Langley Research Center

• 1. Introduction

  ›

  Langley Research Center sits in Hampton, Virginia, near the Chesapeake Bay front of Langley Air Force Base, and it holds a distinction that no other NASA facility can claim: it is the oldest of the agency's field centers. But its story begins before NASA even existed. In February 1917, a publication called Aviation Week warned that American military aviation lagged badly behind what was already flying in the skies over Europe. That warning set off a chain of events that would shape aviation and space exploration for more than a century. Who built this place, and why? What did its researchers actually do that nobody else had done before? And why, when the time came to pick a home for Mission Control, did the people at Langley lose out to a city in Texas they never expected to beat them?

• 2. A Warning and a Command

  ›

  President Woodrow Wilson read the intelligence and acted. He sent Jerome Hunsaker to Europe to assess the state of military aviation firsthand, and Hunsaker's report was stark enough to prompt Wilson to order the creation of the nation's first aeronautics laboratory. That laboratory would become what we now call NASA Langley. The National Advisory Committee for Aeronautics, known as NACA, established the Langley Memorial Aeronautical Laboratory on Langley Field in 1917, less than three years after the NACA itself had been created. Both the field and the laboratory took their names from Samuel Pierpont Langley, the aviation pioneer. The Aviation Section of the U.S. Signal Corps had already set up a base there that same year, and the two institutions began growing side by side as World War I demonstrated just how valuable air power could be. By 1920, the first research facilities were in place and aeronautical research was underway. At that point, the entire scientific staff consisted of just four researchers and eleven technicians.

• 3. Wind Tunnels and World Records

  ›

  In 1934, engineers at Langley Field completed what was then the largest wind tunnel on the planet. Its test section measured 30 by 60 feet, large enough to place a full-scale aircraft inside and study how air actually moved around it. That facility held the record as the world's largest wind tunnel until the 1940s, when a 40 by 80 foot tunnel was completed at NASA's Ames Research Center in California. But Langley did not stop there. Researchers at the center built the world's first transonic wind tunnel, a facility that could test aircraft approaching the speed of sound. The 1940s-era 16-foot transonic wind tunnel eventually supported research for every major American fighter jet developed after 1960, including the F-14, F-15, F-16, F-18, and the Joint Strike Fighter, before going inactive in 2004. Work to remove it began in July 2011. By that point, Langley had shifted its transonic testing to the National Transonic Facility, a high-pressure, cryogenically cooled 8.2-foot closed-loop tunnel that could push experiments to conditions no earlier facility could match. LaRC also supported the design and testing of the hypersonic X-43, which set a world speed record of Mach 9.6.

• 4. The West Area Computers

  ›

  From 1943 through 1958, a group of African American women worked as human computers at Langley Research Center. They were mathematicians who performed the calculations that guided aeronautical research before electronic computing took over. They were called the West Area Computers, and the name came directly from the geography of the campus: these women worked in Langley's West Area, while the white mathematicians worked in the East section. Their placement was not a coincidence. Virginia's Jim Crow laws applied to the Langley campus, and the segregation of facilities was legally enforced. These women spent fifteen years performing work that was essential to the center's output under conditions that reflected the broader racial injustice of the era. Their contributions to aeronautics research ran parallel to the center's most productive peacetime decades, a period when subsonic flight was advancing and the first serious studies of supersonic and hypersonic travel were beginning.

• 5. The Race to Space

  ›

  When NASA replaced NACA in 1958, Langley became the main office of the Space Task Group, the organization that ran Project Mercury. That designation lasted from 1958 through 1963, covering the years when American human spaceflight was first being attempted. Langley researchers trained the earliest crews of astronauts and designed the procedures for rendezvous in orbit. In 1965, the center opened the Lunar Landing Research Facility, a gantry structure that suspended a mock Apollo Lunar Module above a simulated lunar landscape to let crews practice landing in reduced gravity. Langley also tested physical hardware for space, including the Apollo Lunar Module itself. The center's reach extended beyond the Moon: Langley supported the Viking program, which carried spacecraft to Mars. In mid-February 1961, Langley orbited its first payload, NASA's Explorer 9 balloon satellite, marking the moment when a facility built to study aircraft began sending objects beyond the atmosphere.

• 6. The Houston Decision

  ›

  At some point in the early 1960s, NASA needed to choose a permanent home for its Manned Spacecraft Center, the facility that would manage human spaceflight going forward. Langley was a serious candidate. The center was already NASA's most prominent installation. The Hampton Roads region surrounding it had a substantial aerospace industry. Washington, D.C. was close by. By every visible measure, Langley looked like the obvious choice. The selection of Houston came as a genuine shock to many senior people at the center. The decision caused lingering controversy in the surrounding area for years, largely because it meant the transfer of a large number of jobs from Virginia to Texas. Langley did retain a meaningful role in the Apollo Program, contributing research and astronaut training even after losing the mission control function. But the loss stung in ways that took time to settle. The center that had built American aviation from four researchers and eleven technicians into a world-class institution found itself watching another city claim the most visible prize in the space age.

• 7. Legacies on the Ground

  ›

  Not every breakthrough from Langley involved a rocket or a wind tunnel. Researchers there developed the standards for grooving aircraft runways, building on a British design that had first been used at Ronald Reagan Washington National Airport. The principle behind the technique is straightforward: cutting parallel grooves into runway pavement reduces aquaplaning, which gives aircraft tires better grip during heavy rain. What Langley did was formalize the specifications so the approach could be applied consistently. That standard is now the international baseline for runways around the world. LaRC scientists and engineers have won the Collier Trophy, one of aviation's most prestigious honors, five times. In February 2025, Dr. Trina Marsh Dyal, who had previously served as Deputy Director, was appointed Acting Center Director, becoming the latest in a line of leaders stretching back to Leigh M. Griffith, who took charge on the 1st of November 1922.
