Neil Armstrong was the first person to walk on the moon. He said, "That's one small step for a man, one giant leap for mankind." Now, many countries are working together to explore space. The International Space Station (ISS) is a good example. Astronauts from different countries live and work on the ISS. They do experiments and learn more about space.
