SOU-SOL004-81003_full.jpgEarly steps, early rolls, early pictures... - Sol 4117 visiteOriginal caption:"This is one of the first images taken by one of the three forward-facing rover cameras. It shows the partially deflated airbags and, in the upper right corner, the HGA - High Gain Antenna".

SOU-SOL003-80894_full.jpgHuge rocks around Pathfinder - Sol 2151 visiteOriginal caption:"This image was taken on July 5 by the IMP camera. The flat, table-like rock appears to be covered with dust and it also displays many interesting linear features.
The large rocks in the background are intriguing because of their impressive textures".

SOU-SOL001-i1246750998img0008140027.jpgRocks around the Pathfinder - Sol 1186 visiteQuesta immagine in b/n che "chiude" la Panoramica Ufficiale dei frames Pathfinder a colori ricevuti sulla Terra durante il Sol 1 (4 Luglio 1997) rappresenta un campione davvero esemplare per quella categoria di immagini che noi chiamiamo "indecifrabili".
La qualit del frame, come vedete, pessima e, anche operando un ingrandimento davvero modesto, il risultato (l'unico) che si ottiene quello di rendere l'immagine totalmente inguardabile. Difficile stimare, anche qualora ci volessimo accontentare di un'ampia approssimazione, la distanza e le dimensioni degli oggetti ripresi.
Un'immagine che non fornisce risposte, anzi...Stimola migliaia di domande e fa sorgere enormi dubbi (ma - non fraintendeteci - NON sulla effettivit della Missione, poich sappiamo che questo frame proviene da Marte). Dubbi che, nel tempo, da piccole crepe nelle pareti della coerenza e della fiducia nella trasparenza dei dati raccolti durante le Missioni Spaziali, diventano voragini (sovente) irreparabili.

SOU-SOL003-81010_full.jpgCouch Rock - Sol 3111 visiteOriginal caption:"This new view of the rock dubbed "Couch" was taken by the deployed Imager for Mars Pathfinder (IMP) on Sol 3.
Earlier images, taken by the undeployed IMP, hinted that Couch was balanced upon the rectangular rock approximately three-quarters of the way up from the bottom of the image. The deployed IMP, standing 1,8 meters above the Martian surface, has now revealed Couch to be a free-standing object positioned at the Martian horizon".

SOU-SOL003-81007_full.jpgTwin Peaks - Sol 4100 visiteOriginal caption:"The two hills in the distance, approximately 1,6 Km away, have been dubbed the "Twin Peaks" and are of great interest to Pathfinder scientists as objects of future study. The white areas on the left hill, called the 'Ski Run' by scientists, may have been formed by hydrologic processes".
Nota: non sembra anche a Voi che il "Peak" alla Dx del frame assomigli, in maniera davvero impressionante, ad un'altra collinetta Marziana - molto famosa - e conosciuta come Husband Hill?!?

SOU-SOL003-80903_full.jpgHorizon - Sol 398 visiteOriginal caption:"This image shows the diversity of rocks at the Ares Vallis site. The large rocks seem to lean in a uniform direction (so-called "imbrication"). This observation suggests that catastrophic floods once ran through the site. Seen on the horizon is a faint peak".

SOU-SOL003-80904_full.jpgPanorama with Twin Peaks - Sol 3104 visiteOriginal caption:"Named Twin Peaks, the formation of two hills in the background are of extreme geological interest. The left hill has a smooth apron which may have been caused by gravitational processes or water. The hill on the right seems to have horizontal bands running through it. As of yet unidentified, the bands may be deposits, sedimentary layers, or terraces cut by erosion.
The Twin Peaks in the distance are approximately 1,6 Km from the Sagan Memorial Station. The rocks in the foreground are very diverse. Some are rounded and suggest transport by water, others are tabular and angular and indicate non-aqueous deposition. Preliminary hypotheses are that the angular rocks were thrown from ancient, nearby impact crater sites".

SOU-SOL003-80893_full.jpgAres Vallis' Horizon and Pathfinder - Sol 2151 visiteOriginal caption:"Taken on July 5, this image shows portions of the high gain antenna, a petal and the retracted airbags. Geologists are eager to examine the rocks of the Ares Vallis terrain. As predicted, the landing site has provided a grab bag of diverse rock types and sizes".

SOU-SOL002-80828_full.jpgDetails and Features of the Pathfinder - Sol 1133 visiteOriginal caption:"Several prominent features of Mars Pathfinder and surrounding terrain are seen in this image, taken by the Imager for Mars Pathfinder on July 4 (Sol 1), the spacecraft's first day on the Red Planet. Portions of a lander petal are at the lower part of the image. At the left, the mechanism for the high-gain antenna can be seen. The dark area along the right side of the image represents a portion of the low-gain antenna. The radiation calibration target is at the right. The calibration target is made up of a number of materials with well-characterized colors. The known colors of the calibration targets allow scientists to determine the true colors of the rocks and soils of Mars. Three bull's-eye rings provide a wide range of brightness for the camera, similar to a photographer's grayscale chart. In the middle of the bull's-eye is a 5-inch tall post that casts a shadow, which is distorted in this image due to its location with respect to the lander camera. A large rock is located at the near center of the image. Smaller rocks and areas of soil are strewn across the Martian terrain up to the horizon line".

SOU-SOL002-80839_1full.jpgMars Panorama: photomosaic - Sol 1158 visiteGiunzioni fatte male, parte del frame predisposto per la visione anaglifica (3D) - alla Vostra Sx - ed incredibili errori nel montaggio dei diversi pezzi dell'immagine complessiva: fretta o totale incompetenza? Sia nell'uno che nell'altro caso, la NASA - in situazioni come questa - inescusabile!
Caption originale:"The Sojourner rover and undeployed ramps onboard the Mars Pathfinder spacecraft can be seen in this image, by the Imager for Mars Pathfinder (IMP) on July 4 (Sol 1). This image has been corrected for the curvature created by parallax. The microrover Sojourner is latched to the petal, and has not yet been deployed. The ramps are a pair of deployable metal reels which will provide a track for the rover as it slowly rolls off the lander, over the spacecraft's deflated airbags, and onto the surface of Mars. Pathfinder scientists will use this image to determine whether it is safe to deploy the ramps. One or both of the ramps will be unfurled, and then scientists will decide whether the rover will use either the forward or backward ramp for its descent".

SOU-SOL039-5-SunrisePthf-PIA01548_modest.jpgSunrise on Mars from Pathfinder - Sol 39 (True Colors; credits: NASA/JPL)177 visiteCaption NASA:"Sunrise, Sol 39. This true color, pre-sunrise image (approximately 05:30 MLT) is composed of six images extending 30 in azimuth and 45 in elevation and shows the brownish gray predawn sky. A description of the techniques used to generate this color image from IMP data can be found in Maki et al., 1999. Note: a calibrated output device is required accurately reproduce the correct colors.
Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C. JPL is an operating division of the California Institute of Technology (Caltech). The IMP was developed by the University of Arizona Lunar and Planetary Laboratory under contract to JPL. Peter Smith is the Principal investigator".
