But we are some steps away from that actually happening.\"\u003cbr/\u003eSUPER CAPTION: Dr. Jake Matijevic, MPF Rover Manager\u003cbr/\u003eThe rover had been scheduled to record chemical information about rocks and soil on  Mars, the first step in its search for signs of ancient life on the planet.\u003cbr/\u003eBut Pathfinder, the first U-S spacecraft on Mars in 21 years, already sent to Earth  strikingly clear pictures of a rust-coloured, boulder-strewn plain. \u003cbr/\u003eScientists are most intrigued by deep, dark rocks in the colour shots and by the  incredible relief on the horizon compared to what the 1976 Viking landings found. \u003cbr/\u003eThe atmosphere also turned out to be dustier than expected, creating a salmon- coloured sky. \u003cbr/\u003eSOUNDBITE: (English) (under pictures)\u003cbr/\u003e\"We also see if you look closely that the soil is not all the same colour, that there are  areas that are more brightly coloured and others darkly coloured, definitely two different  type of soils here. That may be that some of the soil was brought in by a wind process  and dropped unto the scene and therefore isn't really native to this area or it may be for  some other reason. These are areas we hope to send the Rover over the next week or  so.\"\u003cbr/\u003eSUPER CAPTION: Peter Smith, the University of Arizona scientist who heads the  Pathfinder camera team\u003cbr/\u003eSOUNDBITE: (English)\u003cbr/\u003e\"We are really anxiously awaiting some actual atmospheric data with our solar filters  which are going to tell us precisely what the optical depth is and how it changes during  the time of day.
