Answer 1

The space exploration activity that has most helped astronomers determine the age of the Moon is the collection of lunar rock samples.

The Apollo missions brought back rocks and soil from the Moon, which have been extensively studied using methods such as radiometric dating. This analysis allowed scientists to determine the age of the Moon to be about 4.5 billion years, giving insights into its formation and the history of the solar system.
