SOU-SOL004-81015_full.jpgBarnacle Bill - Sol 484 visiteOriginal caption:"This frame shows portions of Sojourner's Alpha Proton X-Ray Spectrometer (APXS), a deployment spring and the rock Barnacle Bill. The image was taken by Sojourner's Rear Camera, and shows that the APXS made good contact with Barnacle Bill".

SOU-SOL004-Deimos_from_Pathfinder-PIA00996_modest.jpgDeimos, from Pathfinder - Sol 4176 visiteCaption NASA originale: "Mars' outermost natural satellite, Deimos, is seen from the Planet's surface in this Pathfinder image taken at night on Sol 4. This picture was acquired by the Imager for Mars Pathfinder (IMP) camera. Using IMP images of Deimos and its companion moon, Phobos, the spectral characteristics of the satellites and properties of the Martian atmosphere are determined".

SOU-SOL005-81095_full.jpgYogi on Mars! - Sol 5112 visiteCaption originale:"In the foreground are the airbags, and to the left are more hypothesized evaportion deposits".

SOU-SOL005-81097_full.jpgCasper - Sol 581 visiteOriginal caption:"Casper, the light colored rock in the middle left of this image, is a prime target for the APXS. The disturbed soil in the lower right of this image was caused by the retraction of the airbags".

SOU-SOL005-81101_full.jpgThe ASI-MAST - Sol 582 visiteCaption originale:"The Atmospheric Structure/Meterology Instrument MAST is standing straight up in this image. The wind socks are hanging vertically, indicating that the winds are light. ASI/MET scientists report that winds measurements have yet to exceed 10 mph. The apprent offset of the MAST in this image is caused by parallax".

SOU-SOL006-81204_full.jpgRocky Panorama (1) - Sol 667 visiteUno splendido panorama, con le solite imperfezioni (ma, per fortuna, di rilievo trascurabile questa volta) ed i soliti errori nella fase - riteniamo che sia comunque la più semplice in assoluto - di 'incollaggio' dei diversi frames che poi formeranno la fotografia completa. Molto interessanti alcuni rilievi, alti e squadrati, che sembrano caratterizzare la sommità delle colline che si vedono in lontananza (ma l'ipotesi più probabile è che si tratti di photo-artifacts).
Caption originale:"Mars Pathfinder's forward rover ramp can be seen successfully unfurled in this color image, taken on Sol 3. This ramp was not used for the deploymentof the microrover Sojourner, which occurred at the end of Sol 2. When this image was taken, Sojourner was still latched to one of the lander's petals, waiting for the command sequence that would execute its descent off of the lander's petal. The image helped Pathfinder scientists determine whether to deploy the rover using the forward or backward ramps and the nature of the first rover traverse. The metallic object at the lower part of the image is the lander's low-gain antenna. The square at the end of the ramp is one of the spacecraft's magnetic targets. Dust that accumulates on the magnetic targets will later be examined by Sojourner's Alpha Proton X-Ray Spectrometer instrument for chemical analysis. At center, a lander petal is visible".

SOU-SOL006-81225_full.jpgRocky Panorama (2) - Sol 678 visiteOriginal caption:"An area of very rocky terrain at the Ares Vallis Landing Site, along with the Lander's deflated airbags, were imaged by the IMP before its deployment on Sol 2. The high-contrast objects at lower right are portions of the Lander and its deflated airbags".

SOU-SOL006-backshell-00.jpgThe "Silver-Sphere", near Pathfinder... - Sol 6189 visiteEd ecco un frame che abbiamo fatto davvero fatica a trovare, ma del quale conoscevamo l'esistenza: la Backshell della Sonda Pathfinder.
E' evidente che le fattezze di questo oggetto, tessitura superficiale e luminosità incluse, sono IDENTICHE a quelle dell'oggetto rinvenuto dal Rover Spirit a poca distanza dal Cratere Bonneville (leggete l'articolo pubblicato su TruePlanets per maggiori informazioni e dettagli).
Mistero risolto, dunque? La Silver Sphere di Spirit è solo la sua Backshell? Apparentemente si, ma è la NASA (si, proprio la NASA!) ad ESCLUDERE questa ipotesi, collocando la Backshell di Spirit (vedi la mappa allegata all'articolo summenzionato) in un punto completamente diverso rispetto al luogo in cui le immagini che abbiamo, invece, la collocherebbero (e cioè a poche decine di metri dal rim di Bonneville Crater).
E allora? E allora, come si è detto...Il Mistero si infittisce!
Caption NASA originale:"Super-Resolution image showing the Mars Pathfinder Backshell - This image was created from 25 nearly identical frames to give one HR view of the area looking towards Big Crater. The backshell is the bright white spot at middle-left. The 2,8 mt wide and 2,1 mt high Backshell, separated from the Lander a few seconds before landing, and appears to be about 1200 mt from the Lander, to the South-South-East".
