Week 4: Our Moon

Introduction

Introducing the only moon you can see with the naked eye, how does it measure up against the others, what’s under the surface and how far away is it? What did early missions to the Moon discover, and why would we want to return?

Now you’re in for a treat. You’ll be diving into the Space Race, into early manned and unmanned missions to explore our Moon.

There's now going to be a change of direction in the course. For the next three weeks, we're going to dive into the science and history of the Earth's Moon.
Aside from dictating the ocean tides, the Moon holds a special place in our culture, appearing over and over in music, art, and literature. Just think of all the music that's been inspired by a lunar theme.
Whether it's classical or pop - 'Blue moon' or 'Moonlight serenade' - everyone can think of at least one track that's inspired by the Moon.
This week, we'll cover some basic facts about our Moon. I mean, did you know it's only the fifth largest moon in the Solar System, but it's almost three-quarters the size of the planet Mercury?
We'll also cover a simple experiment calculating the distance to the Moon, which relies simply on knowing the time it takes for laser light to get there and back.
Have a great week.
