| Ultimi arrivi - From Ashes to Eternity: the Phoenix Mars Mission |
00-PhoenixLiftoff.jpgThe beginning...79 visiteCaption NASA:"Can Mars sustain life? To help answer this question, last week NASA launched the Phoenix Mission to Mars. In May 2008, Phoenix is expected to land in an unexplored North Polar Region of Mars that is rich in water-ice. Although Phoenix cannot move, it can deploy its cameras, robotic arm, and a small chemistry laboratory to inspect, dig, and chemically analyze its landing area. One hope is that Phoenix will be able to discern telling clues to the history of ice and water on Mars. Phoenix is also poised to explore the boundary between ice and soil in hopes of finding clues of a habitable zone there that could support microbial life.
Phoenix has a planned lifetime of 3 months on the Martian surface".MareKromiumAgo 08, 2007

B-PIA09947.jpgContext Image of Planned Landing Site55 visiteCaption NASA:"This view covers an area about 27 Km (about 17 miles) wide within the planned landing area for NASA's Phoenix Mars Lander. It was taken by the Context Camera on NASA's Mars Reconnaissance Orbiter and catalogued as image P02_001893_2485_XI_68N126W_061221 from that instrument.
Note the crater near the top (north) of the image. The red box indicates the position of a higher-resolution image PIA09948 of ground texture in this area".MareKromiumAgo 04, 2007

B-PIA09948.jpgSweet Spot for Landing on Mars71 visiteCaption NASA:"This view shows scattered rocks and a polygonal ground texture within the "sweet spot" of the planned landing area for NASA's Phoenix Mars Lander.
This is a subframe, covering a patch of ground about 250 meters (820 feet) across, from a larger image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on Jan. 1, 2007.
The full image, catalogued as HiRISE image PSP_002170_2485, is centered at 68,3° North Latitude and 232,9° East Longitude".MareKromiumAgo 04, 2007

B-PIA09944.jpgFar-Northern Destination for Phoenix Mars Lander58 visiteCaption NASA:"The planned Landing Site for NASA's Phoenix Mars Lander lies at a latitude on Mars equivalent to Northern Alaska on Earth. It is within the region designated "D" on this global image.
This is an orthographic projection with color-coded elevation contours and shaded relief based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor Orbiter. Total vertical relief is about 28 Km (about 17 miles) from the top of the highest volcano (red) to the Northern Lowlands (blue).
North Pole is where the longitude lines converge".MareKromiumAgo 04, 2007

B-PIA09945.jpgTopographical Context of Phoenix Landing Region55 visiteCaption NASA:"Color coding indicates the topography in this map of the region of Mars from 65 to 72° North Latitude and from 230 to 250° East Longitude. This area was designated "Region D" in the process of evaluating potential Landing Sites for NASA's Phoenix Mars Lander. The location chosen for safe landing sites is within the box bordered with a heavy black line along the western boundary of this region.
Elevation in the region varies from about 3600 meters (11.800 feet) to 4400 meters (14.400 feet) below the zero reference point for Martian Surface Elevation.
The topographical information is from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor Orbiter".MareKromiumAgo 04, 2007

B-PIA09946-1.jpgPossible Landing Ellipses for Phoenix (1)55 visiteCaption NASA:"Launch date makes a difference in the orientation of ellipses marking where NASA's Phoenix Mars Lander will have a high probability of landing, given the planned targeting for the Spring 2008 Landing Site. This map shows possible landing ellipses for the Aug. 3, 2007, opening of the launch period (the ellipse oriented North-West to South-East) and for launch dates at the middle and end of the 3-week period of launch opportunities.
The map also shows a color-coded interpretation of geomorphic units -- categories based on the surface textures and contours. The yellow-coded area surrounding a crater informally named "Heimdall" appears to have even fewer boulders on the surface than other units. The geomorphic mapping is overlaid on a shaded relief map based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor orbiter.
The red box indicates the location of an image PIA09947 from the Context Camera on NASA's Mars Reconnaissance Orbiter".MareKromiumAgo 04, 2007
