ZM-SOL324_travMOC-A332R1.jpgSpirit's Route in Black and White211 visiteCaption NASA originale:"The Mars Orbital Camera on NASA's Mars Global Surveyor spacecraft took this image of the topography traversed by NASA's Mars Exploration Rover Spirit in months prior to the rover's 318th Sol (Dec. 4, 2004). The yellow line traces the rover's path up to and across the "West Spur" of the Columbia Hills".

ZN-SOL343-Spirit_travmap_GeoDEM_2-A350R1.jpgThe path of Spirit up to Sol 343201 visiteCaption NASA originale:"As NASA's Mars Exploration Rover Spirit continues to explore the "Columbia Hills" within Gusaev Crater, scientists are planning to take a closer look for layered rocks in a steep valley straight ahead before directing the rover to turn south toward the summit of "Husband Hill." Two of the geologic formations the six-wheeled robotic geologist has discovered during 2004 are shown here. One is labeled "Columbia Hills material," representing bedrock of the higher slopes and peaks, and one is labeled "transition zone material," representing rocks that are gradational in character and composition between the hills to the east and the plains to the west. The map also shows Spirit's line of travel through the rover's 344th Sol (Dec. 21, 2004), beginning on the left edge at about the 182nd Sol (July 7, 2004)".

ZO-SPIRIT-SOL354_MERA_MOC-A357R1.jpgApproaching an "overlook"209 visiteThe path of NASA's Mars Exploration Rover Spirit through the rover's 354th martian day, or sol (Dec. 31, 2004), plus some future travel options, are indicated on this map of the "Husband Hill" region of the "Columbia Hills" within Mars' Gusev Crater. The rover team plans to send Spirit to a vantage point dubbed "Larry's Lookout" for views to help in deciding whether to dip into "Tennessee Valley."
The base image for the map was taken by the Mars Orbiter Camera aboard NASA's Mars Global Surveyor.

ZO-T-MERA_Traverse_Map_Sol_404-A408R1_br2.jpgThe "march" of Spirit up to Sol 404217 visiteCaption NASA originale:"NASA's Mars Exploration Rover Spirit drove a total of 4.143 meters (about 2,57 miles) between its landing in January 2004 and its 404th Sol (Feb. 20, 2005). This map on an image taken by the Mars Orbiter Camera on NASA's Mars Global Surveyor shows the course the Rover drove during that time. The Rover has recently been approaching a ridge overlooking "Tennessee Valley" on the north flank of "Husband Hill".

ZO-U-PIA07849_fig1.jpgThe path of Spirit up to Sol 450220 visiteAncora una Mappa - ottenuta grazie ad immagini MGS - che ci ricorda e spiega il viaggio di Spirit, dal momento del Landing (Columbia Memorial Station), al transito accanto al sempre più enigmatico Cratere Bonneville (a proposito: fate caso all'estrema definizione e relative dimensioni - colte da un'altezza di quasi 300 Km! - del 'presunto Heat-Shield' che giace sul bordo del Cratere ad ore 12 e poi provate a rileggerVi la dissertazione "Space Heat Shields" del Dr Feltri nella Sezione "Investigations"...), attraverso la distesa di rocce laviche chiamata Santa Anita e sino all'ascesa sulla Collina Husband, passando attraverso il West Spur (update Sol 450).
Il "riassunto" della marcia di Spirit, ottenuto con questo tipo di grafica, è davvero suggestivo ed agevolmente leggibile anche per chi, pur non essendo esperto di mappe e planimetrie, volesse solo farsi un'idea della geografia della zona che Spirit, da oltre un anno, sta visitando.

ZO-V-PIA07850_fig1.jpgThe path of Spirit up to Sol 450204 visiteCaption NASA originale:"This orbital view shows the path of Spirit's trek through the "Columbia Hills," beginning on the "West Spur" on Sol 156 (June 11, 2004) and continuing up the flanks of "Husband Hill." The dashed line indicates the perimeter of the Columbia Hills, which consist of older rocks of different composition than those of the surrounding plain. The path of Spirit's trek is overlain on imagery from the Mars Orbiter Camera on NASA's Mars Global Surveyor. The 500-meter scale bar is equivalent to 1.640 feet".

ZO-W-PIA07848.jpgColumbia Hills' elevation map from MGS191 visiteThis elevation map shows the region of the Columbia Hills where Rover Spirit has been working since mid-2004. Areas colored blue are lower in elevation while areas colored yellow are higher.
The map imagery is from the MOC on NASA's MGS orbiter.
More than 15 months after landing on Mars, the Spirit rover is still going strong, having traveled a total of 4.276 mt as of Sol 450 (April 8, 2005). This elevation map shows the traverse followed by Spirit since arriving at the "Columbia Hills" in June, 2004.
The blue area at the foot of the Columbia Hills is approximately 20 mt higher in elevation than the site where Spirit landed in Gusev Crater. The highest peak is on the order of 80 mt higher still".

ZO-X-PIA07851_fig1.jpgColumbia Hills' Perspective View (from MGS)205 visiteCaption NASA originale:"This perspective view of a 3D terrain model shows the shape of the "Columbia Hills" landscape where NASA's Mars Exploration Rover Spirit has been working since mid-2004.
North is toward the lower left.
Husband Hill is at the center, with the Inner Basin behind it. This view is from images taken by the Mars Orbiter Camera on NASA's Mars Global Surveyor and processed into a 3D terrain model by the U.S. Geological Survey - USGS".

ZO-YYYY-ZZ-S12-00095m25annot.JPGMOC2-1331a: cPROTO image, 2 November 2005 - Where's "MER Spirit"? (1)182 visiteOriginal caption:"Two years ago, the Mars Exploration Rover (MER), Spirit, touched down in Gusev Crater. The Rover marked its first Mars-year (687 Earth Days) anniversary in November 2005. Shortly before its Martian Anniversary, the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) Team acquired an image covering approximately 3 by 3 Km (such as about 1,9 by 1,9 mi) centered on the Rover's current location in the Columbia Hills.
This first picture (MOC2-1331a) shows the 2 November 2005 image with a spatial resolution of about 50 cm (~1.6 feet) per pixel.
The white box indicates the location of the view in the second picture (MOC2-1331c). (...)
The largest or tallest peak that you can see here is that of Husband Hill: the one that was climbed by the Spirit rover during much of 2005".

ZP-A-S1200095MERA100.JPGMOC2-1331c: Spirit Location, 2 November 2005 - Where's "MER Spirit"? (2)168 visiteOriginal caption:"This picture (MOC2-1331c) shows the Spirit Rover at its 2 November 2005 (Sol 652) location.
Dr. Timothy J. Parker of the MER Team at the NASA/Caltech Jet Propulsion Laboratory confirmed the location of the Rover in the MOC image.
The Region South (toward the bottom) of these images shows the area where the Rover is currently headed.
The large dark patch and other similar dark patches in these images are accumulations of windblown sand and granules".

ZP-B-R131467_S1200095loc.JPGMOC2-1331d: A "before" image from January 2004 (left) and the Rover image from November 2005 (right) - Where's "MER Spirit"? (3)185 visiteOriginal caption:"This picture (MOC2-1331d) shows the location of the Rover in the 2 November 2005 image (S12-00095) inside a white circle. This is compared with the view taken on 10 January 2004 in R13-01467. Back on 10 January 2004, very few ever dreamed that the Rover would ever reach the Columbia Hills.
A Mars year later, the Rover was at the Summit and then headed down the other side of the Hills".
Location near: 14,8° S; 184,6° W
MOC2-1331a Image width: ~3 Km (~1,9 mi);
MOC2-1331d 50 mt scale bar = 164 ft
Illumination from: left
Season: Southern Summer in both R13-01467 and S12-00095
