The X-59, NASA’s quiet supersonic technology experimental aircraft, arrives back at Lockheed Martin’s Skunk Works facility in Palmdale, California, following several months of critical ground testing in Ft. Worth, Texas

NASA’s X-59 towbar sits in front of a hangar at NASA’s Armstrong Flight Research Center in Edwards, California. Because of the aircraft’s long nose, a long towbar is required, and it is positioned on the tarmac awaiting the X-59’s arrival ahead its first flight.

One of multiple microphone stations used in the CarpetDIEM flight series, which gave researchers valuable lessons learned in preparations to deploy a similar array for the quiet supersonic X-59. Prior to community overflights, X-59 will undergo an acoustic validation phase, during which NASA will deploy the array of specially-configured microphones to measure the X-59’s thumps, in order to verify that they are as quiet as predicted.

NASA’s X-59 quiet supersonic research aircraft successfully completed electromagnetic interference (EMI) testing at Lockheed Martin Skunk Works in Palmdale, California. During EMI tests, the team examined each of the X-59’s internal electronic systems, ensuring they worked with one another without interference. The X-59 is designed to fly faster than the speed of sound while reducing the loud sonic boom to a quieter sonic thump.

This overhead view of the X-59 shows the aircraft’s current state of assembly at Lockheed Martin Skunk Works in Palmdale, California. Throughout the manufacturing process, the team often removes components to effectively and safely assemble other sections of the aircraft. The X-59’s horizontal tails and lower empennage were recently removed from the aircraft and can be seen behind it as the team prepares for the installation of the engine. The X-59 is the centerpiece of the Quesst mission which plans to help enable commercial supersonic air travel over land.

This cutaway drawing shows the S-IVB (third stage) of the Saturn V launch vehicle. As a part of the Marshall Space Flight Center’s (MSFC) “building block” approach to the Saturn development, the S-IVB stage was utilized in the Saturn IB launch vehicle as a second stage and, later, the Saturn V launch vehicle as a third stage. The 59 foot long and 22 feet diameter stage was powered by a single J-2 engine, initially capable of 200,000 pounds of thrust.

Docking occurred at 3:59 p.m. (CST) on November 25, 2002. The Port One (P1) truss, which was later to be attached to the station and outfitted during three spacewalks, can be seen in Endeavour’s cargo bay.

NASA’s 2017 astronaut candidates (L to R) Jessica Watkins, Jenni Sidey-Gibbons, Joshua Kutryk, and Jasmin Moghbeli practice flying in an F-18 aircraft cockpit simulator at Armstrong Flight Research Center, in Southern California.

STS059-S-107 (20 April 1994) --- The main landing gear of the Space Shuttle Endeavour touches down at Edwards Air Force Base to complete the 11-day STS-59/SRL-1 mission. Landing occurred at 9:54 a.m. (PDT), April 20, 1994. Mission duration was 11 days, 5 hours, 49 minutes. Guiding Endeavour to a landing was astronaut Sidney M. Gutierrez, STS-59 commander. His crew was Kevin P. Chilton, Linda M. Godwin, Jerome (Jay) Apt, Michael R. (Rich) Clifford and Thomas D. Jones.

STS059-S-108 (20 April 1994) --- The main landing gear of the Space Shuttle Endeavour touches down at Edwards Air Force Base to complete the 11-day STS-59/SRL-1 mission.

STS032-S-069 (9 Jan. 1990) --- The space shuttle Columbia, with a five member crew aboard, lifts off for the ninth time as STS-32 begins a 10-day mission in Earth orbit. Leaving from Launch Pad 39A at 7:34:59:98 a.m. EST, in this horizontal (cropped 70mm) frame, Columbia is seen reflected in nearby marsh waters some 24 hours after dubious weather at the return-to-launch site (RTLS) had cancelled a scheduled launch. Onboard the spacecraft were astronauts Daniel C. Brandenstein, James D. Wetherbee, Bonnie J. Dunbar, G. David Low and Marsha S. Ivins. Photo credit: NASA
