The Curiosity rover has been driving on Mars since 2012, collecting close-up images of the Mars surface. The rover team uses these images to train the rover how to recognize different types of terrain by itself, to improve the rover’s autonomous driving ability. Help classify some of the Mars images that the rover team will actually use to train the rover. Sign up at AI4Mars, complete the tutorial, and complete at least one image classification exercise. Send us a screenshot of your completed image classification. – Dave L.
