(CNN) Growing up, Holly Ridings, Anne McClain and Nujoud Merancy dreamed of space.
In 2018, Ridings was announced as the first female chief flight director at NASA.
She is responsible for all of the agency's human spaceflight operations, including the International Space Station, commercial crew vehicle operations and upcoming launches.
It sounds simple, but the goals carry weight: flying humans safely and successfully in space, mission success and returning them safely back to Earth.
Ridings has thought about what she'll say to her team on the Apollo 11 anniversary; they'll be in Mission Control, launching astronauts to the space station.
During her 204 days in space, McClain worked on hundreds of experiments, including small devices that replicate human organ function and editing DNA in space for the first time.
McClain just returned to Earth after her six-month stay on the space station, but she's also one of the 12 female astronauts who could be the first woman on the moon.
