๐ Hammer and feather fall together on the Moon
In 1971, Apollo 15 astronaut David Scott dropped a hammer and a feather on the Moon to test physics. He performed this demonstration during the final minutes of the third lunar surface excursion on the Moon. The hammer weighed 1.32 kilograms and the feather 0.03 kilograms, released from about 1.6 metres. This showed that without air resistance, objects fall at the same rate regardless of their mass. The experiment provided a direct, theatrical illustration of Galileo's principle in a vacuum. ๐
