Did Katherine Johnson Use Euler's Method?

As told in the book (and movie) Hidden Figures, Katherine Johnson led the team of African-American women who did the actual calculation of the necessary trajectory from the earth to the moon for the US Apollo space program. They used Euler's method to do this.

What method of math did Katherine Johnson use?

Katherine studied how to use geometry for space travel. She figured out the paths for the spacecraft to orbit (go around) Earth and to land on the Moon. NASA used Katherine's math, and it worked! NASA sent astronauts into orbit around Earth.

What did Katherine Johnson calculate?

In 1961 she calculated the path for Freedom 7, the spacecraft that put the first U.S astronaut in space, Alan B. Shepard, Jr. The following year, at the request of John Glenn, Johnson verified that the electronic computer had planned his flight correctly.
