The U.S. space agency and Microsoft want you to help count Martian craters in the name of science
Citizen scientists and bored netizens can now help NASA map out the Martian surface for future astronaut explorers. Even kids can enjoy the thrills of Mars cartography -- namely counting craters and aligning higher-resolution images on top of a low-res map.
The U.S. space agency teamed up with Microsoft to create the online games at a newly launched website. Players can rack up reputation points for a robotic animal avatar by placing three images at a time on a Martian map, starting with the Valles Marineris canyon.
