美国航天局的图像是2012年8月29日拍摄的,好吧,也许只有我。但是,较年轻的陨石坑叠加在较老的陨石坑上(在本例中,两个较小的陨石坑位于较老的陨石坑边缘)可能会导致地形看起来更像人眼熟悉的形状。更普遍地说,叠加定律使科学家能够确定哪些地表特征是在其他特征之前和之后出现的,从而更好地了解水星表面不同区域的地质历史。这张图像是作为一个高分辨率的目标观察获得的。目标观测是水星表面一小块区域的图像,分辨率远高于200米/像素的形态学基础图。以这种高分辨率覆盖水星表面是不可能的,但通常每周都会有几个高科学价值的区域以这种方式成像。信使号宇宙飞船是有史以来第一个环绕水星运行的宇宙飞船,宇宙飞船的七个科学仪器和无线电科学研究正在揭开太阳系最内层行星的历史和演变。参观水星的原因?本网站的一节,以了解更多有关信使任务正在解决的关键科学问题。在为期一年的主要任务中,信使号获得了88746幅图像和大量其他数据集。“信使”号目前正在进行为期一年的延期任务,在这一任务中,计划需要获得超过8万张额外的图像,以支持“信使”号的科学目标。点击此处阅读更多关于信使任务的信息:www.nasa.gov/mission-pages/MESSENGER/main/index.html学分:nasa/Johns Hopkins University Applied Physics Laboratory/Carnegie institute of Washington美国宇航局图像使用政策。美国宇航局goddard航天飞行中心通过四项科学努力实现美国宇航局的使命:地球科学、太阳物理学、太阳系探索和天体物理学。戈达德通过贡献令人信服的科学知识来推进宇航局的任务,在宇航局的成就中发挥了领导作用。关注我们的twitter,就像我们关注我们的twitter一样?ref=tsd“rel=”nofollow“>在Facebook上找到我们吗?vm=grid“rel=”nofollow“>安装程序
Anyone Else Think This Looks Like the Cookie Monster?
NASA image acquired August 29, 2012 Ok, so maybe it's just me. But the superposition of younger craters on older craters (in this case two smaller craters upon the rim of an older crater) can result in landforms that appear to resemble more familiar shapes to human eyes. More generally, the Law of Superposition allows scientists to determine which surface features pre- and postdate others, leading to a better understanding of the geological history of different regions of Mercury's surface. This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week. The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. Visit the Why Mercury? section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MESSENGER acquired 88,746 images and extensive other data sets. MESSENGER is now in a yearlong extended mission, during which plans call for the acquisition of more than 80,000 additional images to support MESSENGER's science goals.

发布日期:2011年12月21日图片中心的陨石坑以1812年至1870年英国小说家查尔斯·狄更斯的名字命名为狄更斯。狄更斯的著名作品包括圣诞颂歌、鲍勃·克拉奇、他的家人和可怕的老板斯克鲁奇的故事。研究水星的科学家们可能认为水手10号任务是圣诞节的过去,信使是圣诞节的礼物,欧洲贝比科伦坡任务是圣诞节的未来。此图像是作为MDIS高分辨率表面形态基础图的一部分获取的。表面形态基础地图将覆盖90%以上的水星表面,平均分辨率为250米/像素(0.16英里/像素或820英尺/像素)。为地表形态基础图采集的图像通常具有偏离垂直太阳角(即高入射角)和可见阴影,以便清楚地显示地质特征的地形形式。信使号宇宙飞船是有史以来第一个环绕水星运行的宇宙飞船,宇宙飞船的七个科学仪器和无线电科学研究正在揭开太阳系最内层行星的历史和演变。参观水星的原因?本网站的一节,以了解更多有关信使任务正在解决的关键科学问题。在为期一年的主要任务中,MDIS计划获取超过75000张图像,以支持信使的科学目标。学分:美国宇航局/约翰霍普金斯大学应用物理实验室/华盛顿卡内基研究所中心通过地球科学、太阳物理学、太阳系探索和天体物理学四项科学努力实现了美国宇航局的使命。戈达德通过贡献令人信服的科学知识来推进宇航局的任务,在宇航局的成就中发挥了领导作用。关注我们的twitter,就像我们关注我们的twitter一样?ref=tsd“rel=”nofollow“>在Facebook上找到我们吗?vm=grid“rel=”nofollow“>安装程序
A Christmas Crater from Mercury
Release Date: December 21, 2011 The crater at the center of this image is named Dickens, after Charles Dickens, the English novelist who lived from 1812 to 1870. Among Dickens' famous works is A Christmas Carol, the story of Bob Cratchit, his family, and horrible boss Mr. Scrooge. Scientists studying Mercury might consider the Mariner 10 mission to be Christmas Past, MESSENGER to be Christmas Present, and the European Bepi-Colombo mission to be Christmas Yet To Come. This image was acquired as part of MDIS's high-resolution surface morphology base map. The surface morphology base map will cover more than 90% of Mercury's surface with an average resolution of 250 meters/pixel (0.16 miles/pixel or 820 feet/pixel). Images acquired for the surface morphology base map typically have off-vertical Sun angles (i.e., high incidence angles) and visible shadows so as to reveal clearly the topographic form of geologic features. The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. Visit the Why Mercury? section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.

佛罗里达州卡纳维拉尔角——在佛罗里达州提图斯维尔的Astrotech太空行动中,技术人员在月球勘测轨道器(简称LRO)与美国宇航局的月球陨石坑观测和传感卫星(简称LCROSS)匹配之前,将保护袋完全放在其周围。这颗卫星的主要任务是在月球两极附近的一个永久阴影坑中寻找月球上的水冰。LCROSS是一种低成本、加速发展的NASA月球侦察轨道器(LRO)的配套任务。LCROSS和LRO是美国宇航局计划中的第一批任务,计划在2020年前将人类送回月球,并开始建立月球前哨基地。发射目标是不早于6月2日从佛罗里达州卡纳维拉尔角空军基地发射。图片来源:NASA/Jack Pfaller

CAPE CANAVERAL, Fla. – At Astrotech Space Operations in Titusville, Fla., technicians complete placing the protective bag around the Lunar Reconnaissance Orbiter, or LRO, before it is mated with NASA's Lunar CRater Observation and Sensing Satellite, known as LCROSS, spacecraft. The satellite's primary mission is to search for water ice on the moon in a permanently shadowed crater near one of the lunar poles. LCROSS is a low-cost, accelerated-development, companion mission to NASA's Lunar Reconnaissance Orbiter, or LRO. LCROSS and LRO are the first missions in NASA's plan to return humans to the moon and begin establishing a lunar outpost by 2020. Launch is targeted for no earlier than June 2 from Cape Canaveral Air Force Station in Florida. Photo credit: NASA/Jack Pfaller
