Moon astronauts physics experiment

Click For Summary

Discussion Overview

The discussion centers around the experiments conducted by astronauts during the Apollo missions to the Moon, specifically whether they performed a simultaneous drop of a penny and a feather, and the nature of other activities such as hitting a golf ball.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants inquire about the specific experiments conducted by the first astronauts on the Moon, particularly the idea of dropping a penny and a feather simultaneously.
  • One participant mentions that the activities involving hitting a golf ball and throwing a pole were not considered real experiments but rather publicity stunts, while noting that Apollo 15 featured a feather and hammer drop.
  • Another participant elaborates on the golf ball incident during Apollo 14, describing how astronaut Alan Shepard secretly modified a golf club and smuggled it onto the mission, surprising ground control.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the experiments conducted, with some considering certain activities as publicity stunts while others highlight the significance of the feather and hammer drop. The discussion remains unresolved regarding the classification of these activities as experiments.

Contextual Notes

There are limitations regarding the completeness of information about all experiments conducted during the Apollo missions, and the definitions of what constitutes a "real" experiment are not uniformly agreed upon.

Does anyone know if the first astronauts on the moon did an experiment like dropping a penny and a feather simultaneously? I just read that one pair of them hit a golf ball and threw a pole like a javelin, but that wouldn't have been my first choice of experiment.

Welcome to PF.

Those weren't real experiments, they were publicity stunts at best, but yes, on Apollo 15, an astronaut dropped a feather and a hammer:

The golf ball incident is an interesting story. It was done by Alan Shepard during Apollo 14, and no one at NASA knew what he was planning. He secretly altered a six iron club head so that it could be attached to a lunar sample scoop handle and then smuggled it and the golf ball onboard in his spacesuit. When he pulled out his "club" and ball, everyone at ground control was completely taken off guard.

Now that I didn't know. Very cool.
