Wall Street Journal: The Moon has a lot more water than previously believed, according to analyses of NASA data published today in five research papers in the journal Science. Last year NASA crashed a rocket into a lunar crater and then used a pair of orbiting satellites to analyze the debris created by the impact. The discovery could be important for such future projects as establishing a manned lunar base from which to launch other interplanetary missions. Water’s components, hydrogen and oxygen, are key ingredients for rocket fuel, and the oxygen can be used to make breathable air.
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.
