NASA Quesst

NASA's Quesst mission, which features the one-of-a-kind X-59 aircraft, will demonstrate technology to fly supersonic, or faster than the speed of sound, without generating loud sonic booms. NASA will then survey how people respond when the X-59 flies overhead, sharing these reactions to the quieter sonic "thumps" with national and international regulators to inform the establishment of new data-driven acceptable noise thresholds related to supersonic commercial flight over land. Quesst is supported through NASA’s Aeronautics Research Mission Directorate.

    NASA’s X-59 Undergoes Scheduled Maintenance

    Workers examine the wing area of the X‑59 aircraft inside a hangar.

    After completing a series of initial test flights at high and low altitudes, NASA’s X-59 aircraft is undergoing a scheduled maintenance period inside its hangar. Teams at NASA’s Armstrong Flight Research Center in Edwards, California, have removed panels on the aircraft to take a better look inside. This allows for thorough visual inspections to confirm […]

    NASA’s X-59 Team Testing Aircraft Performance at All Speeds

    NASA’s X-59 quiet supersonic research aircraft flies above NASA’s Armstrong Flight Research Center and Rogers Dry Lake in California. The aircraft is shown in side profile during level flight with the compass rose, facilities, and desert terrain below.

    Although NASA’s X-59 is designed to fly supersonic, its test flight schedule is about more than just going gradually faster and higher – sometimes, to make sure the aircraft is fully mission-ready, slower and lower is the way to go. The X-59 has completed initial test flights at high altitudes and near-supersonic speeds, opening the […]

    NASA’s X-59 Flight Tests Pick Up Speed with Two-Flight Days

    NASA’s X-59 quiet supersonic research aircraft flies above the Mojave Desert on a clear day. The aircraft is white with light gray, red, and blue accent colors. A NASA logo is visible on its tail, along with the number 859 above it.

    As flight operations for NASA’s quiet supersonic X-59 aircraft accelerate, its team has picked up their testing tempo, completing two test flights in a single day for the first time. The first dual-flight day was on April 30 at NASA’s Armstrong Flight Research Center in Edwards, California. Making its 11th and 12th flights, the X-59 […]
