    • HiRise Images

      Images from the HiRise library. These large area images are where the smaller images you are tasked with marking come from. Looking at them can help to put what you've seen into context. There is much to see from HiRise so to keep it relevant to this forum please restrict the images posted to South Polar ones, say latitudes of around -70 down.

    • Planet Four: Craters

      Planet Four: Craters is a citizen science project designed to help planetary scientists identify and measure features on the surface of Mars. This survey aims to determine the number of craters on the Martian surface at different scales and resolutions. By counting the craters we will be able to figure out how old various geological surfaces are! This will be a big help for the 2016 NASA InSight mission, which will use geophysical techniques such as seismology and heat flow to figure out how Mars has evolved. Knowing the age of the surface will help us to put a time-scale on that evolution.
