This Thursday was a historic day for humanity when it landed successfully on the dark side of the moon. But what is this area really?
To understand what the Moon's "other side" means, it is important to note that the moon is in synchronous rotation around the Earth. That means it uses the same time to translate around our planet than to rotate on its own axis so we can't see its hidden face or "dark side".
Previously, other spacecraft could observe this hidden face, but no one landed on it. It all started with the Soviet spacecraft Luna 3, which made the first photographs of the moon's hidden face in October 1959. It took 29 images 66,700 km away, showing mountainous terrain and two dark areas.
Although over time, people have sent probes to many places in the room and have photographs of the hidden side of the moon, they did not land on it. Why? It wasn't as easy as it seemed. Historically, it was said that it would cause communication problems. Similarly, the countries' interest fell over time.
But China has achieved it in a historic mission. Just as the Soviet Union took the first photographs nearly six decades ago, China has managed to get down to a crater on this side of the moon. A moon landing that will surely provide valuable information to researchers (see this note).
