SOU-SOL015.jpgClouds... - Sol 1564 visiteThese clouds from Sol 15 have a new look: as water ice clouds cover the sky, the sky takes on a more bluish cast. This is because small particles (perhaps 1/10th the size of the Martian dust, or 1/1000th the thickness of a human hair) are bright in blue light, but almost invisible in red light. Thus, scientists expect that the ice particles in the clouds are very small. The clouds were imaged by the Imager for Mars Pathfinder (IMP).%19 %584 %2006

SOU-SOL042-Flat_Top_left.jpgFlat-Top close-up (1) - Sol 4289 visiteThese two images make a stereo pair taken from the Soujourner Rover's Front Cameras on the morning of Sol 42. Visible in the foreground is the rock nicknamed Flat Top. Based on previous images from the Pathfinder Lander camera, Flat Top appeared to have a layered texture (in the opinion of some scientists). These close-up images show that this is probably not the case. The texture visible on the side of the rock is made up of elongated pits, which may be either vesicles from volcanic outgassing or etches caused by weathering. The boundary between the edge and top of the rock exhibits topography, some of which correlates to the flute-like texture on the top surface. These depressions may have been carved by the wind, but more study of Flat Top is needed before this can be confirmed.%19 %581 %2006

SOU-SOL039-1.jpgSagan Memorial Station - Sol 3978 visiteCaption NASA originale:"This is one of the best images of the Sagan Memorial Station taken by the Soujourner Rover. Looking out from the Rock Garden, the Camera Mast and High Gain Antenna can clearly be seen above the American flag and the Jet Propulsion Laboratory logo".%19 %544 %2006

SOU-SOL035.jpgWind-tails - Sol 3566 visiteThis image was taken by the Soujourner Rover's Left Front Camera on Sol 32. The Pathfinder Lander is at right and is about 9 mt away. Wind tails of dust are clearly seen extending from the left side of many of the small rocks in the foreground. The large rocks on the horizon at left center are the next goal of Soujourner as it continues our exploration of Mars.%19 %467 %2006

SOU-SOL020.jpgRock Garden - Sol 20 and 3858 visiteThis preliminary enhanced color image mosaic of the area North-East of the lander was made using images acquired in the afternoon of Sol 20 (top portion of the mosaic) and Sol 38 (bottom portion of the mosaic) by the IMP camera as part of the Super-Pan data set. The differences in brightness between the upper and lower portions of the mosaic result from slightly different sun angle positions between Soles 20 and 38, and can be compensated by subsequent analysis of the reflectance of surface rocks and soils under different lighting conditions.
Red, green, and blue filter images from the right eye were combined to simulate slightly amplified natural color. The bright, flat areas Scooby Doo and Baker's Bench are visible left of center and above center in the mosaic, respectively. Airbags and a portion of one of the lander petals are visible in the foreground.%19 %459 %2006

SOU-SOL013-1.jpgBoulder Field - Sol 1358 visiteThis enhanced color image mosaic of the area south of the lander was made using images acquired in the mid-morning of Sol 13 by the IMP camera as part of the Super-Pan data set.
At each camera frame position, a Super-Pan image contains 15 frames (6 frames for 3-color stereo and 9 more individual narrow color bands). This mammoth color and stereo data set will be used to derive high quality topographic maps of the surface and detailed shapes of rocks and other surface features, and to map subtle chemical, mineralogical, and textural variations on rocks and soils. Red, green, and blue filter images from the right eye were combined to simulate slightly amplified natural color. The rocks Squid, Ender, Hassock, and a portion of Wedge are visible in the center-right portion of the mosaic. Mermaid Dune and Bosco rock are visible in the middle-left. The foreground contains portions of the airbags and the top of the low-gain antenna on the lander.
The rim of the impact crater "Big Crater" is visible in the upper-left on the horizon.%19 %456 %2006

SOU-SOL032.jpgRock Garden - Sol 32 (Enhanced Natural Colors; credits: NASA/JPL)70 visiteThis enhanced color image mosaic of the Rock Garden area west of the lander was made using images acquired in the mid-morning of Sol 32 by the IMP camera as part of the Super-Pan data set.
At each camera frame position, a Super-Pan image contains 15 frames (6 frames for 3-color stereo and 9 more individual narrow color bands). This mammoth color and stereo data set will be used to derive high quality topographic maps of the surface and detailed shapes of rocks and other surface features, and to map subtle chemical, mineralogical, and textural variations on rocks and soils. Red, green, and blue filter images from the right eye were combined to simulate slightly amplified natural color. The "bookshelf" rocks visible in the background include Shark, Half-Dome, Moe and Stimpy. The Rover Soujourner completed imaging and APXS measurements of these rocks on Sol 71. Small rocks below and to the right of Flat Top appear to have been moved and/or pushed into the soil, probably by the spacecraft during landing. A portion of South Peak is visible in the upper right corner of the mosaic. One of the solar-panel-covered lander petals and the forward rover ramp are visible in the foreground.%19 %453 %2006
