OPP-SOL653-1P186154379EFF64KCP2424L2M1-2.jpgA reasonable color for Erebus' Pavings - Sol 653 (False Colors)55 visiteAbbiamo guardato e studiato, nei limiti del possibile e del ragionevole, i frames in "almost e/o approximately true colors" in arrivo da Meridiani.
In realtà, sebbene molti frames - specie i primi - mostrassero la pianura di Meridiani di color rosso o arancione (almeno prevalentemente), adesso la sensazione è che il colore dominante - dati NASA - sia un verdastro scuro, con qualche traccia di arancio pallido e di giallo. E allora, dato che i frames a colori sono sempre (diremmo che sono ormai "per definizione") questionabili, ne abbiamo elaborato anche noi uno.
Tuttavia, nella nostra interpretazione, non si parla nè di colori approssimativamente veri, nè di colori quasi veri.
I colori che proponiamo sono solo colori "ragionevoli": e cioè basati sui dati NASA più recenti e sul buon senso, insomma. Il risultato?

OPP-SOL2453-2454-PIA13794-1.jpgSanta Maria Crater in Natural Colors, according to NASA - Sol 2453 and 2454 (an Image-Mosaic by NASA/JPL-Caltech - Cornell-ASU)130 visiteNASA's Mars Exploration Rover Opportunity is spending the Seventh Anniversary of its landing on Mars investigating a Crater called "Santa Maria", which has a diameter about the length of a football field. This scene looks Eastward across the Crater. Portions of the Rim of a much larger Crater, such as Endeavour Crater, appear on the horizon.
The panorama spans 125 compass degrees, from North/North-West on the left to South/South-West on the right. It has been assembled from multiple frames taken by the PanCam on Opportunity during the 2453rd and 2454th Martian Days, or Soles, of the Rover's work on Mars (such as Dec. 18 and 19, 2010).
Opportunity landed in the Meridiani Planum Region of Mars on Jan. 24, 2004, Universal Time (Jan. 25, Pacific Time) for a mission originally planned to last for three months. Since that Prime Mission, the Rover has continued to work in bonus-time extended missions.
Both Opportunity and its twin, Spirit, have made important discoveries about wet environments on ancient Mars that may have been favorable for supporting microbial life.
By mid-January 2011, Opportunity reached a location at the South-Eastern edge of Santa Maria Crater. The Rover Team developed plans for Opportunity to spend a few weeks investigating rocks at that site during Solar Conjunction, a period when communications between Earth and Mars are curtailed because the Sun is almost directly between the two Planets. After completion of its work at Santa Maria, the Rover will resume a long-term trek toward Endeavour.
This view combines images taken through three different PanCam filters admitting light with wavelengths centered at 753 nanometers (Near InfraRed), 535 nanometers (green) and 432 nanometers (violet). This "Natural Color" is the Rover Team's best estimate of what the scene would look like if we were there and able to see it with our own eyes. Seams have been eliminated from the Sky portion of the mosaic to better simulate the vista a person standing on Mars would see.MareKromium![1](themes/hardwired/images/rate_full.png) ![1](themes/hardwired/images/rate_empty.png) ![1](themes/hardwired/images/rate_empty.png) ![1](themes/hardwired/images/rate_empty.png) ![1](themes/hardwired/images/rate_empty.png) (21 voti)

SOL1369-A-1198865273.jpgSpirit's West Valley Panorama (approx. true colors; credits: NASA)68 visiteForse, tra i panorami colorizzati by NASA e, a nostro avviso, venuti fuori "infelici" (insomma: riusciti male), questa colorizzazione è, in assoluto, fra le tre peggiori.
La NASA è, di fatto, tornata alla "tinteggiatura gialla" che abbiamo visto ai tempi di Pathfinder: una Dominante Cromatica Giallo Ocra densa, piatta ed uniforme, tanto - esteticamente - brutta, quanto - scientificamente - improbabile.
Ma tant'è...
Caption NASA:"NASA'S MER Spirit captured this Westward view from atop a low plateau where Sprit spent the closing months of 2007.
After several months near the base of the plateau called "Home Plate" in the inner basin of the Columbia Hills range inside Gusev Crater, Spirit climbed onto the Eastern edge of the plateau during the Rover's 1306th Martian day, or Sol, (Sept. 5, 2007).
It examined rocks and soils at several locations on the Southern half of Home Plate during September and October.
It was perched near the western edge of Home Plate when it used its panoramic camera (Pancam) to take the images used in this view on sols 1,366 through 1,369 (Nov. 6 through Nov. 6, 2007). With its daily solar-energy supply shrinking as Martian summer turned to fall, Spirit then drove to the northern edge of Home Plate for a favorable winter haven. The rover reached that northward-tilting site in December, in time for the fourth Earth-year anniversary of its landing on Mars. Spirit reached Mars on Jan. 4, 2004, Universal Time (Jan. 3, 2004, Pacific Standard Time). It landed at a site at about the center of the horizon in this image.
This panorama covers a scene spanning left to right from southwest to northeast. The western edge of Home Plate is in the foreground, generally lighter in tone than the more distant parts of the scene. A rock-dotted hill in the middle distance across the left third of the image is "Tsiolkovski Ridge," about 30 meters or 100 feet from the edge of Home Plate and about that same distance across. A bump on the horizon above the left edge of Tsiolkovski Ridge is "Grissom Hill," about 8 kilometers or 5 miles away. At right, the highest point of the horizon is "Husband Hill," to the north and about 800 meters or half a mile away.
This view combines separate images taken through Pancam filters centered on wavelengths of 753 nanometers, 535 nanometers and 432 nanometers to produce an approximately true-color panorama".MareKromium![1](themes/hardwired/images/rate_full.png) ![1](themes/hardwired/images/rate_empty.png) ![1](themes/hardwired/images/rate_empty.png) ![1](themes/hardwired/images/rate_empty.png) ![1](themes/hardwired/images/rate_empty.png) (21 voti)
