PIA05725: Heading for the Hills

This enhanced false-color mosaic image from the Mars Exploration Rover Spirit panoramic camera shows the view acquired after the rover drove approximately 50.2 meters (165 feet) on the martian afternoon of sol 89 (April 3, 2004). The view shows the direction of the rover's future drive destination. In the distance are the eastern-lying "Columbia Hills." This image was assembled from images in the panoramic camera's near-infrared (750 nanometer), green (530 nanometer), and violet (432 nanometer) filters. The colors have been exaggerated to enhance the differences between cleaner and dustier rocks, and lighter and darker soils.

'Bonneville Crater' Panorama
'博纳维尔火山口' 的360度全景酷图！
May 18, 2004

This 360-degree view from a position beside the crater informally named "Bonneville" was assembled from frames taken by the panoramic camera on NASA's Mars Exploration Rover Spirit. Half of this panorama was first released on March 15, 2004. The entire mosaic, recently completed, reveals not only the crater rim and interior, but Spirit's tracks and a glimpse at part of the rover. The images were acquired on sol 68, March 12, 2004, just one day after Spirit reached this location. The image is a false-color composite made from frames taken with the camera's L2 (750 nanometer), L5 (530 nanometer) and L6 (480 nanometer) filters.

PIA06006: The 'Columbia Hills' in Color

NASA's Mars Exploration Rover Spirit used its panoramic camera to take the images that make up this full-resolution mosaic of the "Columbia Hills." Spirit acquired these images on sol 131 (May 16, 2004), when it sat less than one kilometer (0.62 miles) away from its target, the base of the hills. Spirit will reach the base before sol 160 and begin an in-depth exploration of the interesting geologic features that make up these hills.

The image is approximately 5,300 pixels wide by 400 pixels high and was assembled from six adjacent sets of panoramic camera images. It is an approximate true-color rendering made from the camera's 750-, 530- and 480- nanometer filters. A small amount of image filtering was applied to bring out some of the subtle, geologic details found in the hills.

PIA06045: Approaching the Hills

This approximate true-color rendering of the central part of the "Columbia Hills" was made using images taken by NASA's Mars Exploration Rover Spirit panoramic camera. Scientists plan to use the science instruments on the rover to analyze the composition of rock and soil at the hills," Spirit's planned destination. The images in this mosaic, acquired on sol 149 (June 3, 2004), were taken with the camera's 600, 530, and 480 nanometer filters from three rover positions approximately 300 meters (984 feet) away from the base of the hills.

PIA06271: 'Pot of Gold'

This false-color image taken by the panoramic camera on the Mars Exploration Rover Spirit shows the rock dubbed "ot of Gold" (upper left), located near the base of the "Columbia Hills" in Gusev Crater. The rock's nodules and layered appearance have inspired rover team members to investigate the rock's detailed chemistry in coming sols. This picture was taken on sol 158 (June 13, 2004).

PIA06272: 'Pot of Gold' Close-up

This false-color image taken by the panoramic camera on the Mars Exploration Rover Spirit shows a close-up of the rock dubbed "ot of Gold" (left), which is located near the base of the "Columbia Hills" in Gusev Crater. Scientists are intrigued by this unusual-looking, nodule-covered rock and plan to investigate its detailed chemistry in coming sols. This picture was taken on sol 159 (June 14, 2004).

PIA06273: Dirty Rotten Rocks

This false-color image taken by the panoramic camera on the Mars Exploration Rover Spirit shows a collection of rocks (upper right) at Gusev Crater that have captured the attention of scientists for their resemblance to rotting loaves of bread. The insides of the rocks appear to have been eroded, while their outer rinds remain more intact. These outer rinds are reminiscent of those found on rocks at Meridiani Planum's "Eagle Crater." This image was captured on sol 158 (June 13, 2004).

PIA06278: 'Pot of Gold' and 'Rotten Rocks'

This false-color image taken by the panoramic camera on the Mars Exploration Rover Spirit shows the rock dubbed "ot of Gold" (upper left), located near the base of the "Columbia Hills" in Gusev Crater. Scientists are intrigued by this unusual-looking, nodule-covered rock and plan to investigate its detailed chemistry in coming sols. This picture was taken on sol 159 (June 14, 2004).

To the right is a set of rocks referred to as "Rotten Rocks" for their resemblance to rotting loaves of bread. The insides of these rocks appear to have been eroded, while their outer rinds remain more intact. These outer rinds are reminiscent of those found on rocks at Meridiani Planum's "Eagle Crater." This image was captured on sol 158 (June 13, 2004).

'Hank's Hollow' Sparkles

This false-color composite panoramic camera image highlights mysterious and sparkly dust-like material that is created when the soil in this region is disturbed. NASA's Mars Exploration Rover Spirit took this image on sol 165 (June 20, 2004) in "Hank's Hollow," using filters L2, L5 and L7.

美国宇航局喷气推进实验室的科学家１６号公布了一组“勇气”号火星车传回的新照片，戈隆贝克博士当天还向新闻界公布了一张“勇气”号向地面传回的火星表层全景照片，这是第四张美国宇航局从火星获得的全景照片，戈隆贝克博士认为它对所有美国宇航局的科学家和工程师们而言都是一份珍贵的战利品。

　　'Santa Anita' Panorama
7/16/04
This color mosaic taken on May 21, 25 and 26, 2004, by the panoramic camera on NASA's Mars Exploration Rover Spirit was acquired from a position roughly three-fourths the way between "Bonneville Crater" and the base of the "Columbia Hills." The area is within a low thermal inertia unit (an area that heats up and cools off quickly) identified from orbit by the Mars Odyssey thermal emission imaging system instrument. The rover was roughly 600 meters (1,968 feet) from the base of the hills.
This mosaic, referred to as the "Santa Anita Panorama," is comprised of 64 pointings, acquired with six of the panoramic camera's color filters, including one designed specifically to allow comparisons between orbital and surface brightness data. A total of 384 images were acquired as part of this panorama. The mosaic is an approximate true-color rendering constructed from images using the camera's 750-, 530- and and 480-nanometer filters, and is presented at the full resolution of the camera.

The Call of the Dark Rocks (true-color)
8/18/04
This approximate true-color rendering from NASA's Mars Exploration Rover Spirit shows a set of darker rocks dubbed "Toltecs" lying southeast of the rover's current position. These rocks are believed to be basaltic, or volcanic, in composition, because their spectral properties match those of other basaltic rocks studied in Gusev Crater. Scientists hope to use these presumably unaltered rocks as a geologic standard for comparison to altered rocks in the area, such as "Clovis." This image was taken with the panoramic camera's 600-, 530-, and 480-nanometer filters on sol 220 (Aug. 15, 2004).

彩色的'克洛维斯' 岩石。

'Clovis' in Color
8/18/04
This approximate true-color image taken by the Mars Exploration Rover Spirit shows the rock outcrop dubbed "Clovis." The rock was discovered to be softer than other rocks studied so far at Gusev Crater after the rover easily ground a hole into it with its rock abrasion tool. An analysis of the interior of the hole with the rover's scientific instruments found higher concentrations of sulfur, bromine and chlorine compared to basaltic, or volcanic, rocks at Gusev. This might indicate that Clovis was chemically altered, and that fluids once flowed through the rock depositing these elements. This image was taken by the 750-, 530- and 480-nanometer filters of the rover's panoramic camera on sol 217(August 13, 2004).

　美国宇航局的火星车勇气号自6月开始攀登哥伦比亚山，在一个轮子受损、电量不足的情况下继续艰难跋涉，不过也因此得以忙里偷闲观赏一下火星的全景。日前勇气号从攀登哥伦比亚山的半路上传回了火星的全景图片；机遇号也在欧洲航天局卫星的帮助下传回了最新的火星图片。

　　上周勇气号艰难地爬上了山脉一侧一个突出的、名为“西马刺”的山顶后，得以俯瞰火星全景。火星车不能以超过20度的倾斜角前进，所以采取“之”字形路线从马刺的一侧攀登而上，现在它正勘测这个地方的地质概况。


　　自从在古谢夫弹坑(Gusev Crater)弹坑着陆，勇气号已经行走了超过3千米的路程，运行了218个火星日(火星日比地球日稍微长一点)。这已经远远超过了它90个火星日的预计任务时限，现在正显示出衰老的迹象。“但是它每项工作都干得非常出色，”宇航局推进技术实验室勇气号工程师之一杰克-马蒂杰维克说。

　　大约一个月前，由于一个变速箱出错，火星车的右前轮大量消耗原本已快耗尽的电池能量。所以工程师现在控制它向后行使，为受伤的轮子减轻压力并保存能量。

　　火星冬天渐渐临近，白天太阳能电池板吸收的太阳光较少，所以火星车每天只能工作一到两个小时。9月10日，火星和地球将处在太阳相反的位置上，和勇气号的通讯将中断。火星冬至也在将在这个时候到来。因此，马蒂杰维克说，他们可能要让火星车冬眠一星期，让它的太阳能电池板对准衰弱的太阳光，储存能量。“我一直认为火星车有着惊人的潜力。”他说。



　　马蒂杰维克希望勇气号冬眠之前能够到达哥伦比亚山顶，可以更好的观赏周围地区壮观的景色。然后勇气号将从另一面下山，查看山后的情况。轨道测量法显示远处的平原有着不同的岩石结构，将为这位逐渐变老的机器地理学家提供丰富的样本。

　　在火星的另一侧，勇气号的兄弟机遇号仍然在勘测耐力坑(Endurance Crater)，那是本初子午线平面(Meridiani Planum)地区一个直径130米的弹坑。最近，机遇号在欧洲航天局卫星的帮助下，向地球传送图片，这是该卫星第一次为火星车提供通讯联系。(梦飞/编译）

火星车发现“奇境” 找到更多曾有水的证据

　据报道，当地时间8月18日(北京时间8月19日)美国宇航局的科学家表示，在火星登陆的两个探测器发现了一块拥有怪石和迷人沙丘的“奇境”，同时找到更多的火星上曾经有水的证据。

　　勇气号和机遇号曾在2004年3月发现了很久以前火星上有水的迹象。目前，勇气号在它着陆的古塞夫坑前进了近2英里，进入一个被命名为“哥伦比亚”的山地。喷气推进实验室的科学家表示，在距离古塞夫坑地面大约30英尺高的一座山丘上，勇气号最近在这里发现了曾经有水的迹象，这些水改变了被命名为“克洛维斯”岩床上裸露的岩石。这些岩石里的硫磺、氯和溴含量要平原上的岩石多得多。

　　科学小组成员杜格·明格解释说，这些物质一般是火山喷发出来的，可能已经与液态水或水蒸气发生化合反应。负责这次火星探测任务的首席科学家斯奎尔斯表示：“我们在这里发现了一些更大更深的变化，这意味着这里曾有过更多的水。”

　　与此同时，在火星的另一侧，机遇号前进了32英尺，抵达“忍耐”坑，这是一块和体育馆差不多大小的低地。在坑底，机遇号发现了一些波纹状沙丘和一块怪异的石头。科学家一直没有搞清楚这块岩石是如何形成的。斯奎尔斯说：“我对这块石头的样子无法作出解释，我们以前从未见过这种岩石。”

　　这个研究小组希望机遇号可以勘察一下这些沙丘的边，当然，它不会跑进这些沙丘里边去，主要是担心陷在里面。斯奎尔斯解释说：“我们造的探测车非常好，但我们造的不是沙丘车。”他继续说，在一个层次分明的斜坡上，机遇号发现不同层次的岩石有很大不同，一块被命名为“磨石”的岩石上有一些很小的波纹，这明显是它与流动水长时间接触的标志。(杨孝文/编译）

Perched Above Gusev Crater
8/18/04
This approximate true-color image taken by the Mars Exploration Rover Spirit shows a rock outcrop dubbed "Longhorn," and behind it, the sweeping plains of Gusev Crater. On the horizon, the rim of Gusev Crater is clearly visible. The view is to the south of the rover's current position. The image consists of four frames taken by the 750-, 530- and 430-nanometer filters of Spirit's panoramic camera on sol 210 (August 5, 2004).

Deep Hole in 'Clovis'

8/27/04
At a rock called "Clovis," the rock abrasion tool on NASA抯 Mars Exploration Rover Spirit cut a 9-millimeter (0.35-inch) hole during the rover's 216th martian day, or sol (Aug. 11, 2004). The hole is the deepest drilled in a rock on Mars so far. This approximately true-color view was made from images taken by Spirit's panoramic camera on sol 226 (Aug. 21, 2004) at around 12:50 p.m. local true solar time -- early afternoon in Gusev Crater on Mars. To the right is a "brush flower" of circles produced by scrubbing the surface of the rock with the abrasion tool's wire brush. Scientists used rover's Moessbauer spectrometer and alpha particle X-ray spectrometer to look for iron-bearing minerals and determine the elemental chemical composition of the rock. This composite combines images taken with the camera's 600-, 530- and 480-nanometer filters. The diameter of the hole cut into the rock is 4.5 centimeters (1.8 inches).
