How have scientist collected information about the moon?

Scientists have collected information about the Moon through various methods, including lunar missions, telescopic observations, and robotic landers. Notable missions, such as NASA's Apollo program, sent astronauts to the Moon, collecting samples and conducting experiments. Additionally, unmanned spacecraft like the Lunar Reconnaissance Orbiter have mapped the lunar surface and gathered data on its composition and geology. Remote sensing techniques and analysis of lunar meteorites have also contributed to our understanding of the Moon's history and environment.
