Caption NASA:"Typical view if you were standing on Mars and slowly turned around for a look. Starting at the North, SSI sees its shadow and turns its head viewing Solar Arrays, the Lander Deck and landscape. Note very few rocks on the hummocky terrain and network of troughs, typical of Polar Surfaces here on Earth".MareKromium

B-PIA09947.jpgContext Image of Planned Landing Site61 visiteCaption NASA:"This view covers an area about 27 Km (about 17 miles) wide within the planned landing area for NASA's Phoenix Mars Lander. It was taken by the Context Camera on NASA's Mars Reconnaissance Orbiter and catalogued as image P02_001893_2485_XI_68N126W_061221 from that instrument.
Note the crater near the top (north) of the image. The red box indicates the position of a higher-resolution image PIA09948 of ground texture in this area".MareKromium

B-PIA09944.jpgFar-Northern Destination for Phoenix Mars Lander65 visiteCaption NASA:"The planned Landing Site for NASA's Phoenix Mars Lander lies at a latitude on Mars equivalent to Northern Alaska on Earth. It is within the region designated "D" on this global image.
This is an orthographic projection with color-coded elevation contours and shaded relief based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor Orbiter. Total vertical relief is about 28 Km (about 17 miles) from the top of the highest volcano (red) to the Northern Lowlands (blue).
North Pole is where the longitude lines converge".MareKromium

B-PIA09946-1.jpgPossible Landing Ellipses for Phoenix (1)63 visiteCaption NASA:"Launch date makes a difference in the orientation of ellipses marking where NASA's Phoenix Mars Lander will have a high probability of landing, given the planned targeting for the Spring 2008 Landing Site. This map shows possible landing ellipses for the Aug. 3, 2007, opening of the launch period (the ellipse oriented North-West to South-East) and for launch dates at the middle and end of the 3-week period of launch opportunities.
The map also shows a color-coded interpretation of geomorphic units -- categories based on the surface textures and contours. The yellow-coded area surrounding a crater informally named "Heimdall" appears to have even fewer boulders on the surface than other units. The geomorphic mapping is overlaid on a shaded relief map based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor orbiter.
The red box indicates the location of an image PIA09947 from the Context Camera on NASA's Mars Reconnaissance Orbiter".MareKromium

PHOE-SOL097-PIA11074.jpgDOES "NASA" READ US? - Sol 9762 visite...O forse siamo soltanto "bravi"?!? I "granuli" che il Dr Faccin per primo - e praticamente da subito - aveva notato essere presenti su una delle zampe del Lander, adesso - e SOLO dopo 97 Soles... - sono stati notati anche dalla NASA la quale, pochi giorni dopo una delle nostre usuali pubblicazioni che esprimono dubbi e curiositā, interviene pesantemente su queste features dedicandogli un frame e qualche parola sul Planetary Photojournal.
Coincidenza (l'ennesima)? Causualitā (l'ennesima)? Fortuna (si, certo, come no...)? La risposta č ardua. O forse no.
La risposta č semplicissima e, a parere ci chi scrive, potrebbe essere "nascosta" nella nostra stessa "Lista Utenti".
E comunque sia, c'č di che essere fieri!
Caption NASA:"The Robotic Arm Camera on NASA's Phoenix Mars Lander took this image on Sept. 1, 2008, at about 04:00 M.L.T., during the 97th Martian Day, or Sol, since landing.
The view underneath the Lander shows growth of the clumps adhering to leg strut (upper left) compared with what was present when a similar image was taken about three months earlier (see PIA10759).
The view in this Sol 97 image is southward. Illumination is from the early morning Sun above the North-Eastern horizon. This is quite different from the illumination in the Sol 8 image, which was taken in mid-afternoon.
The science team has discussed various possible explanations for these clumps.
One suggestion is that they may have started from a splash of mud if Phoenix's descent engines melted icy soil during the landing.
Another is that specks of salt may have landed on the strut and began attracting atmospheric moisture that freezes and accumulates.
The clumps are concentrated on the north side of the strut, usually in the shade, so their accumulation could be a consequence of the fact that condensation favors colder surfaces.
In this image, compared with the one from three months earlier, the flat, smooth patches of ice exposed underneath the lander seem to be partly covered by darker material left behind as ice vaporizes away.
The flat patch in the center of the image has the informal name "Holy Cow", based on researchers' reaction when they saw the initial image of it".
Nota Lunexit: "Holy Cow", tradotto in Italiano, significa "Caspita!!!"MareKromium

PHOE-SOL099-PIA11073.jpgPhoenix Conductivity Probe after Extraction - Sol 99 (natural colors; credits: NASA)90 visiteCaption NASA:"NASA's Phoenix Mars Lander inserted the 4 needles of its Thermal and Conductivity Probe into Martian soil during the 98th Sol of the mission and left it in place until Sol 99 (Sept. 4, 2008).
The Surface Stereo Imager on Phoenix took this image on the morning of Sol 99 after the probe was lifted away from the soil. This imaging served as a check of whether soil had stuck to the needles.
The Thermal and Conductivity Probe measures how fast heat and electricity move from one needle to an adjacent one through the soil or air between the needles. Conductivity readings can be indicators about water vapor, water ice and liquid water.
The probe is part of Phoenix's Microscopy, Electrochemistry and Conductivity suite of instruments".MareKromium
