Lockheed Martin Skunk Works Vice President and General Manager John Clark speaks on stage prior to the unveiling of the agency’s X-59 quiet supersonic research aircraft at a January 12, 2024 event at Lockheed Martin Skunk Works in Palmdale, California. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land, currently banned in the United States, by making sonic booms quieter.

The target beneath the tool turret at the end of the rover's robotic arm in this image from NASA's Mars Exploration Rover Opportunity is "Private John Potts." It lies high on the southern side of "Marathon Valley," which slices through the western rim of Endeavour Crater. The target's informal name refers to a member of the Lewis and Clark Expedition's Corps of Discovery. The image was taken by Opportunity's front hazard avoidance camera on Jan. 5, 2016, during the 4,248th Martian day, or sol, of the rover's work on Mars. This camera is mounted low on the rover and has a wide-angle lens. In this image, the microscopic imager on the turret is pointed downward. Opportunity's examination of this target also used the turret's rock abrasion tool for removing the surface crust and alpha particle X-ray spectrometer for identifying chemical elements in the rock. http://photojournal.jpl.nasa.gov/catalog/PIA20285

KENNEDY SPACE CENTER, FLA. -- STS-95 crew members check out camera equipment they will use on the mission during a SPACEHAB familiarization tour and briefing at the SPACEHAB Payload Processing Facility in Cape Canaveral. Seated, from left, are Payload Specialist John H. Glenn Jr., who also is a senator from Ohio; Pilot Steven W. Lindsey; and Mission Specialist Scott E. Parazynski. Standing in back are Boeing employees LaDonna Neterer and Scott Clark. STS-95 will feature a variety of research payloads, including the Spartan solar-observing deployable spacecraft, the Hubble Space Telescope Orbital Systems Platform, the International Extreme Ultraviolet Hitchhiker, and experiments on space flight and the aging process. STS-95 is targeted for an Oct. 29 launch aboard the Space Shuttle Discovery

Women Scientists: Lucille Coltrane, Jean Clark Keating, Katherine Cullie Speegle, Doris 'Dot' Lee, Ruth Whitman, and Emily Stephens Mueller,Lucille Coltrane is at the far left. She was a computer and worked for Norm Crabill who provided positive identification. Lucille authored a NACA Research Memorandum, Investigation of Two Bluff Shapes in Axial Free Flight Over a Mach Number Range From 0.35 to 2.15 in 1958. Next to Lucille is Jean Clark Keating. Jean was identified by Mary Woerner who said that both Jean and her husband Jerry are now deceased. The third woman from the left is Katherine Cullie Speegle. Katherine co-authored two research papers: Preliminary Results From a Free-Flight Investigation of Boundary-Layer Transition and Heat Transfer on a Highly Polished 8-Inch-Diameter Hemisphere-Cylinder at Mach Numbers up to 3 and Reynolds Numbers Based on a Length of 1 Foot up to 17.7 x 10 to the 6th and Heat Transfer For Mach Numbers Up to 2.2 and Pressure Distributions for Mach Numbers Up to 4.7 From Flight Investigations of a Flat-Face Cone and a Hemisphere-Cone. Norm remembered the woman standing as Doris. Mary Alice identified her as Doris 'Dot' Lee, who worked with Katherine Speegle. Dot was married to a NASA engineer named John Lee. Next to Doris is Ruth Whitman. Norm remembered she and her husband owned a Howard DGA 15 at the airport in WEst Point. That prompted Mary Alice to remember her name and that her husband was Jim. The woman seated on the right is Emily Stephens Mueller. Norm remembers that Emily went to Houston as part of the Space Task Group, but retired back here on the peninsula. In 2008, Emily attended the NACA Reunion X11. She walked over to a table of books about the history of NACA, former NACA facilities and the organization's aviation pioneers and saw a book about women of flight from the Dryden Research Center and paused, then pointed somewhat in amazement. "That’s me," she said of a picture on the cover of her on the far left of a li

In July 2015, NASA's New Horizons spacecraft sent home the first close-up pictures of Pluto and its moons. Using actual New Horizons data and digital elevation models of Pluto and its largest moon, Charon, mission scientists created flyover movies that offer spectacular new perspectives of the many unusual features that were discovered and which have reshaped our views of the Pluto system -- from a vantage point even closer than a ride on New Horizons itself. The flight over Charon begins high over the hemisphere New Horizons saw on its closest approach, then descends over the deep, wide canyon of Serenity Chasma. The view moves north, passing over Dorothy Gale crater and the dark polar hood of Mordor Macula. The flight then turns back south, covering the northern terrain of Oz Terra before ending over the relatively flat equatorial plains of Vulcan Planum and the "moated mountains" of Clarke Montes. (Note that all feature names are informal.) The topographic relief is exaggerated by a factor of 2 to 3 in these movies to emphasize topography; the surface colors have also been enhanced to bring out detail. Digital mapping and rendering were performed by Paul Schenk and John Blackwell of the Lunar and Planetary Institute in Houston.
