The trajectory needed to get the Apollo 11 mission to the moon and back was calculated by a NASA mathematician.

Johnson was a black woman who worked for NASA in the 1950s and '60s.

She was the subject of a book and a movie.

Interview with author Margot Shetterly about "Hidden Figures."

Johnson's road to NASA

Johnson was the youngest of four children. She had a fascination with numbers from a very young age and would defy all expectations. I made a list. "I counted the steps to the road, the steps to the church, the number of dishes and silverware I washed, anything that could be counted, I did," said Johnson during an interview with NASA.

Her hometown didn't offer public school for black children past eighth grade, so her family moved 120 miles away so she could attend high school.

Her potential was obvious to her teachers. Johnson was encouraged to become a research mathematician by one of her professors. In 1939 she became the first black woman to attend West Virginia University's graduate math program after teaching for a few years.

She left after one year to raise her daughters. The NACA, the predecessor to NASA, hired black women to solve math problems in 1952. Johnson was the first one to apply. She was hired as a computer to perform and check calculations for flight tests.

The NACA used to rely on human beings to do the math for calculating trajectory. NASA historian Brian Odom told All About History that the human computing lab has a role forKatherine.

Johnson asked to be included in important meetings and was curious and assertive. Johnson and her black coworkers were not allowed to eat or use the restroom with the white employees. The first woman in the Flight Research Division to be credited as an author on a report was Johnson.

The degree to which we had to be assertive in those days depended on where you were. Johnson said in 1999 that she had to be when she worked for the NACA and NASA.

NACA becomes NASA

NACA became NASA in the late 1960's. Given NASA's diversity policies, Johnson's time working for the space agency would prove to be a more positive experience. There are a lot of centers in the south after NASA came online. We will think of Johnson Space Centre in Houston, Marshall Space Flight Centre in Huntsville, Alabama, and the Kennedy Space Centre in Florida, but there were other places in the south too. The build up for Apollo took place in the Jim Crow south during the time period from 1958 to 1963.

John F Kennedy in March of 1961, with a new executive order, made a key part of this programme the commitment of the federal government to equal employment opportunity. For the first time in the executive order,affirmative action is used as a term. You have to have a positive plan for affirmative action in order to bring these jobs to African Americans.

The Space Race began after the Sputnik satellite was launched by the Soviet Union.

Johnson's passion was geometry and it was used to calculate the trajectory of the spaceship. She knew that the trajectory of the Mercury mission would be a parabola. She was not deterred when NASA told her to bring the capsule down.

"You tell me when you want it and where you want it to land, and I'll do it backwards and tell you when to take off," Johnson said according to a NASA.

The trajectory for Alan Shepard's historic flight was calculated by Johnson. She confirmed that the first American would be sent into space. By this time, electronic computers were being used by NASA to do these tasks. John Glenn asked Johnson to personally check the calculations. Glenn said he was ready to go if she said they were good.

Johnson's calculations helped sync the Apollo 11 lunar landers with the moon-orbiting command and service module to get the astronauts back to Earth. She provided backup procedures that helped ensure the crew's safety when their craft malfunctioned. She co-authored 26 research reports before retiring in 1986.

Johnson's legacy

She spoke to students about her career and encouraged them to study science, technology, engineering and mathematics. She said at a NASA conference in 2010 that some things would go away. Science, engineering and technology will always exist. There will always be math. Everything is mathematics and physics.

She and her colleagues became famous with the publication of " Hidden Figures" and the release of the blockbuster movie of the same name. "Hidden Figures" made Johnson one of the most celebrated black women in space science and a hero for those calling for action against sexism and racism in science and engineering.

President Barack Obama gave the Presidential Medal of Freedom to Johnson. The NASA Langley facility renamed a building in her honor.

Johnson wrote a book for young readers in 2019.

Engineers would give me their equations and I would do more than they asked. I would try to think outside the box. She wrote that she needed to understand the thinking behind their choices to ensure that she got the answer right.

I didn't let their side- eyes intimidate or stop me. Even if I thought I was being ignored, I would keep going. I would just ask if I came across something I didn't understand.

Johnson passed away at the age of 101. Jim Bridenstine said that her legacy would be remembered.

Bridenstine said that NASA would never forget her courage and leadership. Building on her legacy is what we will do.

She was a huge part of NASA throughout her career and we look back on her fondly.

You can read more about her life and work with the New York Times. It is possible to educate your children about how great Johnson was with this book.
