In this March 29, 1929 photograph, Pearl I. Young is working in the Langley Memorial Aeronautical Laboratory's Flight Instrumentation Facility (Building 1202). Young was the first woman hired as a technical employee, a physicist at the National Advisory Committee for Aeronautics and the second female physicist working for the federal government. http://www.nasa.gov/sites/default/files/thumbnails/image/l-03247.jpg
UGC 12591's classification straddles somewhere between a lenticular and a spiral galaxy. It lies just under 400 million light-years from us in the Pisces–Perseus Supercluster. http://www.nasa.gov/sites/default/files/thumbnails/image/potw1709a.jpg
In the Space Station Processing Facility high bay at NASA's Kennedy Space Center in Florida, the Orbital ATK CYGNUS pressurized cargo module is secured the KAMAG transporter and the crane has been removed. http://www.nasa.gov/sites/default/files/thumbnails/image/33133284096_7e0bb60323_o_0.jpg
Viscous, lobate flow features are commonly found at the bases of slopes in the mid-latitudes of Mars, and are often associated with gullies. http://www.nasa.gov/sites/default/files/thumbnails/image/pia21554.jpg

The super star cluster Westerlund 1, only 15,000 light-years away in our Milky Way neighborhood, hosts one of the largest stars ever discovered. http://www.nasa.gov/sites/default/files/thumbnails/image/potw1710a.jpg
Mimas' gigantic crater Herschel lies near the moon's limb in this Cassini view. http://www.nasa.gov/sites/default/files/thumbnails/image/pia20523-1041.jpg
The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite captured this natural-color image of cloud streets over the Barents Sea and Mezhdusharsky Island on March 7, 2017. Such formations occur frequently in the region in late winter. http://www.nasa.gov/sites/default/files/thumbnails/image/barentssea_amo_2017066_lg.jpg
Annie Easley at NASA Glenn Research Center. In 1955, Easley began her career at NASA, then the National Advisory Committee for Aeronautics (NACA), as a human computer performing complex mathematical calculations. http://www.nasa.gov/sites/default/files/thumbnails/image/grc-1981-c-03692.jpg

This view, acquired on Nov. 7, 2016, by the Operational Land Imager (OLI) on Landsat 8, shows a portion of Canada's Mackenzie River Delta and the town of Inuvik, home to more than 3,000 people. A frozen highway -- 194 kilometers (120 miles) long -- runs between the remote outposts of Inuvik and Tuktoyaktuk along the river’s East Channel. http://www.nasa.gov/sites/default/files/thumbnails/image/mackenzie_oli_2016312_lrg.jpg
On April 15, 2002, STS-110 Mission Specialist Ellen Ochoa works at the Remote Manipulator System controls on the aft flight deck of space shuttle Atlantis. Dr. Ochoa, a veteran astronaut, is currently the 11th director of Johnson Space Center. She became the first Hispanic woman to go to space when she served on the STS-56 mission. http://www.nasa.gov/sites/default/files/thumbnails/image/29623539086_d48a0b301f_o.jpg
Hubble spots two interacting galaxies some 60 million light-years away in the constellation of Leo. http://www.nasa.gov/sites/default/files/thumbnails/image/potw1712a.jpg
This enhanced-color image of a mysterious dark spot on Jupiter seems to reveal a Jovian “galaxy” of swirling storms. http://www.nasa.gov/sites/default/files/thumbnails/image/pia21386.jpg
Flight Engineer Thomas Pesquet of ESA is seen floating outside the International Space Station during a spacewalk. Pesquet and Expedition 50 Commander Shane Kimbrough of NASA conducted the six-hour-and-34-minute spacewalk on March 24, 2017. A second spacewalk, by Kimbrough and NASA astronaut Peggy Whitson, is scheduled for Thursday, March 30. http://www.nasa.gov/sites/default/files/thumbnails/image/33531796282_85801ec9ef_o.jpg
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. http://www.nasa.gov/sites/default/files/thumbnails/image/pia21572.jpg
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. http://www.nasa.gov/sites/default/files/thumbnails/image/iss050e060267.jpg
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. She had oversight for the planning and development of programs including the Hubble Space Telescope. http://www.nasa.gov/sites/default/files/thumbnails/image/7538840276_f987be0cb7_o.jpg
