50 years ago today, on August 2, 1971, Apollo 15 Commander Dave Scott took advantage of the absence of an atmosphere on the Moon to demonstrate a finding by Galileo hundreds of years earlier, that all objects released at the same time will fall toward a center of gravity at the same rate regardless of mass. In this experiment, Scott drops a hammer and a feather, which then both hit the lunar surface simultaneously. | Project Apollo Archive

T 417 (10.17.24): Experiment (2) – Galileo's Fall Experiment Until Galileo, a 16th-century astronomer, people believed that the speed at which an object fell depended on its mass—specifically, that heavier objects always fell faster than lighter ones. However, in the 1600s, Galileo proposed that if air resistance were negligible, objects of different masses would fall at the same rate. In this experiment, I have two objects inside the depressed vacuum chamber: a piece of mylar (the stuff from he

In 1971, astronaut David Scott conducted Galileo's famous hammer/feather drop experiment on the moon, during the Apollo 15 mission. Galileo had concluded that all objects, regardless of mass, fall at the same speed -- however, the resistance caused by the air (as in the case of the feather in Earth's atmosphere) can cause the feather to drop slower. Well, on the moon there is no atmosphere (a vacuum), so the objects should drop at the same speed. Follow us: @astro.voyagers 🛸 . •. 🌎 ° .• 🌓 • .
