PIA05220: Back in Action

This image shows the Mars Exploration Rover Spirit's "hand," or the tip of the instrument deployment device, poised in front of the rock nicknamed Adirondack, the rover's first science target since developing communication problems over two weeks ago. In preparation for grinding into Adirondack, Spirit cleaned off a portion of the rock's surface with a stainless steel brush located on its rock abrasion tool and seen here at the end of the yellow arrow. The image was taken by the rover's panoramic camera.

PIA05283: Flaky "Mimi"

This color image taken by the Mars Exploration Rover Spirit's panoramic camera on Sol 40 is centered on an unusually flaky rock called Mimi. Mimi is only one of many features in the area known as "Stone Council," but looks very different from any rock that scientists have seen at the Gusev crater site so far. Mimi's flaky appearance leads scientists to a number of hypotheses. Mimi could have been subjected to pressure either through burial or impact, or may have once been a dune that was cemented into flaky layers, a process that sometimes involves the action of water.

“勇气”号拍摄的岩石与众不同

　　星期天是勇气号在火星上的第42天，它利用其机械臂勘查了一块与众不同的岩石，科学家把这块石头昵称为“米米”。

　　“米米”之所以引起科学家的极大兴趣是由于它具有与众不同的薄片形状，与周围环境中其他石头的形状极为不同，科学家正试图通过机遇号所拍摄的“米米”显微图片及其光谱解开它与众不同的谜团。机遇号使命负责人吉姆埃里克森认为，岩石呈薄片形状，说明该岩石不是由于火山爆发突然形成的，往往是经过很长时期才能形成的层积岩。因此，“米米”身上很可能蕴藏丰富的火星地质历史线索。

　　对“米米”的探索仅仅是勇气号短暂的一站，其后它将长途跋涉，去创造它在火星上的行走记录。按照计划，星期一上午勇气号将行进25米，稍事休整后，下午再行进25米，该记录也将成为人类机器人一天在火星上行走的最远记录。而此前，勇气号在火星上的行走记录是一天行进24米。“勇气”号的目的地将是“博纳维尔坑”，距其着陆点约240米，估计“勇气”号将需要18天才能抵达。

　　“大病初愈”的勇气号目前“健康”状态良好，表现极佳。美国航空航天局目前又对其数据传输系统进行了升级，使数据传输速率提高了近一倍，相信勇气号今后还会有更佳的表现。

　　与此同时，“机遇”号还在从事着挖沟的苦工，以期在挖出的土壤中找到证明火星有水的赤铁矿。图中较大块岩石为“米米”。(何屹)

PIA05290: Sailing to White Boat

This is a composite red-green-blue image of the rock called White Boat. It is the first rock target that Spirit drove to after finishing a series of investigations on the rock Adirondack. White Boat stood out to scientists due to its light color and more tabular shape compared to the dark, rounded rocks that surround it.

PIA05330: 'Laguna Hollow' Undisturbed

这是勇气号发回的合成彩色照片。照片显示了火星土壤中的小颗粒排成纹路。

This image shows the patch of soil at the bottom of the shallow depression dubbed "Laguna Hollow" where the Mars Exploration Rover Spirit will soon begin trenching. Scientists are intrigued by the clustering of small pebbles and the crack-like fine lines, which indicate a coherent surface that expands and contracts. A number of processes can cause materials to expand and contract, including cycles of heating and cooling; freezing and thawing; and rising and falling of salty liquids within a substance. This false-color image was created using the blue, green and infrared filters of the rover's panoramic camera. Scientists chose this particular combination of filters to enhance the heterogeneity of the martian soil.

Ripples or Dunes

涟漪或者沙丘

This approximate true-color image taken by the Mars Exploration Rover Spirit's panoramic camera shows the windblown waves of soil that characterize the rocky surface of Gusev Crater, Mars. Scientists were puzzled about whether these geologic features were "ripples" or "dunes." Ripples are shaped by gentle winds that deposit coarse grains on the tops or crests of the waves. Dunes are carved by faster winds and contain a more uniform distribution of material. Images taken of these features by the rover's microscopic imager on the 41st martian sol, or day, of the rover's mission revealed their identity to be ripples. This information helps scientists better understand the winds that shape the landscape of Mars. This image was taken early in Spirit's mission.

PIA05453: Are They Telltale Ripples?

This false-color image from the Mars Exploration Rover Spirit's panoramic camera shows peak-like formations on the martian terrain at Gusev Crater. Scientists have been analyzing these formations, which have coarse particles accumulating on their tops, or crests. This characteristic classifies them as ripples instead of dunes, which have a more uniform distribution of particle sizes. Scientists are looking further into such formations, which can give insight to the wind direction and velocity on Mars, as well as the material that is being moved by the wind. This image was taken on the 40th martian day, or sol, of Spirit's mission.

PIA05501: A Hole In HumphreyThis false-color image taken by the panoramic camera on the Mars Exploration Rover Spirit shows the rock dubbed "Humphrey" and the hole drilled into the rock by the rover. Spirit ground into the rock with the rock abrasion tool located on its robotic arm on the 60th martian day, or sol, of its mission. Scientists are investigating the freshly exposed rock with the scientific instruments on the arm. Spirit is about halfway to a large crater nicknamed "Bonneville." This image was made by combining data from the camera's different wavelength filters. The particular filters used were chosen to enhance features of scientific interest.

PIA05570: "Bonneville in Color".

The rim and interior of a crater nicknamed "Bonneville" dominate this 180-degree, false-color mosaic of images taken by the panoramic camera of NASA's Mars Exploration Rover Spirit. Spirit recorded this view on the rover's 68th sol, March 12, 2004, one sol after reaching this location. The rover remaining here in part to get this very high-resolution, color mosaic, from which scientists can gain insight about the depth of the surface material at Bonneville and make future observation plans. On sol 71, Spirit was instructed to drive approximately 15 meters (49 feet) along the crater rim to a new vantage point.

PIA05574: The Road to 'Bonneville'

This false-color panoramic camera composite traverse map depicts the Mars Exploration Rover Spirit's journey since landing at Gusev Crater, Mars. It was generated from three of the camera's different wavelength filters (750 nanometers, 530 nanometers and 480 nanometers). This map was created on the 65th martian day, or sol, of Spirit's mission, after Spirit had traveled 328 meters (1076 feet) from its lander to the rim of the crater dubbed "Bonneville." From this high point, Spirit was able to capture with its panoramic camera the entire rover traverse. The map points out major stops that Spirit made along the way, including features nicknamed "Adirondack;" "Stone Council;" "Laguna Hollow;" and "Humphrey." Also highlighted is the landscape feature informally named "Grissom Hill" and Spirit's landing site, the Columbia Memorial Station.

PIA05592: 'Serpent' Scuff

This mosaic image from the Mars Exploration Rover Spirit panoramic camera shows the trench or "scuff" mark in the Gusev Crater location dubbed "Serpent." The trench is approximately 30-35 centimeters (12-14 inches) across and 40-45 centimeters (16-18 inches) long from top to bottom. Work using the rover's instrument deployment device, or"arm," was completed on the undisturbed surface of the drift as well as within the interior of the trench. This image is in approximate true color, based on a scaling of data from the red, green and blue (750 nanometers, 530 nanometers, and 430 nanometers) filters.

PIA05593: Spirit's Destination


This image, cropped from a larger panoramic image mosaic taken by the Mars Exploration Rover Spirit panoramic camera, shows the rover's destination toward the hills nicknamed the "Columbia Hills." The rover is currently positioned outside the view of this image, on the right. This image was taken on sols 68 and 69 of Spirit's mission (March 12 and 13, 2004) from the location the rover first reached on the western rim of the crater. The image is in approximate true color, based on a scaling of data from the red, green and blue (750 nanometers, 530 nanometers, and 480 nanometers) filters.

PIA05679: 'Mazatzal's' Sparkly Self

This enhanced-color image taken by the microscopic imager on the Mars Exploration Rover Spirit on sol 79 shows the rock dubbed "Mazatzal" after a portion of its surface was brushed clean by the rover's rock abrasion tool. The reddish material on the right side of the image is the original dust coating. The darker, grayer surface on the left side was exposed after brushing. The crack in the rock may have once contained fluids from which minerals precipitated along its walls. The color in this image was created by combining pictures taken with the microscopic imager's orange-tinted dust cover in both its open and closed positions.

PIA05681: 'Mazatzal' Before the Grind

This approximate true-color image taken by the panoramic camera on the Mars Exploration Rover Spirit shows the rock dubbed "Mazatzal" before the rover drilled into it with its rock abrasion tool. On sol 82, Spirit ground into a circular patch of the rock called "New York," then repeated this operation on sol 85 to complete the hole. Several observations were made during this grinding process with the rover's suite of scientific instruments. Preliminary results suggest that fluid may have been present during Mazatzal's formation. Images from the panoramic camera's blue, green and red filters (480, 530 and 600-nanometer filters) were combined to make this picture.
