The Moon is about 384,000 kilometres away from Earth. That is roughly ten times around the world. Apollo 11 took three days to get there, travelling at over 40,000 kilometres per hour. When the lander finally touched the Moon's surface, the radio crackled and Armstrong said: 'The Eagle has landed.'
Neil Armstrong was the first to step out. As his boot touched the dust, he said: 'That's one small step for man, one giant leap for mankind.' Buzz Aldrin climbed down 19 minutes later. The two of them spent about two and a half hours bouncing about on the Moon, planting a flag, collecting rocks and taking photos.
The Moon has no air, no wind and no rain. So when astronauts press their boots into the dust, the footprints stay exactly where they are. Armstrong and Aldrin's footprints from 1969 are almost certainly still there today - dust patterns from over 50 years ago, perfectly preserved.
Since 1969, twelve people in total have walked on the Moon - all of them between 1969 and 1972. Nobody has been back since. But new missions are being planned right now, with astronauts from many countries hoping to go in the next few years. The next person to walk on the Moon might be alive in a school today.
