Measuring and dating Lunar Craters with Salsa J

There are two types of regions on the Moon: craters and seas. Craters are created when a large meteorite hits the Moon. Seas are formed during geological events that flatten large areas of the Moon. Some regions have been explored by other astronauts who have brought back samples. Thanks to their analysis, we have been able to determine when these regions were formed. However, it is not possible to take samples from everywhere on the Moon.
