Welcome to "Today in Space," where we peer back in our archives to find historic moments in spaceflight and astronomy. So enjoy a blast from the past with Space.com's Hanneke Weitering to look back at what happened on this day in space!
On July 20, 1969, human beings walked on the moon for the very first time!
Apollo 11 astronauts Neil Armstrong and Buzz Aldrin exited their lunar lander and planted their moon boots on the lunar surface at about 11 p.m. Eastern Time. Armstrong led the way down the ladder. The world watched via live television as Armstrong took his first step and said those historic words: "That's one small step for a man … one giant leap for mankind."
Once Armstrong and Aldrin found their footing, they got straight to work. They inspected the spacecraft to look for any damage from the landing, set up cameras, collected moon rocks and planted the American flag into the soil. They also strolled around the moon to assess the mobility of their spacesuits.
And that's what happened today in space!
