I got to put this one in your bag before I can get it

...they'd laid on the lunar surface for millions of years...

Coming off this rock here, but it looks like caliche

It was hoped they'd uncover secrets about the Moon...

...they ended up teaching scientists a lot about the Earth too

Nine containers of lunar samples were brought back to Earth

...learnt a great deal about the many impacts...

Ancient volcanic eruptions then filled some of these basins...

...that can be seen by humans on Earth...

...was the one that created the Moon itself

Scientists found the Moon rocks to be surprisingly...

...perhaps disappointingly, like those on Earth

It turns out that the Earth and the Moon...

...are chemically very similar indeed, as if twins

It was this revelation that led to a game-changing idea...

...the impact fills nearby space with a doughnut of hot vapour

...which binds the Moon and Earth to each other...

...of the rise and fall of the Earth's ocean tides

Scientists believe these tides could have been crucial...

...for the evolution of animal life on Earth...

...by offering a route from under the sea to above it

Now missions are being planned to its unexplored territories

Just as the United States was the first nation to reach the Moon...

...so too will we be the first nation to return astronauts...

The hope of the next generation of scientists...

...is that by studying new samples of rock...

...they can unlock many more of the Moon's secrets...
