10 People You Wish You Met from 100 Years of NASA’s Langley

Something happened 100 years ago that changed forever the way we fly. And then the way we explore space. And then how we study our home planet. That something was the establishment of what is now NASA Langley Research Center in Hampton, Virginia. Founded just three months after America’s entry into World War I, Langley Memorial Aeronautical Laboratory was established as the nation’s first civilian facility focused on aeronautical research. The goal was, simply, to “solve the fundamental problems of flight.”

From the beginning, Langley engineers devised technologies for safer, higher, farther and faster air travel. Top-tier talent was hired. State-of-the-art wind tunnels and supporting infrastructure was built. Unique solutions were found.

Langley researchers developed the wing shapes still used today in airplane design. Better propellers, engine cowlings, all-metal airplanes, new kinds of rotorcraft and helicopters, faster-than-sound flight - these were among Langley’s many groundbreaking aeronautical advances spanning its first decades.

By 1958, Langley’s governing organization, the National Advisory Committee for Aeronautics, or NACA, would become NASA, and Langley’s accomplishments would soar from air into space.

Here are 10 people you wish you met from the storied history of Langley:

Robert R. “Bob” Gilruth (1913–2000) 

  • Considered the father of the U.S. manned space program.
  • He helped organize the Manned Spacecraft Center – now the Johnson Space Center – in Houston, Texas. 
  • Gilruth managed 25 crewed spaceflights, including Alan Shepard’s first Mercury flight in May 1961, the first lunar landing by Apollo 11 in July 1969, the dramatic rescue of Apollo 13 in 1970, and the Apollo 15 mission in July 1971.

Christopher C. “Chris” Kraft, Jr. (1924-) 

  • Created the concept and developed the organization, operational procedures and culture of NASA’s Mission Control.
  • Played a vital role in the success of the final Apollo missions, the first manned space station (Skylab), the first international space docking (Apollo-Soyuz Test Project), and the first space shuttle flights.

Maxime “Max” A. Faget (1921–2004) 

  • Devised many of the design concepts incorporated into all U.S.  manned spacecraft.
  • The author of papers and books that laid the engineering foundations for methods, procedures and approaches to spaceflight. 
  • An expert in safe atmospheric reentry, he developed the capsule design and operational plan for Project Mercury, and made major contributions to the Apollo Program’s basic command module configuration.

Caldwell Johnson (1919–2013) 

  • Worked for decades with Max Faget helping to design the earliest experimental spacecraft, addressing issues such as bodily restraint and mobility, personal hygiene, weight limits, and food and water supply. 
  • A key member of NASA’s spacecraft design team, Johnson established the basic layout and physical contours of America’s space capsules.

William H. “Hewitt” Phillips (1918–2009) 

  • Provided solutions to critical issues and problems associated with control of aircraft and spacecraft. 
  • Under his leadership, NASA Langley developed piloted astronaut simulators, ensuring the success of the Gemini and Apollo missions. Phillips personally conceived and successfully advocated for the 240-foot-high Langley Lunar Landing Facility used for moon-landing training, and later contributed to space shuttle development, Orion spacecraft splashdown capabilities and commercial crew programs.

Katherine Johnson (1918-) 

  • Was one of NASA Langley’s most notable “human computers,” calculating the trajectory analysis for Alan Shepard’s May 1961 mission, Freedom 7, America’s first human spaceflight. 
  • She verified the orbital equations controlling the capsule trajectory of John Glenn’s Friendship 7 mission from blastoff to splashdown, calculations that would help to sync Project Apollo’s lunar lander with the moon-orbiting command and service module. 
  • Johnson also worked on the space shuttle and the Earth Resources Satellite, and authored or coauthored 26 research reports.

Dorothy Vaughan (1910–2008) 

  • Was both a respected mathematician and NASA’s first African-American manager, head of NASA Langley’s segregated West Area Computing Unit from 1949 until 1958. 
  • Once segregated facilities were abolished, she joined a racially and gender-integrated group on the frontier of electronic computing. 
  • Vaughan became an expert FORTRAN programmer, and contributed to the Scout Launch Vehicle Program.

William E. Stoney Jr. (1925-) 

  • Oversaw the development of early rockets, and was manager of a NASA Langley-based project that created the Scout solid-propellant rocket. 
  • One of the most successful boosters in NASA history, Scout and its payloads led to critical advancements in atmospheric and space science. 
  • Stoney became chief of advanced space vehicle concepts at NASA headquarters in Washington, headed the advanced spacecraft technology division at the Manned Spacecraft Center in Houston, and was engineering director of the Apollo Program Office.

Israel Taback (1920–2008) 

  • Was chief engineer for NASA’s Lunar Orbiter program. Five Lunar Orbiters circled the moon, three taking photographs of potential Apollo landing sites and two mapping 99 percent of the lunar surface. 
  • Taback later became deputy project manager for the Mars Viking project. Seven years to the day of the first moon landing, on July 20, 1976, Viking 1 became NASA’s first Martian lander, touching down without incident in western Chryse Planitia in the planet’s northern equatorial region.

John C Houbolt (1919–2014) 

  • Forcefully advocated for the lunar-orbit-rendezvous concept that proved the vital link in the nation’s successful Apollo moon landing. 
  • In 1963, after the lunar-orbit-rendezvous technique was adopted, Houbolt left NASA for the private sector as an aeronautics, astronautics and advanced-technology consultant. 
  • He returned to Langley in 1976 to become its chief aeronautical scientist. During a decades-long career, Houbolt was the author of more than 120 technical publications.

Apollo 9 Performs First Rendezvous & Re-Docking with LM Ascent Stage (7 March 1969) — The Lunar Module (LM) “Spider” ascent stage is photographed from the Command and Service Modules (CSM) on the fifth day of the Apollo 9 Earth-orbital mission. While astronaut David R. Scott, command module pilot, remained at the controls in the CSM “Gumdrop,” astronauts James A. McDivitt, Apollo 9 commander; and Russell L. Schweickart, lunar module pilot, checked out the “Spider.” The LM’s descent stage had already been jettisoned.


Lunar Orbit Rendezvous

Lunar orbit rendezvous (LOR) is a key concept for landing humans on the Moon and returning them to Earth and was first utilized for the Project Apollo missions in the 1960s and 1970s. In a LOR mission, a main spacecraft (such as the Apollo CSM) and a smaller lunar lander (such as the Apollo LM) travel together into lunar orbit. The lunar lander then independently descends to the surface of the Moon, while the main spacecraft remains in lunar orbit. After completion of the mission there, the lander returns to lunar orbit to rendezvous and re-dock with the main spacecraft, then is discarded after transfer of crew and payload. Only the main spacecraft returns to Earth.

LOR is first known to have been proposed in 1916 by Ukrainian rocket theoretician Yuri Kondratyuk, as the most economical way of landing humans on the Moon. When NASA began actual work in 1961 on President John F. Kennedy’s goal to achieve the first such landing by the end of the 1960s, LOR was proposed by Tom Dolan and championed by John C. Houbolt, but considered controversial, impractical, and possibly dangerous, because space rendezvous had never been done. However, Houbolt’s persistence paid off, convincing NASA’s management, and Administrator James E. Webb publicly announced in July 1962 that Apollo would utilize this method. Even then, Kennedy’s Science Advisor Jerome Wiesner remained opposed to the method, and publicly criticized Webb. As history has shown, the method worked, and allowed NASA to use only one Saturn V per lunar landing mission, something other landing options did not offer.
