can you reflect a laser off the moon
The ongoing Lunar Laser Ranging experiment measures the distance between Earth and the Moon using laser ranging. Lasers on Earth are aimed at retroreflectors planted on the Moon during the Apollo program (11, 14, and 15), the two Lunokhod missions, and the upcoming MoonLIGHT retroreflector to be deployed by the private MX-1E lander. The time for the reflected light to return is measured, and the distance is calculated.
