The Laser Ranging Retro reflector experiment was deployed on Apollo 11, 14, and 15. It consists of a series of corner-cube reflectors, which are a special type of mirror with the property of always reflecting an incoming light beam back in the direction it came from. A similar device was also included on the Soviet Union's Lunakhod 2 spacecraft. These reflectors can be illuminated by laser beams aimed through large telescopes on Earth. The reflected laser beam is also observed with the telescope, providing a measurement of the round-trip distance between Earth and the Moon. This is the only Apollo experiment that is still returning data from the Moon. Many of these measurements have been made by McDonald Observatory in Texas. From 1969 to 1985, they were made on a part-time basis using the McDonald Observatory 107-inch telescope. Since 1985, these observations have been made using a dedicated 30-inch telescope. Additional measurements have been made by observatories in Hawaii, California, France, Australia, and Germany.

If you can use a large telescope from earth to aim a laser to hit a reflector on the moon, how come you can't use one to photograph the landing sites in detail?
Somebody is lying! I wish they would coordinate and get their storys straight. After all these years they still can't close the gaping holes in the story line. Poor planning and coordination is the problem. Did they think we would just forget about the moon landings and go away?

if they could do it then, the ESA could do it tomorrow. And they make NASA like look people who build Deathstars.

Light has been reflected off the moon surface since 1961 or 2 , topographic maps of the Lunar surface are made by reflecting laser light off the moon surface. if there are reflectors on the Moon , which I doubt, they could have been put there by one of the unmanned missions ,human intervention would not be needed.
