Sunday marked the 45th anniversary of the day that Neil Armstrong became the first man on the moon.

The NASA astronaut made history on July 20, 1969, just four days after departing from the Kennedy Space Center on Merrit Island in Florida, according to the International Business Times. Armstrong, the Apollo 11 commander, embarked on the extraterrestrial journey with Michael Collins and Edwin Aldrin, who served as the command module pilot and the lunar module pilot, respectively.

At 10:56 p.m. ET, television viewers all around the world watched a live broadcast of Armstrong as he took his first steps on the moon, and said the famous words, “That’s one small step for man, one giant leap for mankind.”

In celebration of the lunar milestone, and in remembrance of Neil Armstrong, who passed away in 2012, that same broadcast was aired Sunday in Time Square. And, NASA announced in a statement that “starting at 10:39 p.m., when Armstrong opened the spacecraft hatch to begin the first spacewalk on the moon,” NASA TV would air the famous footage for viewers.
