Black Woman Saved NASA With Just Pencil and Paper When Computers Failed

Hinzugefügt: 2026-05-26

[00:00:00]Did you know that when America's most advanced [music] computers failed, a black woman's mind saved the space program? 1962.

[00:00:08]John Glenn is about to become the first American to orbit Earth, but NASA's [music] computers keep spitting out different numbers for his flight path.

[00:00:15]One wrong calculation [music] means Glenn burns up in space or gets lost forever. The astronaut refuses [music] to launch. He demands that the girl, Katherine Johnson, check every number [music] by hand. While her white colleagues used mechanical calculators, Katherine's brain [music] was the computer. She'd been doing calculus since high school, solving equations that stumped college professors. For 3 days, [music] she calculated orbital mechanics with just pencil and paper, launch windows, trajectory angles, splashdown coordinates. Every number had to be perfect. Her mathematics matched the computers exactly. Glenn finally agreed [music] to launch. Katherine didn't stop there. She calculated the path to the moon for Apollo 11. Her equations are still used today. 35 years at NASA, 26 research papers. She sent men to the [music] stars. Yet, for decades, America forgot her name. The woman who saved space [music] exploration remained hidden until she was 90 years old. Black brilliance, always there, often invisible, forever essential.
