Space Exploration Day 2025 – July 20, 2025

We celebrate Space Exploration Day every year on July 20. Also known as National Moon Day, President Ronald Reagan created this holiday to commemorate the first crewed mission to the moon and moon landing, which took place on July 20, 1969. Eight years after President John F. Kennedy set a goal for America to land on the moon before the end of the decade, the Apollo 11 mission succeeded. The day also seeks to inspire and encourage young people to pursue careers in space sciences and space exploration. So, let’s look to the heavens and remember the incredible space advances humanity has made thus far, and dream of where we will still go.

History of Space Exploration Day

On July 16, 1969, NASA’s Apollo 11 mission launched from the Kennedy Space Center in Florida, U.S.A. There were three astronauts aboard the rocket ship — Neil Armstrong, Edwin ‘Buzz’ Aldrin, and Michael Collins. At 1:46 p.m. on July 20, the lunar module nicknamed the ‘Eagle,’ carrying only Aldrin and Armstrong, separated from the command module where Collins was.At exactly 10:56 p.m. on that day, Armstrong became the first human to set foot on the moon as he descended from the ladder, making the famous quote that is now known all over the world: “That’s one small step for man, one giant leap for mankind.” In reality, Armstrong claimed that he actually said, “That’s one small step for a man, one giant leap for mankind.” His words were garbled by the microphone he was using. Nineteen minutes later, Aldrin also planted his boots on the moon’s surface.For the next several hours, both men planted the U.S. flag, took photographs of the surroundings, and even communicated with President Richard Nixon. That night, Aldrin and Armstrong slept in the lunar module on the moon’s surface. By 1:45 p.m. on July 21, the Eagle began its ascension back to the other module, successfully rejoining it about four hours later. Finally, on July 22 at 12:56 a.m., the journey back to Earth commenced, and Apollo 11 made a safe splash into the Pacific Ocean on July 24, at 12:50 p.m.
