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.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
