AirSAR 2004 Mesoamerica is a three-week expedition by an international team of scientists that uses 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 America with NASA's AirSAR technology to improve and expand on the quality of research they are able to conduct. The radar, developed by NASA's Jet Propulsion Laboratory, can penetrate clouds and also collect data at night. Its high-resolution sensors operate at multiple wavelengths and modes, allowing AirSAR to see beneath treetops, through thin sand, and dry snow pack. AirSAR's 2004 campaign is a collaboration of many U.S. and Central American institutions and scientists, including NASA; the National Science Foundation; the Smithsonian Institution; National Geographic; Conservation International; the Organization of Tropical Studies; the Central American Commission for Environment and Development; and the Inter-American Development Bank.

NASA 862, which is an F/A-18D now based at NASA’s Armstrong Flight Research Center in Edwards, California, arrives for the first time in 2021. The aircraft was stationed at the U.S. Naval Air Station Patuxent River in Maryland. Once here, the aircraft was sent for major maintenance, painting, and preparation to join the NASA Armstrong aircraft fleet.

NASA ground and maintenance crews prepare the F/A-18 research aircraft for a supersonic research flight off the coast of Galveston, Texas in support of the QSF18 flight campaign. These crews are vital to making sure the aircraft is ready to operate safely and efficiently for NASA’s research.

NASA DC-8 Ground Support Technicians Mark Corlew and Mike Lakowski perform routine maintenance on the 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.

CAPE CANAVERAL, Fla. – Space shuttle Discovery is towed through the open doors of NASA Kennedy Space Center's Orbiter Processing Facility 3. In the OPF, turnaround processing procedures on Discovery will include various post-flight deservicing and maintenance functions, which are carried out in parallel with payload removal and the installation of equipment needed for the next mission. Discovery returned to Kennedy atop a Shuttle Carrier Aircraft Sept. 21 after a two-day ferry flight. The piggybacked shuttle and aircraft touched down on the Shuttle Landing Facility's runway 33 at 12:05 p.m. EDT and the shuttle later was demated from the aircraft. Discovery landed at Edwards Air Force Base in California on Sept. 11 after the 13-day STS-128 mission to the International Space Station. Landings at Kennedy were waved off on two days due to inclement weather, leading to the landing at Edwards. Photo credit: NASA/Jack Pfaller

The NASA Fundamental Aeronautics Hypersonics project is focused on technologies for combined cycle, air-breathing propulsions systems to enable reusable launch systems for access to space. Turbine Based Combined Cycle (TBCC) propulsion systems offer specific impulse (Isp) improvements over rocket-based propulsion systems in the subsonic takeoff and re turn mission segments and offer improved safety. The potential to realize more aircraft-like operations with expanded launch site capability and reduced system maintenance are additional benefits.

The National Aeronautics and Space Administration's Systems Research Aircraft (SRA), a highly modified F-18 jet fighter, on an early research flight over Rogers Dry Lake. The former Navy aircraft was flown by NASA's Dryden Flight Research Center at Edwards Air Force Base, California, to evaluate a number of experimental aerospace technologies in a multi-year, joint NASA/DOD/industry program. Among the more than 20 experiments flight-tested were several involving fiber optic sensor systems. Experiments developed by McDonnell-Douglas and Lockheed-Martin centered on installation and maintenace techniques for various types of fiber-optic hardware proposed for use in military and commercial aircraft, while a Parker-Hannifin experiment focused on alternative fiber-optic designs for postion measurement sensors as well as operational experience in handling optical sensor systems. Other experiments flown on this testbed aircraft included electronically-controlled control surface actuators, flush air data collection systems, "smart" skin antennae and laser-based systems. Incorporation of one or more of these technologies in future aircraft and spacecraft could result in signifigant savings in weight, maintenance and overall cost.

The Flight Operations crew stands before a Republic P-47G Thunderbolt at the National Advisory Committee for Aeronautics (NACA) Aircraft Engine Research Laboratory in Cleveland, Ohio. The laboratory’s Flight Research Section was responsible for conducting a variety of research flights. During World War II most of the test flights complemented the efforts in ground-based facilities to improve engine cooling systems or study advanced fuel mixtures. The Republic P–47G was loaned to the laboratory to test NACA modifications to the Wright R–2800 engine’s cooling system at higher altitudes. The laboratory has always maintained a fleet of aircraft so different research projects were often conducted concurrently. The flight research program requires an entire section of personnel to accomplish its work. This staff generally consists of a flight operations group, which includes the section chief, pilots and administrative staff; a flight maintenance group with technicians and mechanics responsible for inspecting aircraft, performing checkouts and installing and removing flight instruments; and a flight research group that integrates the researchers’ experiments into the aircraft. The staff at the time of this March 1944 photograph included 3 pilots, 16 planning and analysis engineers, 36 mechanics and technicians, 10 instrumentation specialists, 6 secretaries and 5 computers.

KENNEDY SPACE CENTER, FLA. -- Media (foreground) capture the orbiter Columbia atop a Shuttle Carrier Aircraft as it taxis down the runway. A helicopter hovers in the background. The SCA and its cargo landed at the Cape Canaveral Air Force Station Skid Strip. The ferry flight began in California March 1. Unfavorable weather conditions kept it on the ground at Dyess AFB, Texas, until it could return to Florida. Columbia is returning from a 17-month-long modification and refurbishment process as part of a routine maintenance plan. The orbiter will next fly on mission STS-107, scheduled Oct. 25

KENNEDY SPACE CENTER, FLA. -- The Space Shuttle Atlantis sits atop the Shuttle Carrier Aircraft at Kennedy Space Center’s Shuttle Landing Facility. Atlantis is being prepared for its ferry flight to California for its Orbiter Maintenance Down Period at Palmdale’s Orbiter Assembly Facility where it will remain until August 1998. At Palmdale, modifications and structural inspections will be conducted in preparation for Atlantis’ future missions to support International Space Station assembly activities. Atlantis’ next flight into space is scheduled to be Space Shuttle mission STS-92, targeted for launch from KSC in January 1999
