The CMU Hyperion robot has completed project Sun Sync, an initial test on Devon Island in which it autonomously navigated during a six mile journey over frozen arctic terrain similar to that of Mars. Hyperion's testing is part of the Haughton-Mars Project, a larger NASA project that simulates Mars mission elements. Ananova and Cosmiverse are covering the Hyperion story (and don't forget to check out the webcams watching the rest of the Mars mission simulation.)
