Scientists Calculated the Frequency With Which the Moon Experiences Impacts
When NASA sent humans to the Moon in 1969, one of the many dangers was the risk of space rocks hitting the astronauts' spacesuits or equipment.
NASA plans to send astronauts to the Moon as part of the Artemis mission by 2025. Since the space administration plans to create an inhabited base on our satellite, it is vital for scientists to understand the frequency with which the Moon experiences impacts by space objects.
When NASA sent humans to the Moon in 1969, one of the many dangers was the risk of space rocks hitting the astronauts' spacesuits or equipment. Earth protects all life from meteoroids with its dense atmosphere, whereas the Moon is vulnerable to any rocks or even dust particles flying in space.
Fortunately, the probability of a millimeter-sized object hitting a human on the Moon is 1 in 1 million per hour per person.
