PHOE-SOL020-024-Changes_v3.jpgEvaporation or Sublimation? Water or CO2? (approximate colors; credits: NASA)54 visiteCaption NASA:" Compare these two close-up pictures taken on Sol 20 (left) and Sol 24 of a trench dug in the Martian surface by NASA's Phoenix Lander. Those Soles of the Phoenix Mission, correspond to June 15 and 18, 2008, on planet Earth. Light-colored, dice-sized chunks, visible in the lower left shadow region of the trench in the Sol 20 image have vanished by Sol 24 -- a strong indication that the chunks were ice uncovered by digging the shallow trench. The vanishing act likely demonstrates the sublimation of ice in the trench, a process similar to evaporation, in which the ice went directly from solid to gas after it was exposed to sunlight and the thin, dry Martian atmosphere".

PHOE-SOL022-PIA10905.jpgSnow-White - Sol 22 (MULTISPECTRUM; credits: Lunexit)54 visiteCaption NASA:"NASA's Phoenix Mars Lander began excavating a new trench, dubbed "Snow White", in a patch of Martian Soil located near the center of a polygonal surface feature, nicknamed "Cheshire Cat".
The trench is about 2 cm (0,8") deep and 30 cm (about 12") long.
The "dump pile" is located at the top of the trench, the side farthest away from the Lander, and has been dubbed "Croquet Ground". The digging site has been named "Wonderland".
At this early stage of digging, the Phoenix team did not expect to find any of the white material seen in the first trench, now called "Dodo-Goldilocks". That trench showed white material at a depth of about 5 cm (approx. 2"). More digging of Snow White is planned for coming Martian Days.
The dark portion of this image is the shadow of the Lander's Solar Panel; the bright areas within this region are not in shadow.
Snow White was dug on Sol 22 (June 17, 2008) with Phoenix's Robotic Arm. This picture was acquired on the same day by the lander's Surface Stereo Imager. This image has been enhanced to brighten shaded areas". MareKromium

PHOE-SOL025-PIA10912.jpgMonochrome Mars: from Viking Lander 2 to Phoenix (approximate colors; credits: NASA)54 visiteCaption NASA:"This color image taken by the Surface Stereo Imager on NASA's Phoenix Mars Lander shows the trench dubbed "Snow White" after further digging on the 25th Martian Day, or Sol, of the mission (June 19, 2008). The Lander's Solar Panel is casting a shadow over a portion of the trench.
The trench is about 5 cm (2") deep and 30 cm (12") long".
Nota Lunexit: sembrano davvero poche le differenze "cromatiche" del suolo Marziano, così come appariva ai tempi del Viking Lander 2 rispetto a Phoenix. Ciò che cambia è l'intensità di fondo (accentuata nel frame Viking 2 - inset), ma la sostanza è sempre la stessa: Marte, secondo la NASA, è un Mondo sostanzialmente monocromatico (arancio, rosso, rosa o verde-giallastro che si voglia). Che tristezza e, soprattutto, che falsità...MareKromium

Il vero "clou" di tutta la questione - quale che sia il materiale che stiamo osservando - probabilmente è in quel dettaglio...MareKromium

PHOE-SOL026-PIA10918.jpgFrom "Bad" to "Worse"... - Sol 2660 visiteIncommentabile: questo frame è stata aggiunto nella Galleria del Planetary Photojournal dedicata a Marte nella notte fra il 1mo ed il 2 Luglio 2008.
E', come ben vedete, il singolo dettaglio del terriccio depositato sullo "scoop" di Phoenix che, per fattura e posizionamento (nel contesto di un altro frame), ci aveva fatto gridare (pubblicamente) al "furto". Ebbene, i nostri Amici di Pasadena (e del Max Planck Institute) che ti fanno? Inseriscono, retrodatandola, la porzione di frame che aveva isolato e colorizzato il Dr Faccin, così da conferirle una (presumiamo) "Autonoma Dignità" e per mostrare che il loro lavoro non era stato una scopiazzatura del nostro.
Ok, allora ci permettiamo di fare due puntualizzazioni:
1) noi controlliamo il Planetary Photojournal ogni giorno e questo frame, sino a ieri sera (h. 23:45 CET - data della nostra ultima lettura del Planetary Photojournal), non c'era (mentre adesso c'è e porta, come data di inserimento, il 26 Giugno u.s. - sic!);
2) questo frame dovrebbe essere parte di un filmatino "Quickmovie" il quale, al momento (h. 12:10 CET), NON E' ancora disponibile sul Planetary Photojournal (e meno male che lo avevano inserito dal 26 di Giugno u.s. (sic, again!).
Morale: i nostri (comunque) Amici di Pasadena, per "salvarsi" da una prima magrissima figura, ne hanno collezionata una seconda... Che tristezza.
Caption NASA:"This pan and zoom animation shows a microscopic view of fine-grained material at the tip of the Robotic Arm scoop as seen by the Robotic Arm Camera (RAC) aboard NASA's Phoenix Mars Lander on June 20, 2008, the 26th Martian Day, or Sol, of the mission.
RAC scientists took this image at a resolution of 30 microns by rotating the scoop to within 11 mm of the camera's front lens and refocusing the camera to macro focus.
The image shows small clumps of fine, fluffy, red soil particles collected in a sample called 'Rosy Red.'.
The sample was dug from the trench named 'Snow White' in the area called 'Wonderland'. Some of the Rosy Red sample was delivered to Phoenix's Optical Microscope and Wet Chemistry Laboratory for analysis.
The RAC provides its own illumination, so the color seen in RAC images is color as seen on Earth, not color as it would appear on Mars.
The image behind the RAC animation, taken by Phoenix's Surface Stereo Imager also on Sol 26, provides context. (See also PIA10921)".MareKromium
