PHOE-SOL000-HIRISE.jpgThe Descent of Phoenix, from MRO - Sol 056 visiteCaption NASA:"NASA's Mars Phoenix Lander can be seen parachuting down to Mars, in this image captured by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. This is the first time that a spacecraft has imaged the final descent of another spacecraft onto a planetary body.
From a distance of about 310 Km (193 miles) above the surface of the Red Planet, Mars Reconnaissance Orbiter pointed its HiRISE obliquely toward Phoenix shortly after it opened its parachute while descending through the Martian Atmosphere. The image reveals an apparent 10-meter-wide (30-foot-wide) parachute fully inflated. The bright pixels below the parachute show a dangling Phoenix. The image faintly detects the chords attaching the backshell and parachute. The surroundings look dark, but correspond to the fully illuminated Martian surface, which is much darker than the parachute and backshell.
Phoenix released its parachute at an altitude of about 12,6 Km (7,8 miles) and a velocity of 1.7 times the speed of sound".MareKromiumMag 27, 2008

PHOE-SOL001-N-P-Pstcd.jpgVastitas Borealis - Sol 1 (RAW Color Data; credits: Dr Gianluigi Barca)55 visiteAnche questa splendida elaborazione in colori RAW, realizzata dall'ottimo Dr Gianluigi Barca finirà con l'assomigliare molto - a nostro parere - alle elaborazioni NASA in "false" ed "approximate true colors".
Staremo a vedere... MareKromiumMag 26, 2008

PHOE-SOL001-PIA10682.jpgThe soil of Vastitas Borealis - Sol 1 (Approximate Colors; credits: NASA/JPL-Caltech/University of Arizona )55 visiteCaption NASA:"This image shows a polygonal pattern in the ground near NASA's Phoenix Mars Lander, similar in appearance to icy ground in the arctic regions of Earth.
Phoenix touched down on the Red Planet at 4:53 p.m. Pacific Time (7:53 p.m. Eastern Time), May 25, 2008, in an arctic region called Vastitas Borealis, at 68° North Latitude and 234° East Longitude.
This is an approximate-color image taken shortly after landing by the spacecraft's Surface Stereo Imager, inferred from two color filters, a violet, 450-nanometer filter and an infrared, 750-nanometer filter".
Nota Lunexit: una nuova "dizione" NASA. Ora questi (semi-assurdi) colori non sono più Approximate True o Approximate Natural: adesso sono SOLO "Approximate".
Beh, visti i quattrini, i mezzi, le tecnologie, le menti ed il tempo che si ritrovano a disposizione i nostri Amici di Pasadena, scusateci se, dopo aver visto questa (a nostro parere "quasi inguardabile") elaborazione, non ci sentiamo di fargli i complimenti...MareKromiumMag 26, 2008

PHOE-SOL001-PIA10690.jpgVastitas Borealis - Sol 1 (Approximate True Colors; credits: NASA/JPL-Caltech/University of Arizona )55 visiteVisto?!?...Le "colorizzazioni" NASA? Prevedibili. Sempre prevedibili.
Prevedibili in maniera quasi sconcertante: dai cieli "rosati" (che abbiamo già visto sopra Gusev Crater e, sebbene più raramente, sopra Meridiani Planum) al terreno pallidamente arancio-giallo. E questa è la prima immagine "colorata"! Chissà le altre...
Caption NASA:"This image, one of the first captured by NASA's Phoenix Mars Lander, shows the vast plains of the northern polar region of Mars. The flat landscape is strewn with tiny pebbles and shows polygonal cracking, a pattern seen widely in Martian high latitudes and also observed in permafrost terrains on Earth. The polygonal cracking is believed to have resulted from seasonal freezing and thawing of surface ice.
