One giant leap for mankind. Moon Landing anniversary

Fifty three years ago today, humans finally set foot on the surface of the Moon. Millions of people around the world watched Neil Armstrong step out of the Apollo Lunar Module Eagle and make his famous “giant leap for mankind”. Fellow astronaut Buzz Aldrin followed, and the pair spent more than two hours exploring the landing site and collecting samples of lunar material. Together with a third astronaut Michael Collins - who flew the command module that took them back to Earth - spent eight days in space before splashing down in the Pacific Ocean.

The Moon is Earth’s only natural satellite, orbiting our planet about every 28 days, what we refer to as a lunar cycle. This dusty ball of rock has virtually no atmosphere, no evidence of life, no water, no sound and very low gravity, yet it stabilises Earth’s wobble on its axis and moderates our climate.

Most scientists believe it was formed out of debris ejected from Earth after a massive collision with another planet-like body. If that’s true, the Moon is part of Earth, inextricably linked forever.
