				<title>Phoenix Trenches, Stereo</title>
				<link>http://phoenix.lpl.arizona.edu/images.php?gID=39078&amp;cID=152</link>
				<description>Here is a stereo, panoramic  view of various trenches dug by NASA's Phoenix Mars Lander. The images that make up this panorama were taken by Phoenix's Surface Stereo Imager at about 4 p.m., local solar time at the landing site, on the 131st, Martian day, or sol, of the mission (Oct. 7, 2008).

For scale, the &quot;Pet Donkey&quot; trench just to the right of center is approximately 38 centimeters (15 inches) long and 31 to 34 centimeters (12 to 13 inches) wide. In addition, the rock in front of it, &quot;Headless,&quot; is about 11.5 by 8.5 centimeters (4.5 by 3.3 inches), and about 5 centimeters (2 inches) tall.

This image appears three-dimensional when viewed through blue-red glasses.

The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

				<title>Phoenix's La Manch Trench in 3D</title>
				<link>http://phoenix.lpl.arizona.edu/images.php?gID=38737&amp;cID=152</link>
				<description>This anaglyph, taken by NASA's Phoenix Mars Lander's Surface Stereo Imager, was taken on the 131st Martian day, or sol, of the mission (Oct. 7, 2008). The anaglyph highlights the depth of the trench, informally named &quot;La Mancha,&quot; and reveals the ice layer beneath the soil surface. The trench's depth is about 5 centimeters deep.

The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

				<title>Preparation for Moving a Rock on Mars, Stereo View</title>
				<link>http://phoenix.lpl.arizona.edu/images.php?gID=34531&amp;cID=152</link>
				<description>The robotic arm on NASA's Phoenix Mars Lander enlarged a trench beside a rock called &quot;Headless&quot; during the mission's 115th Martian day (Sept. 20, 2008) in preparation for sliding the rock into the trench. The lander's Surface Stereo Imager took this image later that afternoon, showing the enlarged trench and the rock.

The robotic arm successfully moved the rock two days later.

The Phoenix science team sought to move the rock in order to study the soil and the depth to subsurface ice underneath where the rock had been.  

Headless is about the size and shape of a VHS videotape. The trench, called &quot;Neverland,&quot; was excavated to about 3 centimeters (1.2 inches) deep near the rock. The ground surface between the rock and the lip of the trench slopes downward about 3 degrees toward the trench. 

This image was taken at about 4:35 p.m., local solar time on Mars. The view is to the north northeast of the lander.

				<title>Rock Moved by Mars Lander Arm, Stereo</title>
				<link>http://phoenix.lpl.arizona.edu/images.php?gID=34530&amp;cID=152</link>
				<description>The robotic arm on NASA's Phoenix Mars Lander slid a rock out of the way during the mission's 117th Martian day (Sept. 22, 2008) to gain access to soil that had been underneath the rock.The lander's Surface Stereo Imager took the two images for this stereo view later the same day, showing the rock, called &quot;Headless,&quot; after the arm pushed it about 40 centimeters (16 inches) from its previous location.

&quot;The rock ended up exactly where we intended it to,&quot; said Matt Robinson of NASA's Jet Propulsion Laboratory, robotic arm flight software lead for the Phoenix team.

The arm had enlarged the trench near Headless two days earlier in preparation for sliding the rock into the trench. The trench was dug to about 3 centimeters (1.2 inches) deep. The ground surface between the rock's prior position and the lip of the trench had a slope of about 3 degrees downward toward the trench. Headless is about the size and shape of a VHS videotape.

The Phoenix science team sought to move the rock in order to study the soil and the depth to subsurface ice underneath where the rock had been.

This left-eye and right-eye images for this stereo view were taken at about 12:30 p.m., local solar time on Mars. The scene appears three-dimensional when seen through blue-red glasses.The view is to the north northeast of the lander. 

The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by JPL, Pasadena, Calif. Spacecraft development was by Lockheed Martin Space Systems, Denver.

				<title>Picking up Clues from the Discard Pile (Stereo) </title>
				<link>http://phoenix.lpl.arizona.edu/images.php?gID=25825&amp;cID=152</link>
				<description>As NASA's Phoenix Mars Lander excavates trenches, it also builds piles with most of the material scooped from the holes. The piles, like this one called &quot;Caterpillar,&quot; provide researchers some information about the soil.
On Aug. 24, 2008, during the late afternoon of the 88th Martian day after landing, Phoenix's Surface Stereo Imager took separate exposures through its left eye and right eye that have been combined into this stereo view. The image appears three dimensional when seen through red-blue glasses.
This conical pile of soil is about 10 centimeters (4 inches) tall. The sources of material that the robotic arm has dropped onto the Caterpillar pile have included the &quot;Dodo&quot; and &quot;&quot;Upper Cupboard&quot; trenches and, more recently, the deeper &quot;Stone Soup&quot; trench.
Observations of the pile provide information, such as the slope of the cone and the textures of the soil, that helps scientists understand properties of material excavated from the trenches.
For the Stone Soup trench in particular, which is about 18 centimeters (7 inches) deep, the bottom of the trench is in shadow and more difficult to observe than other trenches that Phoenix has dug. The Phoenix team obtained spectral clues about the composition of material from the bottom of Stone Soup by photographing Caterpillar through 15 different filters of the Surface Stereo Imager when the pile was covered in freshly excavated material from the trench.
The spectral observation did not produce any sign of water-ice, just typical soil for the site. However, the bigger clumps do show a platy texture that could be consistent with elevated concentration of salts in the soil from deep in Stone Soup. The team chose that location as the source for a soil sample to be analyzed in the lander's wet chemistry laboratory, which can identify soluble salts in the soil.</description><enclosure url="http://phoenix.lpl.arizona.edu/images/gallery/sm_25825.jpg" type='image/jpeg' />	</item>

				<title>Deep 'Stone Soup' Trenching by Phoenix (Stereo)</title>
				<link>http://phoenix.lpl.arizona.edu/images.php?gID=24925&amp;cID=152</link>
				<description>Digging by NASA's Phoenix Mars Lander on Aug. 23, 2008, during the 88th sol (Martian day) since landing, reached a depth about three times greater than in any trench Phoenix has excavated. The deep trench, informally called &quot;Stone Soup&quot; is at the borderline between two of the polygon-shaped hummocks that characterize the arctic plain where Phoenix landed.

Stone Soup is in the center foreground of this stereo view, which appears three dimensional when seen through red-blue glasses. The view combines left-eye and right-eye images taken by the lander's Surface Stereo Imager on Sol 88 after the day's digging. The trench is about 25 centimeters (10 inches) wide and about 18 centimeters (7 inches) deep.

When digging trenches near polygon centers, Phoenix has hit a layer of icy soil, as hard as concrete, about 5 centimeters or 2 inches beneath the ground surface. In the Stone Soup trench at a polygon margin, the digging has not yet hit an icy layer like that.

Stone Soup is toward the left, or west, end of the robotic arm's work area on the north side of the lander.
