(Little Joe is a dice players slang term for two deuces.) Walker is shown in the photo wearing an early Air Force partial pressure suit. This protected the pilot if cockpit pressure was lost above 50,000 feet. Similar suits were used in such aircraft as B-47s, B-52s, F-104s, U-2s, and the X-2 and D-558-II research aircraft. Five years later, Walker reached 354,200 feet in the X-15. Similar artwork - reading "Little Joe the II" - was applied for the record flight. These cases are two of the few times that research aircraft carried such nose art.

“I’m a big community person. I’m a person who will be like, ‘I think I know someone for you.’ And then I’ll put everyone together. So I’m a big person on lending a helping hand. My platform is for highlighting folks. I’ve highlighted over 50 black junior astronomers for Black History Month, which I will continuously do. I founded the #BlackInAstro Week, which was very successful. I had no clue it was even trending until other people told me. I didn’t even realize until it was the middle of the week, and people were saying, ‘congratulations!’ And I was like, ‘wait, what? Okay, thanks!’ I didn’t realize it was that big. “Community for me and using my platform to promote others — it’s something that really makes me happy. It’s very important to lift others up because for me, I don’t see people who look like me. You never know who’s watching, or who will get inspired. The next generation of scientists will be amazing. This generation of scientists is outstanding — but the next generation will be amazing, so on and so forth. We’re just going to keep lifting each other up and making sure that we all have each other’s backs, because right now is a critical time in our lives. We need each other more than anything.” Ashley Walker, Intern in the Undergraduate Research Associates in Astrobiology program at NASA’s Goddard Space Flight Center, is photographed in her home in Chicago, Ill. via video conference, Saturday, July 25, 2020 in Alexandria, Va.

Joseph A. Walker was a Chief Research Pilot at the NASA Dryden Flight Research Center during the mid-1960s. He joined the NACA in March 1945, and served as project pilot at the Edwards flight research facility on such pioneering research projects as the D-558-1, D-558-2, X-1, X-3, X-4, X-5, and the X-15. He also flew programs involving the F-100, F-101, F-102, F-104, and the B-47. Walker made the first NASA X-15 flight on March 25, 1960. He flew the research aircraft 24 times and achieved its fastest speed and highest altitude. He attained a speed of 4,104 mph (Mach 5.92) during a flight on June 27, 1962, and reached an altitude of 354,300 feet on August 22, 1963 (his last X-15 flight). He was the first man to pilot the Lunar Landing Research Vehicle (LLRV) that was used to develop piloting and operational techniques for lunar landings. Walker was born February 20, 1921, in Washington, Pa. He lived there until graduating from Washington and Jefferson College in 1942, with a B.A. degree in Physics. During World War II he flew P-38 fighters for the Air Force, earning the Distinguished Flying Cross and the Air Medal with Seven Oak Clusters. Walker was the recipient of many awards during his 21 years as a research pilot. These include the 1961 Robert J. Collier Trophy, 1961 Harmon International Trophy for Aviators, the 1961 Kincheloe Award and 1961 Octave Chanute Award. He received an honorary Doctor of Aeronautical Sciences degree from his alma mater in June of 1962. Walker was named Pilot of the Year in 1963 by the National Pilots Association. He was a charter member of the Society of Experimental Test Pilots, and one of the first to be designated a Fellow. He was fatally injured on June 8, 1966, in a mid-air collision between an F-104 he was piloting and the XB-70.

Cabana, Pilot; and Michael R. (Rick) Clifford, mission specialist. The crew launched aboard the Space Shuttle Discovery on December 2, 1992 at 8:24:00 am (EST). This mission marked the final classified shuttle flight for the Department of Defense (DOD).

Five astronauts composed the STS-30 crew. Pictured (left to right) are Ronald J. Grabe, pilot; David M. Walker, commander; and mission specialists Norman E. Thagard, Mary L. Cleave, and Mark C. Lee. The STS-30 mission launched aboard the Space Shuttle Atlantis on May 4, 1989 at 2:46:59pm (EDT). The primary payload was the Magellan/Venus Radar mapper spacecraft and attached Inertial Upper Stage (IUS).

These five NASA astronauts were the crew members for the STS-69 mission that launched aboard the Space Shuttle Endeavour September 7, 1995. Pictured on the front row (left to right) are David M. Walker, mission commander; and Kenneth D. Cockrell, pilot. On the back row (left to right) are Michael L. Gernhardt and James H. Newman, both mission specialists; and James S. Voss, payload commander. The mission’s two primary payloads included the Spartan 201-3 and Wake Shield Facility-2 (WSF-2).
