To see if their is water on the moon
Scientists study the moon using a combination of telescopes, spacecraft, and lunar missions. They analyze data collected from these missions to learn about the moon's composition, structure, and history. Scientists also use remote sensing techniques to gather information about the moon's surface features and geological processes.
They were able to see it through a powerful telescope.
Because they have had astronauts there, and they can see it through telescopes very well.
Scientists publish the details of important experiments so that people can recreate it and see the results for themselves.
