I decided to do research about the Apollo missions and came across an article that talked about the discovery of water on the moon. In 2009, India's Chandrayaan-1 probe and two NASA spacecraft found water clinging to much of the lunar surface, which surprised many scientists.

Did any of the other 380 kilograms of samples from the Apollo missions have clues of water that were overlooked? Where did the water come from? The significance of this discovery was that new theories about how there came to be water on the moon were conceived (comets, Mars-sized planet that collided with the Earth to make the moon). The discoverers relied on the work of others
