Vacuum Chamber

A giant NASA vacuum test chamber originally built to test the spacecraft that astronauts used to fly to the moon. The Chamber is located in the Space Environment Simulation Laboratory at NASA's Johnson Space Center in Houston. It is the largest high-vacuum, cryogenic-optical test chamber in the world. Designed in 1965 to fit the Apollo command and service modules mated together, Chamber A stands 120 feet tall (36.6 meters) and has an exterior diameter of 65 feet (19.8 m). Inside is a volume of 400,000 cubic feet (11,327 cubic meters), which means when its 40-foot (12.2 m), 40 ton door — the largest single-hinged door in the world — is open, there are 50,000 pounds (22,680 kilograms) of air inside. [Space.com]

NASA has had this facility since 1965. It is large enough to take a Moon Landing Module and could easily be setup as a moon scape.  With a black background and some home made regolith, astronauts would have no trouble moving about kicking dust up and even driving the Moon Rover.

The hammer and feather test would work just as well here as it would on the Moon's surface. Even Professor Brian Cox, for one of his television documentaries, carried out the same experiement within this very complex.

There is no doubt that objects of unequal mass will fall at the same speed and contact the ground at the same time. That is not in question here. What is in question is that this experiement did not have to be conducted on the Moon's surface. It didn't even have to be conducted in a vacuum chamber on Earth, because a one kilogram ball will fall at the same speed as a 100 gram ball. There is no need to use a feather to demonstrate the theory it can be demonstrated here on Earth in our planets atmosphere using different sized spheres. So why did NASA need to show an experiement on the moon? Because they used it to give credentials to their claims.
