Crater counting dating
We can determine the relative age of one surface to another (is it older or younger?) by looking at which has more craters: The surface with more craters will be older because, when you assume that craters will form randomly across the body, then the surface with more craters has had more time to accumulate them.One useful source is the Consolidated Lunar Atlas (Kuiper et al, 2006).Make a histogram that shows the distribution of diameters.If you want a Project Idea with full instructions, please pick one without an asterisk.Get good photographs of the Moon showing lots of craters and count how many craters you find in a range of diameter classes.Most of these craters were formed during the first billion years of the Moon's formation, but you should confirm that this is true for the the Moon areas you've selected in your photographs by doing background research.
If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help.Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. They want to understand the entire universe—the nature of the Sun, Moon, planets, stars, galaxies, and everything in between.An astronomer's work can be pure science—gathering and analyzing data from instruments and creating theories about the nature of cosmic objects—or the work can be applied to practical problems in space flight and navigation, or satellite communications.I presented this in a talk at the recent Lunar and Planetary Science Conference at AM, when most people were learning about the latest results from Ceres.The project started simply enough: I downloaded some of the amazing images taken by NASA's Lunar Reconnaissance Orbiter's Wide-Angle Camera (WAC) that showed the Apollo and Luna landing sites.
