OPP-SOL952-site_B76_275_navcam_CYL_L-B953R1-1.jpgVictoria Crater, from Duck Bay (1)55 visiteCaption NASA originale:"NASA's Mars Rover Opportunity edged 3,7 meters (12 feet) closer to the top of the Duck Bay alcove along the rim of Victoria Crater during the Rover's 952nd Martian day, or Sol (overnight Sept. 27 to Sept. 28), and gained this vista of the Crater. (...)
The far side of the crater is about 800 mt (one-half mile) away.
The rim of the crater is composed of alternating promontories, rocky points towering approximately 70 mt (about 230 feet) above the crater floor, and recessed alcoves, such as Duck Bay. The bottom of the crater is covered by sand that has been shaped into ripples by the Martian wind.
The rocky cliffs in the foreground have been informally named Cape Verde, on the left, and Cabo Frio, on the right".

R-PIA08788-1.jpgOlympia Undae (1)55 visiteThe Compact Reconnaissance Imaging Spectrometer for Mars, a mineral mapping instrument on NASA's Mars Reconnaissance Orbiter (CRISM), began observing Mars after its lens cover was opened on Sept. 27, 2006.
This image shows one of the first regions of Mars measured after CRISM's cover was opened.
CRISM takes images in two basic formats. The first format is a "targeted image" about 10 by 10 Km (about 6 by 6 miles), at about 18 mt (60 feet) per pixel, in 544 colors covering wavelengths of 0,36 to 3,92 micrometers. The second format is a lower-resolution strip 10 Km (about 6 miles) wide and thousands of kilometers long, at 200 mt (660 feet) per pixel, in 72 colors. Many thousands of these "multispectral survey" strips are used to build a global map.
The image is part of the second multispectral survey strip, taken at 22:36 UTC (6:36 p.m. EDT) on Sept. 27, 2006. Only minimal processing of the data has been done at this early point in the MRO's Mission.
The strip crosses part of the north polar region named Olympia Undae, and stretches between 76.7 north latitude, 141.9 east longitude and 85.5 north, 115.8 east. From the top, the northern end of the image crosses layers of dusty and clean ice in the north polar cap. Moving south the image covers dusty sedimentary deposits, dark sand dunes, and outlying polar ice deposits.
