how do you compare us with people from the moon. Explain?
The Apollo program (not the lunar missions with astronauts) being conducted at the Apache Point Observatory uses a 3.5 - m telescope to direct lasers at retro-reflectors left on the Moon by the Apollo astronauts. the Moon is 384, 472 km away approximately how long do the operators need to wait to see the laser light return to Earth? (Hint: The speed of light is 300,000 km/s.]
