewalk
The Pressurized Mating Adapter-3 (PMA-3) is in the grip of the International Space Station's Canadarm2 robotic arm during its relocation and attachment to the station's Harmony module on March 26,2017. A spacewalk by NASA astronauts Shane Kimbrough and Peggy Whitson, which began at 7:29 a.m., will finalize the PMA-3 cable connections on Harmony. (More at NASA Picture of The Day)
Dr. Nancy Grace Roman is shown with a model of the Orbiting Solar Observatory (OSO) in 1962. She was the first Chief of Astronomy in the Office of Space Science at NASA Headquarters and the first woman to hold an executive position at NASA.
