Moon Lasers

Thursday, March 3, 2016 | |

Take a flashlight (torch) for example.

It only reflects about 7% of the visible light that hits it.

So, even the best lasers combined with the best telescopes aren't going to be effective at reflecting visible light off of the surface.

But
those
mirrors
are
highly
reflective.
That's 1.7 in 100,000,000,000,000,000 photons.

Your eye isn't going to have such luck.

 Here's a picture of APOLLO shining its laser on the moon.
