This day in history, December 24

\--- 1968: Apollo 8 (American spacecraft) entered lunar orbit. The three astronauts on board, Frank Borman, Jim Lovell, and Bill Anders, were the first 3 human beings to see the moon up close and to see the dark side of the moon with their own eyes. That term “dark side” of the moon refers to the half of the moon that is facing away from the earth. In reality, that side of the moon is no darker and receives the same amount of sunlight as the half of the moon that faces the Earth. It is considered “dark” to us because that hemisphere can never be viewed from the earth. This is due to a phenomenon known as “tidal locking” which means that the moon has the same rotational period as its orbital period. In simple English, as it orbits around the earth, the moon rotates so that the same side is always facing the earth.

One hundred years ago, on the 11th December 1924, Edward Appleton conducted an experiment that proved the existence of a radio-reflecting layer high in the upper atmosphere.

This kickstarted a whole new realm of science into what was to become known as the ionosphere.

Now in 2024, Chris Scott, Professor of Space and Atmospheric Physics at the University of Reading in the UK is continuing Appleton’s important work to help us better understand the ionosphere, which is vital for efficient operation of GPS, radio communication, satellite operations.

Now you can learn more about Appleton's experiment and Chris’s wider work in this cool short video: https://www.youtube.com/watch?v=JWop2aGKKSE
