On Saturday, we remember an important day from 55 years ago. On July 20, 1969, two American astronauts, Neil Armstrong and Buzz Aldrin, walked on the moon for the first time. This weekend, the night sky will have a full moon to celebrate this special memory.
Buzz Aldrin, who is now 94 years old and the only one of the first moonwalkers still alive, will go to a big party at the San Diego Air and Space Museum. Lots of people will remember the famous words Neil Armstrong said when he first stepped on the moon: "That's one small step for man, one giant leap for mankind."
There are many ways to learn about this moon landing. Some museums are having special events. People can also watch a new movie called “Fly Me to the Moon.” If you can't go to these events, you can also see information about Apollo 11 on a special website by the Smithsonian National Air and Space/ Museum.
Neil Armstrong and Buzz Aldrin spent a little over two hours on the moon before they went back to their space module and joined their friend Michael Collins, who was waiting in space. People were very excited when the spaceship came back to Earth and landed in the water.
The spacesuits the astronauts wore and the capsule they used are now in a museum. There are also pieces of the moon, called moon rocks, that the astronauts brought back. These rocks are kept in a special place where scientists study them.
NASA, which is America's space agency, plans to send more astronauts around the moon soon. This won't be until after 2025. They want to learn more about the moon and maybe even have people live there one day. We learn about space to help us understand more about our world and maybe find new places where people can go.
