Ivy Fay Hooks (born November 17, 1941) is an American mathematician and engineer who worked for the National Aeronautics and Space Administration (NASA).

Her first assignment was with the Apollo program, where she worked on the modeling of lighting on the Moon and the dynamics of the launch escape system, among other projects.

She was named after Ivy Parker, one of the founding members of the Society of Women Engineers, and a close friend of her parents.

"[3] When she went for an interview at the Manned Spaceflight Center, she was unimpressed with the building, which was a disused box factory with no windows, and the people, who she thought were strange.

This was of great importance at the time, as it was vital to know what the view would look like when astronauts attempted to land the lunar module.

There were very few women working for NASA at the time in technical roles, and the men often played cruel practical jokes.

[6] She recalled that Max Faget walked into the room carrying a balsa wood model airplane and declared; "We’re going to build America’s next spacecraft.

[5][7] For her work on the design of the Space Shuttle, Hooks received the Arthur S. Flemming Award in 1978,[5] and the NASA Exceptional Service Medal in 1981.
