Spirit and Opportunity, the spunky NASA rovers that have rolled around Mars for two years, are the unlikely stars of an IMAX movie, which opened on Friday, along with the astronomer who helped create them. Millions of people have seen photos beamed down from Mars by the robotic rovers, on television or online, but the new film, "Roving Mars," puts together these images in a seamless moving picture and splashes it on a screen five stories high.
Steven Squyres, the rovers' principal scientific investigator and the movie's main narrator, said it gives an authentic feeling of actually being on the Red Planet. "I've kind of had this picture of what Mars really looks like in my head for all this time, and for the first time on that IMAX screen, what I saw with my eyes matched my impressions of what it should really look like," Squyres said in a Reuters interview. One reason it looks so real is that all the images in the film are based on pictures taken by the rovers' own cameras or from the scientific data they have collected. "Every single scene you see is real data from the rover, it's just processed in different ways," Squyres said. "There is not a single fake shot of Mars."
A seemingly impossible shot -- the view of an airbag-covered rover landing on the planet -- was created by digital artist Dan Maas from data collected by the rovers as they bounced. Each bounce was just as it happened, just where it happened on the Martian surface. Besides the rovers and Squyres, the other stars of the film are the thousands of people who worked on the project at NASA's Jet Propulsion Laboratory and elsewhere.
