PIA05484: Opportunity Spies "Endurance" on the Horizon

This image taken by the Mars Exploration Rover Opportunity's panoramic camera shows the eastern plains that stretch beyond the small crater where the rover landed. In the distance, the rim of a larger crater dubbed "Endurance" can be seen.
This color mosaic was taken on the 32nd martian day, or sol, of the rover's mission and spans 20 degrees of the horizon. It was taken while Opportunity was parked at the north end of the outcrop, in front of the rock region dubbed "El Capitan" and facing east.

The features seen at the horizon are the near and far rims of "Endurance," the largest crater within about 6 kilometers (4 miles) of the lander. Using orbital data from the Mars Orbiter Camera on NASA's Mars Global Surveyor spacecraft, scientists estimated the crater to be 160 meters (175 yards) in diameter, and about 720 meters (half a mile) away from the lander.

The highest point visible on "Endurance" is the highest point on the far wall of the crater; the sun is illuminating the inside of the far wall.

Between the location where the image was taken at "El Capitan" and "Endurance" are the flat, smooth Meridiani plains, which scientists believe are blanketed in the iron-bearing mineral called hematite. The dark horizontal feature near the bottom of the picture is a small, five-meter (16-feet) crater, only 50 meters (164 feet) from Opportunity's present position. When the rover leaves the crater some 2 to 3 weeks from now, "Endurance" is one of several potential destinations.

PIA05482: Ripples in Rocks Point to Water

This image taken by the Mars Exploration Rover Opportunity's panoramic camera shows the rock nicknamed "Last Chance," which lies within the outcrop near the rover's landing site at Meridiani Planum, Mars. The image provides evidence for a geologic feature known as ripple cross-stratification. At the base of the rock, layers can be seen dipping downward to the right. The bedding that contains these dipping layers is only one to two centimeters (0.4 to 0.8 inches) thick. In the upper right corner of the rock, layers also dip to the right, but exhibit a weak "concave-up" geometry. These two features -- the thin, cross-stratified bedding combined with the possible concave geometry -- suggest small ripples with sinuous crest lines. Although wind can produce ripples, they rarely have sinuous crest lines and never form steep, dipping layers at this small scale. The most probable explanation for these ripples is that they were formed in the presence of moving water.

PIA05492: "El Capitan's" Scientific Gems

This mosaic of images taken by the panoramic camera onboard the Mars Exploration Rover Opportunity shows the rock region dubbed "El Capitan," which lies within the larger outcrop near the rover's landing site. "El Capitan" is being studied in great detail using the scientific instruments on the rover's arm; images from the panoramic camera help scientists choose the locations for this compositional work. The millimeter-scale detail of the lamination covering these rocks can be seen. The face of the rock to the right of the mosaic may be a future target for grinding with the rover's rock abrasion tool.

PIA05509:Seeing Red at Guadalupe

This image from the Mars Exploration Rover Opportunity's panoramic camera shows the results of the second drilling by the rock abrasion tool, located on the rover's instrument deployment device, or "arm." The drilling took place on a target called "Guadalupe" within the "El Capitan" region of the Meridiani Planum, Mars, rock outcrop.
As with the first rock abrasion tool target called "McKittrick," the grinding process at "Guadalupe" has generated a significant amount of fine-grained, reddish dust. Color and spectral properties of the dust show that it may contain some fine-grained crystalline red hematite. This image is an enhanced color composite generated from three different panoramic camera filters.

PIA05510: Messy Grind

This image shows the results of the Mars Exploration Rover Opportunity's grinding of its first target with the rock abrasion tool, located on its instrument deployment device, or "arm." The target, called "McKittrick," is located on the "El Capitan" region of the rock outcrop at Meridiani Planum, Mars.
The grinding process at "McKittrick" has generated a significant amount of fine-grained, reddish dust. Color and spectral properties of the dust show that it may contain some fine-grained crystalline red hematite. This image is an enhanced color composite generated from three different panoramic camera filters.

PIA05514: Opportunity's Heatshield on the Horizon

This image mosaic from the panoramic camera on the Mars Exploration Rover Opportunity shows the distant horizon from Opportunity's position inside a small crater at Meridiani Planum, Mars. To the left is a large crater about 700 meters (2,296 feet) away from the landing site and approximately 200 meters (656 feet) in diameter. In the center, Opportunity's heatshield and its impact mark can be seen at a distance of approximately 875 meters (one-half mile) from the landing site. To the right, a string of bounce marks left by the rover's airbags is visible. Near the mark just outside the landing site crater's rim is the largest rock in the area. This rock is about 40 centimeters (16 inches) across and 50 meters (164 feet) from the rover's position. The image is an enhanced color composite acquired on the 35th and 36th martian days, or sols, of Opportunity's journey, using three different wavelength filters.

PIA05584:'Berries' and Rock Share Common Origins

This false-color composite image, taken at a region of the rock outcrop dubbed "Shoemaker's Patio" near the Mars Exploration Rover Opportunity's landing site, shows finely layered sediments, which have been accentuated by erosion. The sphere-like grains or "blueberries" distributed throughout the outcrop can be seen lining up with individual layers. This observation indicates that the spherules are geologic features called concretions, which form in pre-existing wet sediments. Other sphere-like grains, such as impact spherules or volcanic lapilli (fragments of material etween 2 and 64 millimeters or .08 and 2.5 inches in maximum dimension that are ejected from a volcano) are thought to be deposited with sediments and thus would form layers distinct from those of the rocks. This image was captured by the rover's panoramic camera on the 50th martian day, or sol, of the mission. Data from the camera's infrared, green and violet filters were used to create this false-color picture.

PIA05588: 'Berries' Here, There, Everywhere

This approximate true-color image suggests that the plains beyond the small crater where the Mars Exploration Rover Opportunity now sits are littered with the same dark grey material found inside the crater in the form of spherules or "blueberries." Because Mars orbiters have observed the iron-bearing mineral hematite across these plains, scientists hypothesize that the blueberries are also made up of this mineral. This image was taken by the rover's panoramic camera on the 17th martian day, or sol, of its mission. Data from the camera's red, green and blue filters were combined to create this image.

PIA05634: Discovery Served Up in a Bowl

This image from the Mars Exploration Rover Opportunity's panoramic camera is an approximate true-color rendering of the exceptional rock called "Berry Bowl" in the "Eagle Crater" outcrop. The study of this "blueberry-strewn" area and the identification of hematite as the major iron-bearing element within these sphere-like grains helped scientists confirm their hypothesis that the hematite in these martian spherules was deposited in water. To separately analyze the mineralogical content of three main features within this area -- blueberries, dust and rock -- it was important that the rock abrasion tool's brush was able to rest on a relatively berry-free spot. The rock's small size and crowd of berries made the 10-minute brushing a challenge to plan and execute. The successful brushing on the target whimsically referred to as "Near Empty" on the rover's 48th sol on Mars left a dust-free impression for subsequent examination by the rover's spectrometers. No grinding was necessary on the rock because spectral data obtained on the dust-free surface were sufficient to verify that the rock's chemical composition differs significantly from the hematite-rich berries.

Rock on the Range

This mosaic of images from the Mars Exploration Rover Opportunity panoramic camera looks to the southeast from inside Eagle Crater. This was among the first peeks out into the plains, revealing the enigmatic dark feature dubbed "Bounce" rock, seen on the left side of the mosaic. This feature is right next to one of the large bounce marks that the airbag-packaged rover made as it was bouncing across the plains during landing. This enhanced color mosaic was made on sol 36 from the camera's the infrared (750 nanometer), green (530 nanometer), and violet (430 nanometer) filters.

PIA05678: Bounce Rock Snapshot

This Mars Exploration Rover Opportunity panoramic camera image shows "Bounce Rock," a rock the airbag-packaged rover struck while rolling to a stop on January 24, 2004. This is the largest rock for as far as the eye can see, approximately 35 centimeters (14 inches) long and 10 centimeters (4 inches) high. There appears to be a dusty coating on the top of parts of the rock, which may have been broken when it was struck by the airbags. The rock was about 5 meters (16 feet) from the rover when this image was obtained. This is an enhanced color composite image from sol 36 of the rover's journey, generated using the camera's L2 (750 nanometer), L5 (530 nanometer), and L6 (480 nanometer) filters.

PIA05731: 'Bounce' Exposed

This approximate true-color image, acquired by the Mars Exploration Rover Opportunity's panoramic camera, features the hole ground by the rover's rock abrasion tool into "Bounce" rock. The hole measures approximately 35 centimeters (14 inches) long and 10 centimeters (4 inches) high. The depression measures 6.44 millimeters (0.25 inch) deep and about 4.5 centimeters (1.7 inches) across. The grinding procedure took place on the rover's 66th sol on Mars and lasted 2 hours and 15 minutes. A combination of limited solar power, added safety measures and the rock's jagged texture led the rock abrasion tool team to set more aggressive grinding parameters to ensure that the end result was a full circle, suitable for a thorough read from the rover's spectrometers.

Bounce's outer ring consists of the cuttings from the rock, pushed out by the brushes on the grinding instrument. The small impressions filled with red dust on the outer ring were caused by the instrument's contact mechanism, which serves to stabilize it while grinding.

This image was created using the panoramic camera's blue, green and red filters.

PIA05828: Trench Reveals Two Faces of Soils
This approximate true-color image mosaic from the panoramic camera on the Mars Exploration Rover Opportunity shows a trench dug by the rover in the vicinity of the "Anatolia" region. Two imprints from the rover's Mossbauer spectrometer instrument were left in the exposed soils. Detailed comparisons between soils exposed at the surface and those found at depth reveal that surface soils have higher levels of hematite while subsurface soils show fine particles derived from basalt. The trench is approximately 11 centimeters deep. This image was taken on sol 81 with the panoramic camera's 430-, 530- and 750-nanometer filters.

PIA05829: Similar on the Inside (pre-grinding)

This approximate true-color image taken by the panoramic camera on the Mars Exploration Rover Opportunity show the rock called "ilbara" located in the small crater dubbed "Fram." The rock appears to be dotted with the same "blueberries," or spherules, found at "Eagle Crater." Spirit drilled into this rock with its rock abrasion tool. After analyzing the hole with the rover's scientific instruments, scientists concluded that Pilbara has a similar chemical make-up, and thus watery past, to rocks studied at Eagle Crater. This image was taken with the panoramic camera's 480-, 530- and 600-nanometer filters.
