Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s X-59 lights up the night sky with its unique Mach diamonds, also known as shock diamonds, during maximum afterburner testing at Lockheed Martin Skunk Works in Palmdale, California. The test demonstrated the engine’s ability to generate the thrust required for supersonic flight, advancing NASA’s Quesst mission.Credit: Lockheed Martin/Gary Tice NASA’s X-59 quiet supersonic research aircraft took another successful step toward flight with the conclusion of a series of engine performance tests.
In preparation for the X-59’s planned first flight this year, NASA and Lockheed Martin successfully completed the aircraft’s engine run tests in January. The engine, a modified F414-GE-100 that powers the aircraft’s flight and integrated subsystems, performed to expectations during three increasingly complicated tests that ran from October through January at contractor Lockheed Martin’s Skunk Works facility in Palmdale, California.
“We have successfully progressed through our engine ground tests as we planned,” said Raymond Castner, X-59 propulsion lead at NASA’s Glenn Research Center in Cleveland. “We had no major showstoppers. We were getting smooth and steady airflow as predicted from wind tunnel testing. We didn’t have any structural or excessive vibration issues. And parts of the engine and aircraft that needed cooling were getting it.”
The tests began with seeing how the aircraft’s hydraulics, electrical, and environmental control systems performed when the engine was powered up but idling. The team then performed throttle checks, bringing the aircraft up to full power and firing its afterburner – an engine component that generates additional thrust – to maximum.

The engine produces as much as 22,000 pounds of thrust to achieve a desired cruising speed of Mach 1.4 (925 miles per hour) at an altitude of approximately 55,000 feet.
The X-59’s engine, similar to those aboard the U.S. Navy’s F-18 Super Hornet, is mounted on top of the aircraft to reduce the level of noise reaching the ground. Many features of the X-59, including its 38-foot-long nose, are designed to lower the noise of a sonic boom to that of a mere “thump,” similar to the sound of a car door slamming nearby.
Next steps before first flight will include evaluating the X-59 for potential electromagnetic interference effects, as well as “aluminum bird” testing, during which data will be fed to the aircraft under both normal and failure conditions. A series of taxi tests and other preparations will also take place before the first flight.
The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to commercial supersonic flight over land by making sonic booms quieter.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Local creators representing food, tourism, apparel, and professional sports industries tour several of NASA Glenn Research Center’s facilities. They stop to pose in the Aero-Acoustic Propulsion Laboratory, a world-class facility for conducting aero-propulsion noise reduction research. Credit: NASA/Sara Lowthian-Hanna NASA’s Glenn Research Center has made contributions to nearly every NASA mission since the agency’s inception. These contributions go beyond science and engineering to include designing NASA’s iconic logo. Affectionally called the “meatball,” it was created in Cleveland at the lab that would become NASA Glenn by graphic artist James Modarelli.
This timeless brand symbol turned 65 last month. In honor of the occasion, NASA Glenn’s Office of Communications (OCOMM) hosted a Cleveland Creators Tour on July 10 and welcomed creators representing food, tourism, apparel, and professional sports industries to the center. During the event, they learned about NASA Glenn’s work and ways they can appropriately use NASA’s iconic logo. Like Modarelli, their creative interpretations could engage a new generation of creators, explorers, and space lovers.

Tours of several Glenn research facilities highlighted how Cleveland is improving flight and exploring space.

A NASA logo-themed cake serves as a centerpiece for the event. Credit: NASA/Jef Janis Over 4,300 visitors joined in the fun to commemorate the 65th birthday of NASA’s iconic logo on July 15 at Great Lakes Science Center (GLSC) in downtown Cleveland.
The birthday celebration featured a cake-cutting ceremony and special NASA activities throughout the day, including presentations from NASA’s Glenn Research Center photographers and videographers, a talk from a NASA librarian on the history of the logo, photo opportunities with Glenn’s Eva the Astronaut mascot, a coloring contest, a performance by the NASA Glenn Band, live science shows, and more.

The iconic symbol, known affectionately as “the meatball,” was developed at NASA’s Lewis Research Center in Cleveland (now called NASA Glenn). Employee James Modarelli, who started his career at the center as an artist and technical illustrator, was its chief designer.
