NASA's modified Boeing 747 Shuttle Carrier Aircraft with the Space Shuttle Discovery on top lifts off from Edwards Air Force Base to begin its ferry flight back to the Kennedy Space Center in Florida. The cross-country journey will take two days, with stops at several intermediate points for refueling. Space Shuttle Discovery landed safely at NASA's Dryden Flight Research Center at Edwards Air Force Base in California at 5:11:22 a.m. PDT, August 9, 2005, following the very successful 14-day STS-114 return to flight mission. During their two weeks in space, Commander Eileen Collins and her six crewmates tested out new safety procedures and delivered supplies and equipment the International Space Station. Discovery spent two weeks in space, where the crew demonstrated new methods to inspect and repair the Shuttle in orbit. The crew also delivered supplies, outfitted and performed maintenance on the International Space Station. A number of these tasks were conducted during three spacewalks. In an unprecedented event, spacewalkers were called upon to remove protruding gap fillers from the heat shield on Discovery's underbelly. In other spacewalk activities, astronauts installed an external platform onto the Station's Quest Airlock and replaced one of the orbital outpost's Control Moment Gyroscopes. Inside the Station, the STS-114 crew conducted joint operations with the Expedition 11 crew. They unloaded fresh supplies from the Shuttle and the Raffaello Multi-Purpose Logistics Module. Before Discovery undocked, the crews filled Raffeallo with unneeded items and returned to Shuttle payload bay. Discovery launched on July 26 and spent almost 14 days on orbit.

The aircraft will be used during the development of the low-boom X-59 aircraft that is planned to fly supersonically over land, which is not allowed at this time because of the loud noise created when flying beyond the speed of sound.

NASA DC-8 Ground Support Technician Joe Niquette performs routine maintenance on the DC-8 aircraft at Carlos Ibanez del Campo International Airport in Punta Arenas, Chile. AirSAR 2004 is a three-week expedition by an international team of scientists that is using an all-weather imaging tool, called the Airborne Synthetic Aperture Radar (AirSAR) which is located onboard NASA's DC-8 airborne laboratory. Scientists from many parts of the world including NASA's Jet Propulsion Laboratory are combining ground research done in several areas in Central and South America with NASA's AirSAR technology to improve and expand on the quality of research they are able to conduct. In South America and Antarctica, AirSAR will collect imagery and data to help determine the contribution of Southern Hemisphere glaciers to sea level rise due to climate change. In Patagonia, researchers found this contribution had more than doubled from 1995 to 2000, compared to the previous 25 years. AirSAR data will make it possible to determine whether that trend is decreasing, continuing or accelerating. AirSAR will also provide reliable information on ice shelf thickness to measure the contribution of the glaciers to sea level.

The X-31 Enhanced Fighter Maneuverability Technology Demonstrator Aircraft, based at the NASA Dryden Flight Research Center, Edwards, California, begins rolling aboard an Air Force Reserve C-5 transport which ferried it on May 22, 1995 to Europe where it was flown in the Paris Air Show in June 1995. To fit in the C-5 the right wing of the X-31 had to be removed. At the air show, the X-31 demonstrated the value of using thrust vectoring (directing engine exhaust flow) coupled with advanced flight control systems to provide controlled flight at very high angles of attack.

NASA’s X-59 quiet supersonic research aircraft sits on the ramp during engine run testing on Thursday, March 12, 2026, at NASA’s Armstrong Flight Research Center in Edwards, California. Engine runs are one of the final tests before the aircraft is ready for its second flight. The data collected from the aircraft during upcoming flight tests could help inform future regulations for commercial supersonic travel over land.

Engineers monitor data during vibration testing of a cruise motor controller for the X-57 Maxwell, NASA’s first all-electric X-plane. Attached to a table at NASA Armstrong Flight Research Center’s environmental lab, the cruise motor controller is exposed to specific levels of vibration, allowing NASA to examine the structural integrity of the hardware. Engineers, meanwhile, monitored data, including waveforms of electrical current, and recorded readings.

NASA's Super Guppy Turbine cargo aircraft in the hangar at NASA's Armstrong Flight Research Center on August 24, 2021. This unique whale-like aircraft arrived at the center's Building 703 in Palmdale, CA to support crews in the performance of routine maintenance. The Super Guppy aircraft, operated by NASA's Johnson Space Center, aids in the transportation of oversized aerospace cargo in a practical and economical way.

This rear view shows an F/A-18E from the Naval Air Systems Command (NAVAIR) in Patuxent River, Maryland. The aircraft is in NASA’s Armstrong Flight Research Center Flight Loads Laboratory in Edwards, California, where it underwent the center’s biggest load calibrations tests. This testing will permit the aircraft to serve as a test vehicle to determine if it can safely manage maneuvers and proposed upgrades.
