This video describes a simulated 32 day Mars mission conducted with scientists at Lavic Lake in May 1997. From emulated descent imagery obtained by helicopter, planetary geologist Ray Arvidson selected four locations to be visit: desert pavement, dry lakebed, cratered playa, and an alluvia fan. Rocky 7 drove greater than 1km and visited all sites, where imagery and science instrument readings were obtained. Details may be found in: R. Volpe, Navigation Results from Desert Field Tests of the Rocky 7 Mars Rover Prototype, International Journal of Robotics Research, Special Issue on Field and Service Robots, 18(7), July 1999. (7min)
