TheRings-N00114226-N00114326.gifThe Rings, with "noise", "cosmic rays" and "unknown objects" - GIF Movie (credits: Dr Gianluigi Barca)55 visiteUno splendido filmato GIF il quale, oltre a darci la sensazione visiva del "movimento" degli Anelli (rectius: di Cassini rispetto agli Anelli), ci fornisce un gran numero di esempi di possibili Anomalìe e "disturbi" di segnale.
In tre parole: un Filmato Didattico. Congratulazioni, come sempre, al Dr Barca!
...e per gli Esperti: riuscite a distinguere alcune "Spikes"?MareKromium

PHOE-SOL022-PIA10905.jpgSnow-White - Sol 22 (MULTISPECTRUM; credits: Lunexit)55 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-SOL020-024-Changes_v3.jpgEvaporation or Sublimation? Water or CO2? (approximate colors; credits: NASA)55 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-SOL025-PIA10912.jpgMonochrome Mars: from Viking Lander 2 to Phoenix (approximate colors; credits: NASA)55 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
