Apollo 15 Commander Dave Scott demonstrated Galileo’s theory on the Moon by dropping a hammer and a feather, showing that objects fall at the same rate regardless of their mass.

The moon has a thin atmosphere that would have slowed down the feather.
The moon has no atmosphere. It's not Mars. The moon has, at most, an extremely thin exosphere, which is almost a vacuum and has only about one hundred trillionth of the air pressure on Earth. But you can read about this in thousands of books and all over the internet. I don't know where your ignorance comes from.
exo ia not athmosphere. I have no idea how anyone could come up with the idea that a few molecules per cubic centimeter could visibly slow down the spring. Unbelievable.
