SOL078-Mazatzal-A087R1.jpgMazatzal: the rock of sugar - Close-up in approximate true colors - Sol 78113 visiteCaption NASA originale:"This image was taken by the MER Spirit's PanCam during the Rover's grinding of Mazatzal with its RAT. The picture shows the untouched rock on Sol 78, which is covered in a light-toned coating and red dust particles. This approximate true-color image was created using the PanCam's red, green and blue filters".

SOL078-Mazatzal_Full-A087R1.jpgMazatzal: the rock of sugar in approximate true colors - Sol 7864 visiteCaption NASA originale:"This approximate true-color image taken by the PanCam on the MER Spirit shows the rock dubbed Mazatzal before the Rover drilled into it with its RAT. On sol 82, Spirit ground into a circular patch of the rock called 'New York', then repeated this operation on sol 85 to complete the hole. Several observations were made during this grinding process with the Rover's suite of scientific instruments. Preliminary results suggest that fluid may have been present during Mazatzal's formation. Images from the PnCam's blue, green and red filters (480, 530 and 600-nanometer filters) were combined to make this picture".
Nota: se questo è il colore "approssimativamente vero" di Mazatzal e dei suoi dintorni (ergo anche del rim di Bonneville), allora dobbiamo chiederci come mai tutte le altre immagini in colori "approssimativamente veri" - sempre a detta della NASA - dell'Area di Gusaev sono così diverse (e neppure lontanamente parenti di questa, cromaticamente parlando).

SOL079-Illinois___New_York_Rock-PIA05629.jpgMazatzal: the Illinois & New York areas - Sol 79 (Natural Colors; credits: NASA/JPL-Caltech)179 visiteUn frame in "colori veri" per lo scorcio di una parete rocciosa Marziana che, a livello di sensazione visiva, non ci sembra essere particolarmente interessante.
Possiamo comunque notare due tracce circolari che indicano l'attività delle "spazzole" di cui i Rover sono dotati e che hanno eliminato le polveri arancioni che coprono l'intero Pianeta, così riportandone alla luce i suoi "veri colori".
Ci sembra di vedere, dunque, nella traccia circolare rimasta in luce, un grigio piuttosto brillante (venato di bianco e - forse - con qualche riflesso viola...) il quale potrebbe anche ricordarci le rocce basaltiche e/o il granito.
Ma forse le nostre speculazioni sono del tutto inutili ed i "true colors" di questo frame sono "true" solo nella testa dei Tecnici NASA che lo hanno "tinteggiato"...

SOL081-Mazatzal_Postbrush-A087R1.jpgMazatzal: after the brushing - Close-up in approximate true colors - Sol 8165 visiteCaption NASA originale:"This image was taken by the MER Spirit's PanCam during the Rover's grinding of Mazatzal with its RAT. The picture shows the rock after two targets dubbed 'New York' (left) and 'Illinois' were brushed on Sol 81. The exposed, dark surface is a second coating beneath a top white veneer. This approximate true-color image was created using the PanCam's red, green and blue filters".

SOL082-09-RA-06-traverse-A082R1.jpgWhere we came from, where we are and where we'll be: Spirit's traverse Map on Sol 8262 visiteCaption NASA originale:"This map shows the MER Spirit's past and future routes across the Gusaev Crater floor. The solid red line shows where the Rover has traveled so far, from Lander to the rim of the Bonneville crater. The dotted red line indicates proposed future paths to the Columbia Hills.
Rover Team Members have not yet decided which direction Spirit will travel across Bonneville's ejecta (ejecta---->the blanket of material expelled from it during formation) and toward the Hills, as illustrated by the two diverging dotted lines.
Along the way, Spirit will stop to investigate interesting targets, including craters and plain deposits and this journey to the Hills is estimated to last about two months. The underlying image in this map was taken by the camera on NASA's MGS Orbiter".
