Lunar crater survey set to improve understanding of cosmic impacts

Nature : Since June 2009, NASA’s Lunar Reconnaissance Orbiter has been surveying the Moon’s surface with a resolution of 50 cm. As Nature‘s Roberta Kwok reports, researchers are using the survey data to measure lunar craters. From those measurements a clearer idea should emerge of the timing and nature of the bombardments that created the craters and changed the surfaces of other solar system bodies, including Earth.
