ISS002-422-025 (13 July 2001) --- Partially obscured by the Canadarm2, or Space Station Remote Manipulator System (SSRMS), arm the Space Shuttle Atlantis (background) moves toward the International Space Station (ISS) during rendezvous operations. Atlantis commander Steven W. Lindsey smoothly docked the shuttle with the orbiting outpost about 240 statute miles above the northeastern coast of South America. With both spacecraft moving at about 17,500 mph, Lindsey moved Atlantis to the station at a relative speed of about a tenth of a foot per second. Docking occurred at 10:08 p.m. (CDT), July 13, 2001. Atlantis brought to the station a new airlock, called Quest, which can be seen in the aft cargo bay.

NASA's F-15B Aeronautics Research Test Bed performs a calibration flight of the shock-sensing probe over Edwards, California, on Aug. 6, 2024. The probe will measure shock waves from NASA's X-59.

Event: Forebody and Nose - Windtunnel Testing A model of the X-59 forebody is shown in the Lockheed Martin Skunk Works’ wind tunnel in Palmdale, California. These tests gave the team measurements of wind flow angle around the aircraft’s nose and confirmed computer predictions made using computational fluid dynamics (CFD) software tools. The data will be fed into the aircraft flight control system to tell the pilot the aircraft’s altitude, speed and angle. This is part of NASA’s Quesst mission which plans to help enable supersonic air travel over land.

NASA’s X-59 quiet supersonic research aircraft flies above Palmdale and Edwards, California, on its first flight Tuesday, Oct. 28, 2025, accompanied by a NASA F-15 research aircraft. The F-15 monitored the X-59 during the flight as it traveled to NASA’s Armstrong Flight Research Center in Edwards, California, where it will begin flight testing for NASA’s Quesst mission, which aims to demonstrate quiet supersonic flight over land.

NASA’s X-59 quiet supersonic research aircraft lifts off for its first flight Tuesday, Oct. 28, 2025, from U.S. Air Force Plant 42 in Palmdale, California. The aircraft’s first flight marks the start of flight testing for NASA’s Quesst mission, the result of years of design, integration, and ground testing and begins a new chapter in NASA’s aeronautics research legacy.

NASA’s X-59 quiet supersonic research aircraft is seen at dawn with firetrucks and safety personnel nearby during a hydrazine safety check at U.S. Air Force Plant 42 in Palmdale, California, on Aug. 18, 2025. The operation highlights the extensive precautions built into the aircraft’s safety procedures for a system that serves as a critical safeguard, ensuring the engine can be restarted in flight as the X-59 prepares for its first flight.

Maintainers perform a hydrazine safety check on NASA’s quiet supersonic X-59 aircraft at U.S. Air Force Plant 42 in Palmdale, California, on Aug. 18, 2025. Hydrazine is a highly toxic chemical, but it serves as a critical backup to restart the engine in flight, if necessary, which is one of several safety features being validated ahead of the aircraft’s first flight.

The X-59 quiet supersonic research aircraft arrives at NASA’s Armstrong Flight Research Center in Edwards, California, following its first flight Tuesday, Oct. 28, 2025. The arrival marks the aircraft’s transition from ground testing to flight operations. Next, the aircraft will undergo scheduled maintenance followed by a series of additional test flights, gradually building toward its first supersonic flight.

NASA test pilot Nils Larson steps out of the X-59 after successfully completing the aircraft’s first flight Tuesday, Oct. 28, 2025. The mission marked a key milestone in advancing NASA’s Quesst mission to enable quiet supersonic flight over land.
