Apollo 15 Hammer and Feather Drop

At the end of the last Apollo 15 moon walk, Commander David Scott (pictured left)
performed a live demonstration for the television cameras. He held out a geologic
hammer and a feather and dropped them at the same time. Because they were
essentially in a vacuum, there was no air resistance and the feather fell at the same rate
as the hammer, as Galileo had concluded hundreds of years before - all objects released
together fall at the same rate regardless of mass. Mission Controller Joe Allen described
the demonstration in the "Apollo 15 Preliminary Science Report":

During the final minutes of the third extravehicular activity, a short demonstration
experiment was conducted. A heavy object (a 1.32-kg aluminum geological hammer)
and a light object (a 0.03-kg falcon feather) were released simultaneously from
approximately the same height (approximately 1.6 m) and were allowed to fall to the
surface. Within the accuracy of the simultaneous release, the objects were observed to
undergo the same acceleration and strike the lunar surface simultaneously, which was a
result predicted by well-established theory, but a result nonetheless reassuring
considering both the number of viewers that witnessed the experiment and the fact that
the homeward journey was based critically on the validity of the particular theory being
tested.

most particles in space are travelling at thousands of miles an hour relative to the moon, when they strike they are more likely to form molten masses rather than dust.

[vengencefrom1979]

the implications of producing super conducting metals in earth orbit should be self evident.

[phatmatt1176]

if you notice theres not much moon dust if the moon was billions of years old like they say there could possibly be up to 20 ft of the stuff!

[vengencefrom1979]

well debated in the 60's

"i looked through my eye scope looking for the moon rover.... no where to be found, aliens have stolen it"

Your eye scope can see a 10 foot long rover from 240,000 miles away??? Holy crap.. that's some eye scope. No one else on planet Earth has one that powerful.

Perhaps you obtained it from the aliens you mentioned?

@DcAeGaming Thanks! Nice picture if it's real!

[DcAeGaming]

@YDDES There are even pictures of the ISS right infront of the moon

google "The ISS Appears in Front of a Full Moon"

@pjwarez

I don't want to say it's aliens

ancient aliens .jpg

but its ANCIENT ALIENS.

@phatmatt1176 Actually, the rate at which cosmic dust would accumulate on an object of the moon's gravity is known, and the amount of dust on the surface is exactly what you would expect after 4.5 billion years. This is yet another silly YEC argument that has long since been refuted.

@JesusNonEnviromental You know who else believes things that are impossible for others? Crazy people. :)

[snorgatch]

@JesusNonEnviromental Funny, I think the same thing about people who believe in talking snakes and Noah's Ark. If you can believe that nonsense, you can believe anything. :)
