In the 1960’s NASA explored the moon. In 1969, they put a man on the moon. Later NASA built SkyLab, a research station in space. They also made the Space Shuttle. This vehicle that could go into space many times instead of just once. Since 1993 NASA has been working with other countries on the International Space Station (ISS).

These are some of NASA’s big projects. They have also done research in many other areas. They have learned a lot about space. They have also helped invent things that ordinary people use everyday. Some examples are water filters, glasses that are hard to scratch, and roads with grooves on the sides.
