The Astro Drone game is part of a scientific crowdsourcing project. People who possess a Parrot AR drone can play the game, in which they are challenged to perform different space missions in an augmented reality. Contribute to future space exploration by playing the free Astro Drone game! The app is more than a game. Players can choose to contribute to a scientific crowdsourcing experiment that aims to improve autonomous capabilities of space probes, such as landing, obstacle avoidance, and docking. The app processes the images made by the AR drone's camera, extracting abstract mathematical image features. These features can neither be interpreted by humans, nor can the original image be reconstructed. However, the features can be used by robots to learn how to navigate in their environment. Players can join the experiment by going to the high score table. If they agree, the feature data is sent over the Internet. The latest release contains two levels. In the first players learn to dock as well as possible to the International Space Station. In the second level players enact the Rosetta mission from ESA, by avoiding space debris and releasing the Philae lander onto a comet's surface. New levels will be added incrementally with new releases. Astro Drone is a project performed by the Advanced Concepts Team of the European Space Agency.
