Women Engineers of the Apollo Program

In the annals of space exploration history, the Apollo Program stands as an enduring testament to human ingenuity and determination. When we think of the Apollo missions, the names Armstrong, Aldrin, and Collins immediately come to mind. However, behind the scenes, a group of remarkable women engineers played pivotal roles in the success of these historic lunar missions. In this article, we shine a spotlight on 11 of these unsung heroes and their invaluable contributions to the Apollo Program.

Breaking Barriers and Shaping Trajectories

Barbara ‘Bobbie’ Crawford Johnson

Bobbie Johnson’s journey into engineering started with a childhood fascination for airplanes. Graduating with an engineering diploma from the University of Illinois in 1946, she joined North American Aviation and later NASA. Johnson’s groundbreaking recommendation to use elliptical orbits for space flights proved instrumental in ensuring astronaut safety during propulsion failures. Her legacy is etched in the successful lunar landing.

Forging Stronger Connections in Space

Margaret W. ‘Hap’ Brennecke

Margaret ‘Hap’ Brennecke, inspired by President Kennedy’s call, became the first female welding engineer at NASA’s Marshall Space Flight Center. Her pioneering work focused on developing robust aluminum alloys capable of withstanding the harsh space environment. Despite facing discrimination, Brennecke’s innovations in welding techniques for Saturn V fuel tanks contributed significantly to the lunar missions’ success.

From Flight Enthusiast to Air Force Engineer

Arminta Harness

Arminta Harness’s love for aviation led her to become the first woman engineer in the United States Air Force. Assigned to the Gemini Program, she witnessed several launches and played a role in ensuring astronaut safety. Her personal connection to Buzz Aldrin adds a unique perspective to her remarkable journey through the Apollo era.

Designing the Future of Space Travel

Phyllis Gaylard

Phyllis Gaylard’s journey began with a degree in engineering from UCLA in 1959. Her work at TRW involved designing space vehicles and rocket engine structures, including the lunar module descent engine. Gaylard’s innovative designs, like collapsible nozzle extensions, ensured the safety of astronauts during lunar landings.

Illuminating the Moon’s Surface

Ivy Hooks

Armed with a master’s degree in mathematics and physics, Ivy Hooks joined NASA as an aerospace technologist in 1965. Her work included modeling lunar lighting and testing Apollo’s launch escape system. Hooks also contributed to the deflector protecting the Lunar Module during landing, ensuring a safe touchdown for astronauts.

Calculating Safety for Spacecraft Reentry

Dorothy ‘Dot’ Lee

Dot Lee’s transition from human-computer to engineer at NASA Langley Research Center highlights her determination to contribute to the Apollo Program. Her calculations on the Command Module’s heat shield performance were critical to astronaut safety during reentry.

Investigating Hot Spots and Lunar Samples

Georgianna Yvonne Young ‘Y.Y.’ Clark

Y.Y. Clark, a pioneer with a degree in mechanical engineering from Howard University, investigated Saturn V hot spots and their causes. She also played a key role in designing the Apollo Lunar Sample Return Container. Despite facing discrimination, she dedicated over 50 years to mentoring students and breaking barriers.

A Hidden Figure in Aerospace Engineering

Mary Winston Jackson

Mary Jackson, celebrated in the movie “Hidden Figures,” became NASA’s first black female engineer in 1958. Her work specialized in boundary layer effects on vehicles at supersonic speeds. Jackson’s contributions to analyzing aerodynamic data were vital in understanding air flow, thrust, and drag forces.

Advancing Materials Science for Spacecraft

Naomi McAfee

Naomi McAfee, with a physics degree from Western Kentucky University, rose to become Westinghouse’s first female supervisor engineer. Her work included research on environmental measurements, and the design of Apollo spacecraft hulls. McAfee’s role in ensuring the success of the Apollo 11 television camera added to her legacy.

Guiding Apollo with Mathematical Precision

Doris C. Chandler

Doris Chandler, armed with a mathematics degree from Tulane University, assumed a leadership role at NASA. Her contributions to Saturn V flight mechanics and guidance systems were invaluable. Chandler’s vision of women’s roles in space missions paved the way for future generations of female astronauts and engineers.

Navigating the Path to Astronaut Excellence

Jeanne Lee Crews

With a degree in aeronautical engineering, Jeanne Crews joined the flight crew support division at Johnson Space Center. Her work involved designing and testing flight simulators for astronauts and studying Earth landmarks for navigation. Despite the challenges and prejudices of her time, Crews played an integral role in supporting Apollo missions.
