California's NASA Armstrong Flight Research Center photographer Carla Thomas takes photos on January 31 of the rare opportunity to capture a supermoon, a blue moon and a lunar eclipse at the same time. A supermoon occurs when the Moon is closer to Earth in its orbit and appearing 14 percent brighter than usual. As the second full moon of the month, this moon is also commonly known as a blue moon, though it will not be blue in appearance. The super blue moon passed through Earth's shadow and took on a reddish tint, known as a blood moon. This total lunar eclipse occurs when the Sun, Earth, and a full moon form a near-perfect lineup in space. The Moon passes directly behind the Earth into its umbra (shadow).

The G-IV aircraft flies overhead in the Mojave Desert near NASA’s Armstrong Flight Research Center in Edwards, California. Baseline flights like this one occurred in June 2024, and future flights in service of science research will benefit from the installment of the Soxnav navigational system, developed in collaboration with NASA’s Jet Propulsion Laboratory in Southern California and the Bay Area Environmental Research Institute in California’s Silicon Valley. This navigational system provides precise, economical aircraft guidance for a variety of aircraft types moving at high speeds.

The Fuel Burner Rig is a test laboratory at NASA Glenn, which subjects new jet engine materials, treated with protective coatings, to the hostile, high temperature, high velocity environment found inside aircraft turbine engines. These samples face 200-mile per hour flames to simulate the temperatures of aircraft engines in flight. The rig can also simulate aircraft carrier and dusty desert operations where salt and sand can greatly reduce engine life and performance.

A Lockheed P-80 Shooting Star jet aircraft on the tarmac at the National Advisory Committee for Aeronautics (NACA) NACA Lewis Flight Propulsion Laboratory in Cleveland, Ohio. The Air Force aircraft was participating in the 1946 National Air Races over Labor Day weekend. The air races were held at the Cleveland Municipal Airport seven times between 1929 and 1939. The events included long distance, sprint, and circuit competitions, as well as aeronautical displays, demonstrations, and celebrities. The air races were suspended indefinitely in 1940 for a variety of reasons, including the start of World War II in Europe. The nature of the National Air Races changed dramatically when the event resumed in 1946. The introduction of jet aircraft, primarily the Lockheed P-80 seen here, required an entire separate division for each event. Since military pilots were the only ones with any jet aircraft experience, only they could participate in those divisions. In addition, the performance and quantity of commercially manufactured piston aircraft had increased dramatically during the war. By 1946, the custom-built racing aircraft that made the pre-war races so interesting were no longer present. The P-80 was the first US-designed and US-manufactured jet aircraft. Early models were tested during the war in NACA Lewis’ Altitude Wind Tunnel. A modified P-80 set the world’s speed record at the 1947 air races by achieving 620 miles per hour.

Researchers Robert Cummings, left, and Harold Gold with the small Low Cost Engine in the shadow of the much larger Quiet Engine at the National Aeronautics and Space Administration (NASA) Lewis Research Center. The two engines were being studied in different test cells at the Propulsion Systems Laboratory. Jet engines had proven themselves on military and large transport aircraft, but their use on small general aviation aircraft was precluded by cost. Lewis undertook a multiyear effort to develop a less expensive engine to fill this niche using existing technologies. Lewis researchers designed a four-stage, axial-flow engine constructed from sheet metal. It was only 11.5 inches in diameter and weighed 100 pounds. The final design specifications were turned over to a manufacturer in 1972. Four engines were created, and, as expected, the fabrication and assembly of the engine were comparatively inexpensive. In 1973 the Low Cost Engine had its first realistic analysis in the Propulsion Systems Laboratory altitude tank. The engine successfully operated at speeds up to Mach 1.24 and simulated altitudes of 30,000 feet. NASA released the engine to private industry in the hope that design elements would be incorporated into future projects and reduce the overall cost of small jet aircraft. Small jet and turboprop engines became relatively common in general aviation aircraft by the late 1970s.

The aircraft in this 1953 photo of the National Advisory Committee for Aeronautics (NACA) hangar at South Base of Edwards Air Force Base showed the wide range of research activities being undertaken. On the left side of the hangar are the three D-558-2 research aircraft. These were designed to test swept wings at supersonic speeds approaching Mach 2. The front D-558-2 is the third built (NACA 145/Navy 37975). It has been modified with a leading-edge chord extension. This was one of a number of wing modifications, using different configurations of slats and/or wing fences, to ease the airplane's tendency to pitch-up. NACA 145 had both a jet and a rocket engine. The middle aircraft is NACA 144 (Navy 37974), the second built. It was all-rocket powered, and Scott Crossfield made the first Mach 2 flight in this aircraft on November 20, 1953. The aircraft in the back is D-558-2 number 1. NACA 143 (Navy 37973) was also carried both a jet and a rocket engine in 1953. It had been used for the Douglas contractor flights, then was turned over to the NACA. The aircraft was not converted to all-rocket power until June 1954. It made only a single NACA flight before NACA's D-558-2 program ended in 1956. Beside the three D-558-2s is the third D-558-1. Unlike the supersonic D-558-2s, it was designed for flight research at transonic speeds, up to Mach 1. The D-558-1 was jet-powered, and took off from the ground. The D-558-1's handling was poor as it approached Mach 1. Given the designation NACA 142 (Navy 37972), it made a total of 78 research flights, with the last in June 1953. In the back of the hangar is the X-4 (Air Force 46-677). This was a Northrop-built research aircraft which tested a swept wing design without horizontal stabilizers. The aircraft proved unstable in flight at speeds above Mach 0.88. The aircraft showed combined pitching, rolling, and yawing motions, and the design was considered unsuitable. The aircraft, the second X-4 built, was then used as a pilot traine

The Boeing KC-135 Stratotanker, besides being used extensively in its primary role as an inflight aircraft refueler, has assisted in several projects at the NASA Dryden Flight Research Center, Edwards, California. In 1957 and 1958, Dryden was asked by what was then the Civil Aeronautics Administration (later absorbed into the Federal Aviation Administration (FAA) in 1958) to help establish new approach procedure guidelines on cloud-ceiling and visibility minimums for Boeing's first jet airliner, the B-707. Dryden used a KC-135 (the military variant of the 707), seen here on the runway at Edwards Air Force Base, to aid the CAA in these tests. In 1979 and 1980, Dryden was again involved with general aviation research with the KC-135. This time, a special wingtip "winglet", developed by Richard Whitcomb of Langley Research Center, was tested on the jet aircraft. Winglets are small, nearly vertical fins installed on an airplane's wing tips to help produce a forward thrust in the vortices that typically swirl off the end of the wing, thereby reducing drag. This winglet idea was tested at the Dryden Flight Research Center on a KC-135A tanker loaned to NASA by the Air Force. The research showed that the winglets could increase an aircraft's range by as much as 7 percent at cruise speeds. The first application of NASA's winglet technology in industry was in general aviation business jets, but winglets are now being incorporated into most new commercial and military transport jets, including the Gulfstream III and IV business jets, the Boeing 747-400 and MD-11 airliners, and the C-17 military transport. In the 1980's, a KC-135 was used in support of the Space Shuttle program. Since the Shuttle was to be launched from Florida, researchers wanted to test the effect of rain on the sensitive thermal tiles. Tiles were mounted on special fixtures on an F-104 aircraft and a P-3 Orion. The F-104 was flown in actual rain conditions, and also behind the KC-135 spray tanker as it rel

Matthew Sanchez uses a water jet to cut aluminum for the outer layer of the strut for the 10-foot model of the Transonic Truss-Braced Wing at NASA’s Armstrong Flight Research Center, in Edwards, California. The aircraft concept involves a wing braced on an aircraft using diagonal struts that also add lift and could result in significantly improved aerodynamics.

NASA’s X-59 quiet supersonic research aircraft sits on a ramp at Lockheed Martin Skunk Works in Palmdale, California, during sunset. The one-of-a-kind aircraft is powered by a General Electric F414 engine, a variant of the engines used on F/A-18 fighter jets. The engine is mounted above the fuselage to reduce the number of shockwaves that reach the ground. The X-59 is the centerpiece of NASA's Quesst mission, which aims to demonstrate quiet supersonic flight and enable future commercial travel over land – faster than the speed of sound.

A Highly Maneuverable Aircraft Technology (HiMAT) inlet model installed in the test section of the 8- by 6-Foot Supersonic Wind Tunnel at the National Aeronautics and Space Administration (NASA) Lewis Research Center. Engineers at the Ames Research Center, Dryden Flight Research Center, and Rockwell International designed two pilotless subscale HiMAT vehicles in the mid-1970s to study new design concepts for fighter aircraft in the transonic realm without risking the lives of test pilots. The aircraft used sophisticated technologies such as advanced aerodynamics, composite materials, digital integrated propulsion control, and digital fly-by-wire control systems. In late 1977 NASA Lewis studied the HiMAT’s General Electric J85-21 jet engine in the Propulsion Systems Laboratory. The researchers charted the inlet quality with various combinations anti-distortion screens. HiMAT employed a relatively short and curved inlet compared to actual fighter jets. In the spring of 1979, Larry Smith led an in-depth analysis of the HiMAT inlet in the 8- by 6 tunnel. The researchers installed vortex generators to battle flow separation in the diffuser. The two HiMAT aircraft performed 11 hours of flying over the course of 26 missions from mid-1979 to January 1983 at Dryden and Ames. Although the HiMAT vehicles were considered to be overly complex and expensive, the program yielded a wealth of data that would validate computer-based design tools.

A Boeing B-47 Stratojet bomber with a noise-reducing ejector on its engine at the 1957 Inspection of the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory. Representatives from the military, aeronautical industry, universities, and the press were invited to the laboratory to be briefed on the NACA’s latest research efforts and tour the state- of- the- art test facilities. Over 1700 people visited the NACA Lewis in Cleveland, Ohio during October 7 - 10, 1957. By the mid-1950s, the aircraft industry was close to introducing jet airliners to the nation’s airways. The noise produced by the large jet engines, however, would pose a considerable problem for communities near airports. This problem was demonstrated at the 1957 Inspection by an NACA Lewis researcher who played longplay (LP) audio records of military jet engines for an audience. Tests showed that the source of the loudest noise was not the engine itself, but the mixing of the engine’s exhaust with the surrounding air in the atmosphere. The pressures resulting from this turbulence produced sound waves. One of Lewis’ first studies sought to design an exhaust nozzle that reduced the turbulence. A Pratt and Whitney J57 was tested in the Altitude Wind Tunnel with many of these nozzle configurations from January to May 1957. Researchers found that the various nozzle types did reduce the noise levels but also reduced the aircraft’s thrust. Afterwards, they determined that the addition of an NACA-developed ejector reduced the noise levels without diminishing thrust.

One is a 747-100 model, while the other is designated a 747-100SR (short range). The two aircraft are identical in appearance and in their performance as Shuttle Carrier Aircraft. The 747 series of aircraft are four-engine intercontinental-range swept-wing "jumbo jets" that entered commercial service in 1969. The SCAs are used to ferry space shuttle orbiters from landing sites back to the launch complex at the Kennedy Space Center, and also to and from other locations too distant for the orbiters to be delivered by ground transportation. The orbiters are placed atop the SCAs by Mate-Demate Devices, large gantry-like structures which hoist the orbiters off the ground for post-flight servicing, and then mate them with the SCAs for ferry flights.
