2. Five Bites Into Mars NASA's Mars rover Curiosity used a mechanism on its robotic arm to dig up five scoopfuls of material from a patch of dusty sand called "Rocknest," producing the five bite-mark pits visible in this image from the rover's left Navigation Camera (Navcam). Each of the pits is about 2 inches (5 centimeters) wide. The fifth scoopful at Rocknest -- leaving the upper middle bite mark -- was collected during the mission's 93rd Martian day, or sol (Nov. 9, 2012). This image was taken later that same sol. A sample from that fifth scoop was analyzed over the next two sols by Curiosity's Sample Analysis at Mars (SAM) suite of instruments inside the rover. A second sample from the same scoopful of material was delivered to SAM for analysis on Sol 96 (Nov. 12). No further scooping of soil samples is planned at Rocknest. The first Rocknest scoop was collected during Sol 61 (Oct. 7). Fine sand and dust from that scoopful and two subsequent ones were used for scrubbing the inside surfaces of chambers in the sample-handling mechanism on the arm. Samples from scoops three, four and five were analyzed by the Chemistry and Mineralogy instrument inside the rover. 

3. Rock 'Burwash' Near Curiosity, Sol 82 This focus-merge image from the Mars Hand Lens Imager (MAHLI) on the arm of NASA's Mars rover Curiosity shows a rock called "Burwash." The rock has a coating of dust on it. The coarser, visible grains are windblown sand. The focus merge combines portions of eight images taken with the camera held in one position while the MAHLI focus mechanism moved for each of the eight exposures to capture features at different distances in focus. The images were taken during the mission's 82nd sol, or Martian day (Oct. 29, 2012).  MAHLI viewed the rock from a distance of about 4.5 inches (11.5 centimeters). The image covers an area about 3 inches by 2.2 inches (7.6 centimeters by 5.7 centimeters). Burwash is located near the rover's left-front wheel where the rover has been stationed while scooping soil at the site called "Rocknest." 

4. Rock 'Et-Then' Near Curiosity, Sol 82 The Mars Hand Lens Imager (MAHLI) on the arm of NASA's Mars rover Curiosity took this image of a rock called "Et-Then" during the mission's 82nd sol, or Martian day (Oct. 29, 2012.) The rock's informal name comes from the name of an island in Great Slave Lake, Northwest Territories, Canada. MAHLI viewed the rock from a distance of about 15.8 inches (40 centimeters). The image covers an area about 9.5 inches by 7 inches (24 centimeters by 18 centimeters). Et-Then is located near the rover's front left wheel, where the rover has been stationed while scooping soil at the site called "Rocknest.“ This is one of three images acquired by MAHLI from slightly different positions so that a three-dimensional information could be used to plan possible future examination of the rock. 

5. Curiosity's First Three Bites Into Martian Ground Three bite marks left in the Martian ground by the scoop on the robotic arm of NASA's Mars rover Curiosity are visible in this image taken by the rover's right Navigation Camera during the mission's 69th Martian day, or sol (Oct. 15, 2012). The third scoopful, collected on that sol, left the bite or pit farthest to the right. Each of the three bites is about 2 inches (5 centimeters) wide. Of the two bites to the left, the lower one is where Curiosity collected its first scoopful of Martian material, on Sol 61 (Oct. 7, 2012). The upper one is the site of the second scooping, on Sol 66 (Oct. 12, 2012). The location for all of these scoops, and two more planned, is a ripple of windblown dust and sand at a location called "Rocknest.“ The bright circular part of the rover near the bottom center of this image is the observation tray, which is 3 inches (7.8 centimeters) in diameter. 

6. First Sample Placed on Curiosity's Observation Tray The robotic arm on NASA's Mars rover Curiosity delivered a sample of Martian soil to the rover's observation tray for the first time during the mission's 70th Martian day, or sol (Oct. 16, 2012). This image taken later that same sol by the rover's left Mast Camera shows how wind or vibration or both affected the sample after delivery, moving much of it off the tray to the left in this view. The sample came from the third scoopful of material collected at the "Rocknest" patch of windblown dust and sand. 

7. Bright Particle in Hole Dug by Scooping of Martian Soil This image shows part of the small pit or bite created when NASA's Mars rover Curiosity collected its second scoop of Martian soil at a sandy patch called "Rocknest." The bright particle near the center of this image, and similar ones elsewhere in the pit, prompted concern because a small, light-toned shred of debris from the spacecraft had been observed previously nearby (PIA16230). However, the mission's science team assessed the bright particles in this scooped pit to be native Martian material rather than spacecraft debris. This image was taken by the Mars Hand Lens Imager (MAHLI) camera on Curiosity's arm during the 69th Martian day, or sol, of the mission (Oct. 15, 2012), about a week after the scoop dug this hole. The view here covers an area of ground about 1.6 inches (4 centimeters) across. 

8. Bright Particle of Martian Origin in Scoop Hole This image contributed to an interpretation by NASA's Mars rover Curiosity science team that some of the bright particles on the ground near the rover are native Martian material. Other light-toned material nearby (see PIA16230) has been assessed as small debris from the spacecraft. Curiosity's Mars Hand Lens Imager (MAHLI) camera took this image on the mission's 66th Martian day, or sol, (Oct. 12, 2012) showing part of the hole or bite left in the ground when Curiosity collected its first scoop of Martian soil five sols earlier. A clod of soil near the top center of the image contains a light-toned particle. The observation that the particle is embedded in the clod led scientists to assess this particle as Martian material, not something from the spacecraft. This assessment prompted the mission to continue scooping in the area, despite observations of a few light-toned particles in the area being scooped. The image shows an area about 2 inches (5 centimeters) across. It is brightened to improve visibility in the shaded area. 

9. Small Debris on the Ground Beside Curiosity This image from the Mars Hand Lens Imager (MAHLI) camera on NASA's Mars rover Curiosity shows a small bright object on the ground beside the rover at the "Rocknest" site. The object is just below the center of this image. It is about half an inch (1.3 centimeters) long. The rover team has assessed this object as debris from the spacecraft, possibly from the events of landing on Mars. The image was taken during the mission's 65th Martian day, or sol (Oct. 11, 2012). 

10. Curiosity's Location During First Scooping This 360-degree scene shows the surroundings of the location where NASA Mars rover Curiosity arrived on the 59th Martian day, or sol, of the rover's mission on Mars (Oct. 5, 2012). It is a mosaic of images taken by Curiosity's Navigation Camera (Navcam) on sols 59 and 60. Smooth surfaces of the windblown sand and dust of the "Rocknest" area, in the foreground, are what signaled from a distance that this might be an appropriate place to spend about three weeks collecting and using the mission's first few scoopfuls of soil. The rover scooped up its first sample on Sol 61 (Oct. 7, 2012). South is at the center of this panorama, north at both ends. Mount Sharp is on the horizon in the southeast. The "Glenelg" area planned as the next destination lies to the east. Tracks that Curiosity's wheels made while driving toward Rocknest recede toward the west. For scale, Curiosity leaves parallel tracks about 9 feet (2.7 meters) apart. The scene is presented here as a cylindrical projection. 

11. Target: Jake Matijevic Rock This image shows where NASA's Curiosity rover aimed two different instruments to study a rock known as "Jake Matijevic." The red dots are where the Chemistry and Camera (ChemCam) instrument zapped it with its laser on Sept. 21, 2012, and Sept. 24, 2012, which were the 45th and 48th sol, or Martian day of operations. The circular black and white images were taken by ChemCam to look for the pits produced by the laser. The purple circles indicate where the Alpha Particle X-ray Spectrometer trained its view. This image was obtained by Curiosity's Mast Camera on Sept. 21, 2012 PDT (Sept. 22 UTC), or sol 46. An unannotated version of this image is also available. Scientists white-balanced the color in this view to increase the inherent differences visible within the rock. 

12. High-Resolution View of Cross-Section Through a Mars Ripple This image shows the wall of a scuffmark NASA's Curiosity made in a windblown ripple of Martian sand with its wheel. The upper half of the image shows a small portion of the side wall of the scuff and a little bit of the floor of the scuff (bottom of this image). The prominent depression with raised rims at the bottom center of the image was formed by one of the treads on Curiosity's front right wheel. The largest grains in this image are about 0.04 to 0.08 inches (1 to 2 millimeters) in size. Those large grains were on top of the windblown ripple and fell down to this location when the scuff was made. The bulk of the sand in the ripple is smaller, in the range below 0.002 to 0.008 inches (50 to 200 microns). The full scuffmark is 20 inches (50 centimeters) wide, which is the width of Curiosity's wheel. This image from the Mars Hand Lens Imager (MAHLI) is the product of merging eight images acquired at eight slightly different focus settings to bring out details on the wall, slopes, and floor of the wheel scuff. The merge was performed onboard the MAHLI instrument to reduce downlinked data volume. The image was acquired by MAHLI with the lens about 4.7 inches (12 centimeters) from the target. The pixel scale is about 0.002 inches (50 microns) per pixel. The image covers an area, roughly 3 by 2 inches (8 by 6 centimeters). The image was obtained on Oct. 4, 2012, or sol 58, the 58th Martian day of operations on the surface. 

13. Too Big for the Sieve In this image, the scoop on NASA's Curiosity rover shows the larger soil particles that were too big to filter through a sample-processing sieve that is porous only to particles less than 0.006 inches (150 microns) across. After a full-scoop sample had been vibrated over the sieve, this held-back portion was returned to the scoop to be accessible for inspection by the rover's Mast Camera. The image is part of the first "decontamination" exercise by the Collection and Handling forIn-Situ Martian Rock Analysis (CHIMRA) tool on the end of the rover's arm, which includes the scoop, the sieve and other components. The decontamination exercise involved scooping some soil, shaking it thoroughly inside the sample-processing chambers to scrub the internal surfaces, putting it through a sieve, dividing it into the appropriate portions and then discarding the sample. This process will be repeated three times. The rinse-and-discard cycles serve a quality-assurance purpose similar to a common practice in geochemical laboratory analysis on Earth. This image was taken by Curiosity's right Mast Camera (Mastcam-100) on Oct. 10, 2012, the 64th sol, or Martian day, of operations. Scientists white-balanced the color in this view to show the Martian scene as it would appear under the lighting conditions we have on Earth. 

14. Sand Filtered through Curiosity's Sieve This image shows fine sand from Mars that was filtered by NASA's Curiosity rover as part of its first "decontamination" exercise. These particles passed through a sample-processing sieve that is porous only to particles less than 0.006 inches (150 microns) across. The view from the rover's Mast Camera looks into the portion box and "throat" of the Collection and Handling for In-Situ Martian Rock Analysis (CHIMRA) tool on the end of the rover's arm. The decontamination exercise involved scooping some soil, shaking it thoroughly inside the sample-processing chambers to scrub the internal surfaces, putting it through a sieve, dividing it into the appropriate portions, then discarding the sample. This image is downstream of the sieve. The portion box will meter out a portion about the volume of half a baby aspirin so that the instruments receiving the sample will not choke on a sample that is too big. The decontamination procedure will be repeated three times. The rinse-and-discard cycles serve a quality-assurance purpose similar to a common practice in geochemical laboratory analysis on Earth. This image was taken by Curiosity's right Mast Camera (Mastcam-100) on Oct. 10, 2012, the 64th sol, or Martian day, of operations. Scientists white-balanced the color in this view to show the Martian scene as it would appear under the lighting conditions we have on Earth. 

15. Thanks for the Scrub This image from Curiosity's Mast Camera shows NASA's Curiosity rover just after discarding a soil sample as part of its first "decontamination" exercise. A small amount of remnant material is visible inside the delivery tube, which is magnified in the blow-up at lower right. The Collection and Handling for In-Situ Martian Rock Analysis (CHIMRA) tool on the end of the rover's arm had just finished shaking some scooped-up soil thoroughly inside the sample-processing chambers to scrub the internal surfaces, putting it through a sieve and dividing it into the appropriate portions. When the decontamination process has been performed three times and actual sample distribution is ready to occur, the samples will be delivered to the Chemistry and Mineralogy and the Sample Analysis at Mars instruments. The amount being discarded here was about the volume of half a baby aspirin. The rinse-and-discard cycles serve a quality-assurance purpose similar to a common practice in geochemical laboratory analysis on Earth. This image was taken by Curiosity's right Mast Camera (Mastcam-100) on Oct. 10, 2012, the 64th sol, or Martian day, of operations. Scientists white-balanced the color in this view to show the Martian scene as it would appear under the lighting conditions we have on Earth. 

16. Curiosity's Travels Through Sol 56 This map shows the route driven by NASA's Mars rover Curiosity through the 56th Martian day, or sol, of the rover's mission on Mars (Oct. 2, 2012). The route starts where the rover touched down, a site subsequently named Bradbury Landing. The white line extending toward the right (eastward) from Bradbury Landing is the rover's path so far, and the green line shows its planned future route. Numbering of the dots along the line indicate the sol number of each drive. North is up. The scale bar is 200 meters (656 feet). By Sol 56, Curiosity had driven at total distance of about 1,590 feet (484 meters). The Glenelg area farther east is the mission's first major science destination, selected as likely to offer a good target for Curiosity's first analysis of powder collected by drilling into a rock. The image used for the map is from an observation of the landing site by the High Resolution Imaging Science Experiment (HiRISE) instrument on NASA's Mars Reconnaissance Orbiter. 

17. 'Rocknest' From Sol 52 Location This patch of windblown sand and dust downhill from a cluster of dark rocks is the "Rocknest" site, which has been selected as the likely location for first use of the scoop on the arm of NASA's Mars rover Curiosity. This view is a mosaic of images taken by the telephoto right-eye camera of the Mast Camera (Mastcam) during the 52nd Martian day, or sol, of the mission (Sept. 28, 2012), four sols before the rover arrived at Rocknest. The Rocknest patch is about 8 feet by 16 feet (1.5 meters by 5 meters). Scientists white-balanced the color in this view to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain. 

18. Wheel Scuff Mark at 'Rocknest' NASA's Mars rover Curiosity cut a wheel scuff mark into a wind-formed ripple at the "Rocknest" site to give researchers a better opportunity to examine the particle-size distribution of the material forming the ripple. The rover's right Navigation camera took this image of the scuff mark on the mission's 57th Martian day, or sol (Oct. 3, 2012), the same sol that a wheel created the mark. For scale, the width of the wheel track is about 16 inches (40 centimeters). 

19. 'Bathurst Inlet' Rock on Curiosity's Sol 54, Context View NASA's Mars rover Curiosity held its Mars Hand Lens Imager (MAHLI) camera about 10.5 inches (27 centimeters) away from the top of a rock called "Bathurst Inlet" for a set of eight images combined into this merged-focus view of the rock. This context image covers an area roughly 6.5 inches by 5 inches (16 centimeters by 12 centimeters). Resolution is about 105 microns per pixel. MAHLI took the component images for this merged-focus view, plus closer-up images of Bathurst Inlet, during Curiosity's 54th Martian day, or sol (Sept. 30, 2012). The instrument's principal investigator had invited Curiosity's science team to "MAHLI it up!" in the selection of Sol 54 targets for inspection with MAHLI and with the other instrument at the end of Curiosity's arm, the Alpha Particle X-Ray Spectrometer. A merged-focus MAHLI view from closer to the rock, providing even finer resolution, is at PIA14763 . The Bathurst Inlet rock is dark gray and appears to be so fine-grained that MAHLI cannot resolve grains or crystals in it. This means that the grains or crystals, if there are any at all, are smaller than about 80 microns in size. Some windblown sand-sized grains or dust aggregates have accumulated on the surface of the rock but this surface is clean compared to, for example, the pebbly substrate below the rock (upper left and lower right in this context image). MAHLI can do focus merging onboard. The full-frame versions of the eight separate images that were combined into this view were not even returned to Earth -- just the thumbnail versions. Merging the images onboard reduces the volume of data that needs to be downlinked to Earth. 

20. Remnants of Ancient Streambed on Mars NASA's Curiosity rover found evidence for an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here, which the science team has named "Hottah" after Hottah Lake in Canada’s Northwest Territories. It may look like a broken sidewalk, but this geological feature on Mars is actually exposed bedrock made up of smaller fragments cemented together, or what geologists call a sedimentary conglomerate. Scientists theorize that the bedrock was disrupted in the past, giving it the titled angle, most likely via impacts from meteorites. The key evidence for the ancient stream comes from the size and rounded shape of the gravel in and around the bedrock. Hottah has pieces of gravel embedded in it, called clasts, up to a couple inches (few centimeters) in size and located within a matrix of sand-sized material. Some of the clasts are round in shape, leading the science team to conclude they were transported by a vigorous flow of water. The grains are too large to have been moved by wind. A close-up view of Hottah reveals more details of the outcrop. Broken surfaces of the outcrop have rounded, gravel clasts, such as the one circled in white, which is about 1.2 inches (3 centimeters) across. Erosion of the outcrop results in gravel clasts that protrude from the outcrop and ultimately fall onto the ground, creating the gravel pile at left.  This image mosaic was taken by Curiosity's 100-millimeter Mastcam telephoto lens on its 39th Martian day, or sol, of the mission (Sept. 14, 2012 PDT/Sept. 15 GMT). 

21. Best View of Goulburn Scour This image from NASA's Curiosity Rover shows a high-resolution view of an area that is known as Goulburn Scour, a set of rocks blasted by the engines of Curiosity's descent stage on Mars. It shows a section from a mosaic of a pair of images obtained by Curiosity's 100-millimeter Mast Camera, with three times higher resolution than previously released. Details of the layer of pebbles can be seen in the close-up. These two images were the first views of this sandy conglomerate, a sedimentary layer laid down by water in the very distant past and uncovered in August 2012 during the rover's landing. The inset magnifies the area by a factor of two. Mastcam obtained these images on Aug. 19, 2012, or the 13th sol, or Martian day, of Curiosity's surface operations. 

22. Link to a Watery Past In this image from NASA's Curiosity rover, a rock outcrop called Link pops out from a Martian surface that is elsewhere blanketed by reddish-brown dust. The fractured Link outcrop has blocks of exposed, clean surfaces. Rounded gravel fragments, or clasts, up to a couple inches (few centimeters) in size are in a matrix of white material. Many gravel-sized rocks have eroded out of the outcrop onto the surface, particularly in the left portion of the frame. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Water transport is the only process capable of producing the rounded shape of clasts of this size. The Link outcrop was imaged with the 100-millimeter Mast Camera on Sept. 2, 2012, which was the 27th sol, or Martian day of operations. The name Link is derived from a significant rock formation in the Northwest Territories of Canada, where there is also a lake with the same name. Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain. 

23. Rock Outcrops on Mars and Earth This set of images compares the Link outcrop of rocks on Mars (left) with similar rocks seen on Earth (right). The image of Link, obtained by NASA's Curiosity rover, shows rounded gravel fragments, or clasts, up to a couple inches (few centimeters), within the rock outcrop. Erosion of the outcrop results in gravel clasts that fall onto the ground, creating the gravel pile at left. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. A typical Earth example of sedimentary conglomerate formed of gravel fragments in a stream is shown on the right. An annotated version of the image highlights a piece of gravel that is about 0.4 inches (1 centimeter) across. It was selected as an example of coarse size and rounded shape. Rounded grains (of any size) occur by abrasion in sediment transport, by wind or water, when the grains bounce against each other. Gravel fragments are too large to be transported by wind. At this size, scientists know the rounding occurred in water transport in a stream. The name Link is derived from a significant rock formation in the Northwest Territories of Canada, where there is also a lake with the same name. Scientists enhanced the color in the Mars image to show the scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain. The Link outcrop was imaged with the 100-millimeter Mast Camera on Sept. 2, 2012, which was the 27th sol, or Martian day of operations. 

24. Curiosity's Rock-Contact Science Begins This image shows the robotic arm of NASA's Mars rover Curiosity with the first rock touched by an instrument on the arm. The rover's right Navigation Camera (Navcam) took this image during the 46th Martian day, or sol, of the mission (Sept. 22, 2012). On that sol, the rover placed the Alpha Particle X-Ray Spectrometer (APXS) instrument onto the rock to assess what chemical elements were present in the rock. The rock is named "Jake Matijevic" in commemoration of influential Mars-rover engineer Jacob Matijevic (1947-2012). 

25. Portrait of APXS on Mars This image shows the Alpha Particle X-Ray Spectrometer (APXS) on NASA's Curiosity rover, with the Martian landscape in the background. The image was taken by Curiosity's Mast Camera on the 32nd Martian day, or sol, of operations on the surface (Sept. 7, 2012, PDT or Sept. 8, 2012, UTC). APXS can be seen in the middle of the picture. This image let researchers know that the APXS instrument had not become caked with dust during Curiosity's dusty landing. Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain. 

26. Hello, MAHLI This image shows the Mars Hand Lens Imager (MAHLI) on NASA's Curiosity rover, with the Martian landscape in the background. The image was taken by Curiosity's Mast Camera on the 32nd Martian day, or sol, of operations on the surface (Sept. 7, 2012, PDT or Sept. 8, 2012, UTC). MAHLI, with its LED (light-emitting diode) lights on, can be seen in the middle of the picture. Scientists and engineers imaged MAHLI to inspect its dust cover and check that its LED lights are functional. Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain. 

27. BrigWheels and a Destination This view of the three left wheels of NASA's Mars rover Curiosity combines two images that were taken by the rover's Mars Hand Lens Imager (MAHLI) during the 34th Martian day, or sol, of Curiosity's work on Mars (Sept. 9, 2012). In the distance is the lower slope of Mount Sharp. The camera is located in the turret of tools at the end of Curiosity's robotic arm. The Sol 34 imaging by MAHLI was part of a week-long set of activities for characterizing the movement of the arm in Mars conditions. The main purpose of Curiosity's MAHLI camera is to acquire close-up, high-resolution views of rocks and soil at the rover's Gale Crater field site. The camera is capable of focusing on any target at distances of about 0.8 inch (2.1 centimeters) to infinity, providing versatility for other uses, such as views of the rover itself from different angles. Image Credit: NASA/JPL-Caltech/Malin Space Science Systemsht Particle in Hole Dug by Scooping of Martian Soil This image shows part of the small pit or bite created when NASA's Mars rover Curiosity collected its second scoop of Martian soil at a sandy patch called "Rocknest." The bright particle near the center of this image, and similar ones elsewhere in the pit, prompted concern because a small, light-toned shred of debris from the spacecraft had been observed previously nearby (PIA16230). However, the mission's science team assessed the bright particles in this scooped pit to be native Martian material rather than spacecraft debris. This image was taken by the Mars Hand Lens Imager (MAHLI) camera on Curiosity's arm during the 69th Martian day, or sol, of the mission (Oct. 15, 2012), about a week after the scoop dug this hole. The view here covers an area of ground about 1.6 inches (4 centimeters) across.
