Exploring the Unknown
People have always wanted to go into space - now we can!
What is there to explore?
We have only been to a very small part of space. If we could travel a lot faster, we would be able to see other stars and other planets. Unfortunately, these are all too far away for us to travel to at the moment, but in future we might be able to visit them.

Who explores space?
All space missions are either manned (with people) or unmanned (with robots). Unmanned missions are cheaper and easier so are used for distant missions. Manned missions have people involved so are more difficult to prepare but can be easier to carry out.

Where have we explored?
So far humans have only been as far as the Moon. We first landed there in 1969. The mission was called Apollo 11 and was part of NASA's Apollo program. The astronauts who walked on the Moon were Neil Armstrong and Buzz Aldrin. This was the first time anybody had stood on ground which wasn't on Earth.
