SOL759-2N193748574EFFAODQP0695R0M1~0.jpgHome Plate (1) - Sol 75987 visiteIn a race to collect as much scientific data as possible before the onset of Martian Winter, Spirit climbed to the top of "Home Plate" and acquired images of the surrounding terrain. Each day, Spirit logs a reduction in the total amount of solar energy collected as the Sun sinks lower on the Planet's Northern Horizon.
The Science Team's objective is to do as much science as possible while concentrating on a drive campaign that will move the Rover to the north-facing slopes of McCool Hill. The team has already begun mapping routes to McCool, where Spirit will attempt to survive a second Martian winter with its solar panels tilted toward the Sun.

SOL761-2P193924940ESFAODQP2587L2M1~1.jpgSame subject, different views (1) - Sol 76168 visiteNe avevamo parlato in passato, ne abbiamo riparlato di recente, ma qualche Amico Lettore continua a chiederci che cosa intendiamo dire allorchè parliamo di "trasformazione del paesaggio a seguito del cambio di filtro/colore".
Un quesito legittimo: la materia non è semplice. E allora, per essere più chiari, eccoVi una coppia di frames che vale più di cento pagine di chiacchiere: lo stesso - piccolo - rilievo ripreso due volte dalla stessa camera - la Camera Panoramica o PanCam - usando due diversi filtri/colore (il 2 ed il 7) con meno di un minuto di tempo trascorso fra uno scatto e l'altro e con uno delta prospettico nullo (l'occhio della PanCam che ha effettuato le riprese è sempre il Sx ed il Rover non si è mosso fra le due riprese).
Il risultato? Due rilievi radicalmente diversi.
Giudicate Voi adesso...
Caption originale:"Left PanCam Non-linearized Sub-frame EDR acquired on Sol 761 of Spirit's mission to Gusev Crater at approximately 12:45:42 MLT.
Camera commanded to use Filter 2 (753 nm)".

SOL759-2F193748136EFFAODOP1206R0M1.jpgFront-View (2) - Sol 75958 visiteSol 755 (Feb. 16, 2006): before moving on, Spirit rolled back from Manager and collected data from the site with the MTES (Miniature Thermal Emission Spectrometer). The Rover paused to take mid-drive images with the NavCam before "sliding into" Home Plate after driving 10 mt (about 33 feet) using visual odometery and 1,5 mt (about 4,9 feet) using autonomous navigation.
Odometry: as of Sol 755, Spirit's total odometry was 6.575 mt (such as 4,09 miles).

SOL759-2F193746982EFFAODGP1201R0M1.jpgFront-View (1) - Sol 75958 visiteSol 753: Spirit acquired images of a rock target dubbed Gray using the MI, brushed a surface target known as Manager using the RAT (Rock Abrasion Tool), and completed an 18-hour analysis of Manager using the Mössbauer Spectrometer. The Science Team opted to complete an overnight Mössbauer study before conducting an overnight APXRS (Alpha Particle X-Ray Spectrometer) study in order to decide how long to stay at this location. Because the Mössbauer spectrum was similar to that of an earlier un-brushed target nicknamed Barnhill, the Team directed the Rover to resume driving after collecting the APXRS data;
Sol 754: Spirit took after-brushing images of Manager with the MI, finished the analysis of Manager with the APXRS, and took PanCam images of Barnhill;
