That's one precise laser shot.

The article stated "Bouncing lasers off mirrors on the lunar surface is an old trick. Astronauts walking on the moon first left reflectors behind in 1969. And since then, researchers have bounced lasers off those reflectors to make precise measurements of the distance between the moon and Earth, using the speed of light and the time it takes for the laser beam to return to Earth."
Laser measurements showing the distance between Earth and the Moon, also supports that the Earth is round. The FES wiki for the Moon shows it is only 3,000 miles above the Earthhttps://wiki.tfes.org/Moon
Using plane trigonometry and angles, you can get the shorter distance to the Moon from Earth. Telescopes recording the lunar parallax, use spherical Earth trigonometry and get the longer distance. The LLR measurements show the Earth is round![]()
