Why Haven't Humans Gone Back to the Moon? (Part 2)

Why haven't humans gone back to the Moon? In Part 2, we look at the Moon's razor-sharp dust and what it does to spacesuits, why the Moon slipped down the list of priorities, and the mysteries that are pulling us back: how the Moon was born, why it's made of almost the same stuff as Earth, why it's so big for a moon, the 1/400 coincidence behind solar eclipses, the water hidden in the south pole's permanent shadows, helium-3 and titanium, and the far side that Luna 3 revealed, with a crater 2,500 km across. The pictures are real photos from NASA, ISRO, CNSA and others, except the collision, which is NASA concept art. #space #moon #farsideofthemoon Images and videos: Harrison Schmitt covered with lunar dirt, Apollo 17: NASA Eugene Cernan, Public domain — https://commons.wikimedia.org/wiki/File:Sc...
