July 20 is best known for 1969, when Apollo 11’s lunar module landed on the moon and Neil Armstrong became the first person to walk on its surface. The date also saw a failed bomb plot against Adolf Hitler in 1944 and NASA’s Viking 1 lander touch down on Mars in 1976.
The big story: Humans walk on the moon (1969)
At 4:18 p.m. EDT on July 20, 1969, the lunar module Eagle settled onto the southwestern edge of the Sea of Tranquility, and Neil Armstrong radioed that “the Eagle has landed.” Michael Collins circled overhead in the command module while Armstrong and Edwin “Buzz” Aldrin Jr. got ready to go outside. The hatch opened at 10:39 p.m., and at 10:56 p.m. Armstrong stepped down and delivered his line about one small step and one giant leap. He later said the word “a” got lost in transmission before “man.” Aldrin joined him at 11:11 p.m. More than a billion people followed along at home. The two planted a U.S. flag and left a plaque saying they had come in peace for all mankind. Eagle lifted off the next afternoon and rejoined Collins, and the crew splashed down in the Pacific on July 24. The space race had found its finish line.
