SOU-SOL003-81007_full.jpgTwin Peaks - Sol 491 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?!?Ago 20, 2005

SOU-SOL003-80903_full.jpgHorizon - Sol 390 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".Ago 20, 2005

SOU-SOL003-80904_full.jpgPanorama with Twin Peaks - Sol 396 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".Ago 20, 2005

SOU-SOL003-80894_full.jpgHuge rocks around Pathfinder - Sol 2139 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".Ago 17, 2005

SOU-SOL003-80893_full.jpgAres Vallis' Horizon and Pathfinder - Sol 2130 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".Ago 17, 2005

SOU-SOL002-80827_full.jpgBig Rock - Sol 1128 visiteOriginal caption:"This image of the Martian surface was taken by the Imager for Mars Pathfinder (IMP) before sunset on July 4 (Sol 1), the spacecraft's first day on Mars. The airbags have been partially retracted, and portions of the petal holding the undeployed rover Sojourner can be seen at lower left. The rock in the center of the image may be a future target for chemical analysis.
The soil in the foreground has been disturbed by the movement of the airbags as they retracted".
Nota: questa immagine, come le due che seguono, è relativa al Sol 1 ma è stata ricevuta sulla Terra durante il Sol 2.Ago 17, 2005

SOU-SOL002-80828_full.jpgDetails and Features of the Pathfinder - Sol 1111 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".Ago 17, 2005

SOU-SOL002-80839_1full.jpgMars Panorama: photomosaic - Sol 1138 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 - è 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".Ago 17, 2005

SOU-SOL001-i1246750998img0008140027.jpgRocks around the Pathfinder - Sol 1165 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 qualità del frame, come vedete, è pessima e, anche operando un ingrandimento davvero modesto, il risultato (l'unico) che si ottiene è 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 effettività della Missione, poichè 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.Ago 17, 2005

SOU-SOL001-80813_full.jpgColor Panorama: Sol 1133 visiteView of martian surface taken by the Imager for Mars Pathfinder (IMP), the camera on board the Mars Pathfinder lander. This image was taken in mid-morning on Mars (2:30 PM Pacific Daylight Time, July 4, 1997). Part of the small rover, Sojourner, is visible on the left side of the picture. The tan cylinder to the right of the rover is one of two rolled-up ramps by which the rover will descend to the ground. The white, billowy material in the center of the picture is part of the airbag system. Many rocks of different shapes and sizes are visible between the lander and the horizon. Two hills are visible on the horizon. The notch on the left side of the leftmost conical hill is an artifact of the processing of this picture. Ago 13, 2005

SOU-SOL001-80816_full.jpgColor Panorama: Sol 1166 visiteLanding on surface of Mars in Ares Vallis. Transmitter turned off shortly after landing to save power. After touchdown, the following sequence occurs: 1) Lander bounces and rolls to a stop 2) Airbags deflate and are retracted up against the petals 3) Petals open.
These events of the entry, descent and landing phase are complete between 11:32 a.m. and 12:33 p.m. PDT. A semaphore signaling the end of this phase is received via the Lander's Low-Gain Antenna.
At 2 p.m. PDT Sunrise at the Landing Site occurs. Operations begin for Sol 1 (note: Sol is a Mars day, --> such as 24 h and about 40').
The transmitter is turned on and the Spacecraft signals Earth through the Low-Gain Antenna. This communications session will contain telemetry from all engineering subsystems including the Rover and the first science data about the atmosphere taken during descent. Carrier is received at 1:55 p.m. PDT; following ground processing, actual first information are received by flight controllers at approx. 2:09 p.m. PDT.
Original caption:"In this image from the Pathfinder IMP camera, a wide diversity of rocks are strewn in the foreground. A (small) hill is visible in the distance (note: the notch within the hill is an image artifact). Airbags are seen at the lower right".Ago 13, 2005
