Help NASA Classify Martian Craters

NASA needs help classifying Martian craters. This image shows a large crater on Mars, and the task is to determine if it is fresh, degraded, or a ghost crater. Humans are currently better at complex image recognition tasks like this than computers. By volunteering, you can help astronomers understand the surface history of Mars, as there are too many craters for NASA scientists alone to classify.
