Humans Really Walked on the Moon: The Evidence They Left

Some people still say the Moon landings were faked. The astronauts left equipment that scientists still use, and an orbiter has photographed it.

On 20 July 1969, Apollo 11's lunar module landed on the Moon. Neil Armstrong and Buzz Aldrin spent about 22 hours there, while Michael Collins waited in orbit in the command module.

Before leaving, they set up a panel of mirrors called a laser ranging retroreflector. It is still in use: observatories on Earth fire laser pulses at it and time their return, measuring the distance to the Moon to within a millimetre.

Those measurements show the Moon drifting away from Earth by about 1.5 inches a year. It is the one Apollo 11 experiment that has kept running ever since.

NASA's Lunar Reconnaissance Orbiter, circling the Moon since 2009, has photographed the landing site: the descent stage the astronauts left behind and the trails their footprints made.

Evidence

  • Laser pulses aimed at the Apollo 11 site come back from the reflector the crew left there.
  • Orbital photographs show the lunar module's descent stage and the astronauts' footpaths.

Verdict

CONFIRMED

Backed by strong, verifiable evidence.

Confirmed. Independent laser measurements and orbital photographs show the hardware the astronauts left on the surface.

Theories vs evidence

  • The landings were staged in a studio

    RULED OUT

    The reflectors left on the Moon still return laser pulses, and an orbiter has photographed the landers and tracks.
