> While NASA's Mars Exploration Rover Opportunity was traveling from
> Victoria crater to Endeavour crater, between September 2008 and August
> 2011, the rover team took an end-of-drive image on each Martian day that
> included a drive. A new video compiles these 309 images, providing an
> historic record of the three-year trek that totaled about 13 miles (21
> kilometers) across a Martian plain pocked with smaller craters.
> The video featuring the end-of-drive images is now available online, at
> It shows the rim of Endeavour becoming visible on the horizon partway
> through the journey and growing larger as Opportunity neared that goal.
> The drive included detours, as Opportunity went around large expanses of
> treacherous terrain along the way.
> The rover team also produced a sound track for the video, using each
> drive day's data from Opportunity's accelerometers. The low-frequency
> data has been sped up 1,000 times to yield audible frequencies.
> "The sound represents the vibrations of the rover while moving on the
> surface of Mars," said Paolo Bellutta, a rover planner at NASA's Jet
> Propulsion Laboratory, Pasadena, Calif., who has plotted many of
> Opportunity's drives and coordinated production of the video. "When the
> sound is louder, the rover was moving on bedrock. When the sound is
> softer, the rover was moving on sand."
> Opportunity and its rover twin, Spirit, completed their three-month
> prime missions on Mars in April 2004. Both rovers continued for years of
> bonus, extended missions. Both have made important discoveries about wet
> environments on ancient Mars that may have been favorable for supporting
> microbial life. Spirit stopped communicating in 2010. Opportunity
> continues its work at Endeavour. NASA will launch the next-generation
> Mars rover, car-size Curiosity, this autumn, for arrival at Mars' Gale
> crater in August 2012.
