Just ask space scientist Laurie Leshin, president of Worcester Polytechnic Institute.The giant Saturn V rocket was 111 meters (363 feet) tall, about the height of a 36-story-tall building. Here is a view of Earth from Apollo 11, shortly after it left Earth orbit.Happy Apollo 11 mission officials in the Launch Control Center following the successful Apollo 11 liftoff on July 16, 1969.Her specialty: writing code to help astronauts return to Earth.The day Apollo 11 lifted off, Jo Ann Morgan was the lone woman in the launch firing room at Kennedy Space Center in Florida. Also in Florida were Zeldin and her family, who were invited to watch the launch at Cape Canaveral. Zeldin said she and her colleagues were sure Americans could land on the moon.“We need that diversity, and we need people to see themselves in space exploration because we’re going to need all of them to succeed in the future.”“Our astronauts didn’t have much time, but thankfully, they had Margaret Hamilton,” President Obama said in 2016 when he presented the Cambridge resident with the Presidential Medal of Freedom, the nation’s highest civilian honor.The world watched on television as Neil Armstrong took the first steps on the moon’s surface on July 20, 1969.

Try this video: Why the Apollo moon landings could not have been faked.Three minutes before Apollo 11’s lunar module was supposed to set down on the moon, an alarm did go off — Hamilton’s software was able to determine it wasn’t a major glitch and the landing procedure continued.“Our astronauts didn’t have much time, but thankfully, they had Margaret Hamilton,” President Obama said in 2016 when he presented the Cambridge resident with the Presidential Medal of Freedom, the nation’s highest civilian honor. Things are still being done out of ignorance today, such as paying women lower salaries than men and relegating women most often to the lower positions in an organization.”Nathalia Holt, author of “Rise of the Rocket Girls,” which chronicles the stories of women space pioneers, estimates that women comprised about 25 percent of the early space program, either working for NASA directly or indirectly through centers and labs.Margaret Hamilton (left) with a stack of Apollo Guidance Computer source code developed by her and her team and Frances “Poppy” Northcutt in the ITN studios with a model of the Apollo 14 lunar module. Before the widespread use of computers, humans did the computing, and for a time manual math computations were considered women’s work.
