Forty-seven years ago today, two men walked on the Moon for the very first time.
The scientific importance of the Apollo 11 mission’s importance is often over-played – the other 10 astronauts in the Apollo Program that walked on the Moon had much longer missions on the surface than 11’s two and a half hours, and so achieved more scientifically.
But it was Apollo 11 that brought back the first photographs, the first impressions, and the first physical rock samples from another world.
Their lunar samples confirmed that the Moon had a common origin to Earth – cue the ‘giant impact’ theory – while seismometers laid by Armstrong and Aldrin measured Moon-quakes that proved that the Moon had a core, a mantle and a crust, just like Earth.
The historic places and treasured memorabilia from the Apollo 11 mission is mostly preserved and easy to find, but only if you know where to look.
