Katherine Johnson: Indispensable Brightness NASA Couldn’t Dim

​As we dive into historical icons who made a powerful impact on society but rarely received proper recognition, one can’t help but think of powerful black women, especially those who were indispensable, like Katherine Johnson.

Katherine Johnson is a woman whose brilliance was necessary at an institution like NASA, even during a male-dominated and segregated time, where her space contributions were undeniably vital yet minimized.

What would have astronauts done without the knowledge and accuracy of an influential trailblazer like Katherine? We will probably never know, but there's no doubt that there would be plenty of space mission delays and trouble making space exploration possible without her.

While we navigate Katherine’s experience during her role at NASA, we’ll learn how vital her presence was by detailing moments that proved she was an authoritative figure who made a difference.

John Glenn Pauses an Orbital Mission Until Katherine Ensures Security

​Imagine having the brains to determine whether it’s safe to launch an orbital flight--that’s precisely what Katherine had. She was a mathematician who knew how to calculate numbers that could accurately determine life or death. She was the one NASA sought before launching John Glenn’s orbital mission in 1962, the same year computers were introduced, but still weren’t reliable.

These factors were a concern for NASA, including Glenn himself, which is where his refusal to fly stemmed from until he had “the girl,” as he called Katherine, to calculate by hand the orbital numbers they had already programmed into unreliable machinery. His confidence in Katherine was undeniable, and the person who gave him the go-ahead to complete a spaceflight that would earn him the title of the first American to do so.

“Get the girl. If she says they’re good, then I’m ready to go.”

Computers Weren’t Enough, But NASA had Katherine

NASA couldn’t entirely depend on early computers because they were experimental machines that astronauts couldn’t trust. John Glenn would be the first American to complete an orbital flight, but the machinery's unreliability sparked fear and hesitation. Knowing that a single miscalculation could potentially result in death or disappearance wasn’t something Glenn was willing to endure. Fortunately, there was Katherine, the genius who brought accuracy and ease with her ability to verify whether the orbital flight would go right or wrong, and to detect other details that early machines couldn’t.

A Strong Black Woman in a Segregated System

There was absolutely no doubt that Katherine was a powerhouse at NASA, and her expertise were valued and essential despite working in a segregated unit. But her brilliance was often marginalized, with a job title like “human computer” which was used to hide her true identity. She was also left out of essential meetings, but refused to be excluded by showing up regardless of the racial and gender discrimination that was taking place.

Successful Mission but No Praise or Merit

​John Glenn’s mission was a success, and he completed three orbital flights and returned safely to Earth. Still, the hard labor Katherine put in and the efforts that made this mission possible went unrecognized. Public praise was given to astronauts and technology while keeping her contribution out of sight.

Closing Thoughts

Katherine’s exceptional brilliance and innate abilities proved that you can make a positive impact, even in unjust and unfortunate circumstances. It also shows that even though she endured the misfortune of not receiving the credit she deserved, progress depended on the aid of her unseen labor. Fortunately, there will always be comfort in knowing that, before NASA could rely on any machinery, they trusted a powerful black woman named Katherine Johnson.
