HAMPTON, VA–When she heard that NASA’s Langley Research Center in Hampton, Virginia, would name its newest building after her, Katherine Johnson responded the only way she could – with surprise.
“You want my honest answer? I think they’re crazy,” the 99-year-old Johnson, of “Hidden Figures” fame, said with a laugh.
The Katherine G. Johnson Computational Research Facility, or CRF, was dedicated Sept. 22 with a ribbon-cutting ceremony attended by family and friends of Johnson and her fellow “human computers,” students from Black Girls Code and the 21st Century Community Learning Centers program, and special guests from across Virginia.
“You have been a trailblazer,” Virginia Gov. Terry McAuliffe said during the ceremony. “When I think of Virginia and the history of what we’ve gone through … you’re at the top of that list.”
Johnson held a fascination with numbers as a girl growing up in West Virginia. Eventually, she translated that love into using her math skills to help advance the nation’s space program in the 1960s.
“I like the stars, and the stories we were telling, and it was a joy to contribute to the literature that was going to come out,” said Johnson, the central character in the book and movie “Hidden Figures.” “But little did I think it would go this far.”
“We’re here to honor the legacy of one of the most admired and inspirational people ever associated with NASA,” said Langley Director David Bowles. “I can’t imagine a better tribute to Mrs. Johnson’s character and accomplishments than this building that will bear her name.”
State of the art
The CRF is a state-of-the-art facility that will enable innovative research and development supporting NASA’s missions. It is the third building in Langley’s 20-year revitalization plan.
“I always like something new,” Johnson said of the facility. “It gives credit to everybody who helped.”
The $23-million, 37,000-square-foot (3,437 square-meter) structure is consolidating four Langley data centers. The building incorporates energy-saving features that are expected to be 33 percent more efficient than if those features had not been included.
The significance of the facility is that it advances Langley’s capabilities in modeling and simulation, big data and analysis. Powerful computers like those in the CRF are capable of ever more complex analysis and simulation, in some cases replacing but also validating and complimenting the research done in NASA’s labs and wind tunnels. The CRF also houses an office area for researchers to do their work.
“We know that these are the tools that will help shape the world of the future,” Bowles said. “We’ll do more calculations that ever, and we’ll do them faster, more efficiently and with greater reliability.”
Johnson was a “human computer” at Langley who calculated trajectories for America’s first spaceflights. She worked at Langley from 1953 until retiring in 1986. Her contributions and those of other NASA African-American human computers are chronicled in “Hidden Figures,” based on author Margot Lee Shetterly’s book of the same name. After Johnson’s story began to emerge, she was awarded the Presidential Medal of Freedom, the nation’s highest civilian honor, by then-President Barack Obama at the White House in 2015.
In 1962, as NASA prepared for the orbital mission of John Glenn, Johnson was called on to do the work that she would become most known for. The complexity of the orbital flight had required the construction of a worldwide communications network, linking tracking stations around the world to computers in Washington, Cape Canaveral, Florida, and Bermuda.
The computers had been programmed with orbital equations that would control the trajectory of the capsule in Glenn’s Friendship 7 mission, from blast off to splashdown, but the astronauts were wary of putting their lives in the care of the electronic calculating machines, which were prone to hiccups and blackouts.
As a part of the preflight checklist, Glenn asked engineers to “get the girl” — Johnson — to run the same numbers through the same equations that had been programmed into the computer, but by hand, on her desktop mechanical calculating machine.
“If she says they’re good,” Johnson remembers Glenn saying, “then I’m ready to go.” Glenn’s flight was a success, and marked a turning point in the competition between the U.S. and the Soviet Union in space.
Breaking down barriers
“Thank goodness for the book and movie to come out so people got to understand what this woman meant to our country,” Gov. McAuliffe said. “She really broke down the barriers.”
Shetterly, the ceremony’s keynote speaker, praised Johnson and fellow human computers Mary Jackson and Dorothy Vaughan as being revolutionary by just doing their jobs. “We are living in a present that they willed into existence with their pencils, their slide rules, their mechanical calculating machines – and, of course, their brilliant minds.”
Shetterly said the path to the future is rarely predictable, smooth or direct – and Johnson’s was no exception.
“At every fork, her talent, her hard work and her character pulled her toward her destiny,” she said. “At every turn, she made a choice to become the protagonist in her own story and then of ours.”
Shetterly said Johnson’s story is one of a thirst for knowledge and a celebration of teamwork.
“Telling your story has been an honor,” she said. “You work changed our history and your history has changed our future.”
Johnson, who received four standing ovations at the ceremony, happily recalls her time at Langley, saying that her job was to just answer questions to the best of her ability at all times, whether she got them correct or not.
“I didn’t do anything alone but to try to get to the root of the question – and succeeded there,” she said.
