2022年9月17日 Perseverance in Jezero Crater’s Delta Image Credit: NASA, JPL-Caltech, MSSS, ASU Explanation: The Perseverance rover’s Mastcam-Z captured images to create this mosaic on August 4, 2022. The car-sized robot was continuing its exploration of the fan-shaped delta of a river that, billions of years ago, flowed into Jezero Crater on Mars. S...
NASA的毅力号火星车将其机械臂放置在火星耶泽罗陨石坑中一个名为“斯金纳岭”的岩石露头周围。这幅由多幅图像组成的拼图显示了三角洲悬崖表面的层状沉积岩，以及火星车研磨圆形斑块以分析岩石成分的位置之一。 影像来源：NASA/JPL-Caltech/ASU/MSSS NASA的毅力号火星车正在进行第二次科学活动，在一个长期以来被科学家认为是在火星上寻找古代微生物生命迹象的最有希望的区域内采集岩芯样本。自7月7日以来，火星车从红色星球杰泽罗陨石坑的一个古老河流三角洲采集了四个样本，使具有科学意义的岩石样本总数达到了12个。 “我们之所以选择耶泽罗陨石坑进行探索，是因为我们认为它有最好的机会提供科学上优秀的样本，现在我们知道我们把探测器送到了正确的位置。”NASA华盛顿科学副局长托马斯·祖尔布琴说。“前两次科学活动产生了...
2022年9月4日 Sea and Sky Glows over the Oregon Coast Image Credit & Copyright: Rudy Montoya Explanation: Every step caused the sand to light up blue. That glow was bioluminescence — a blue radiance that also lights the surf in this surreal scene captured in mid-2018 at Meyer’s Creek Beach in Oregon, USA. Volcanic stacks dot the foreground sea, ...

2022年8月31日 Siccar Point on Mars Image Credit: NASA/JPL-Caltech/MSSS; Processing & License: Kevin M. Gill Explanation: What created this unusual hill on Mars? No one is sure. A good outlook to survey the surrounding area, Siccar Point stands out from its surroundings in Gale Crater. The unusual mound was visited by the robotic Curiosity rover exploring M...
2021年9月10日，即任务的第198个火星日，NASA的毅力号火星车在被称为“罗切特”的岩石附近拍摄了这张自拍照。 影像来源：NASA/JPL-Caltech/MSSS 2021年春季，当NASA的毅力号火星车开始检查耶泽罗陨石坑底部的岩石时，科学家们感到惊讶：由于数十亿年前陨石坑拥有一个湖泊，他们原本预计会发现沉积岩，这种沉积岩是沙子和泥土在曾经潮湿的环境中沉淀时形成。相反，他们发现，地面由两种类型的火成岩组成——一种是由岩浆在地下深处形成，另一种是地表火山活动形成。 8月25日周四发表的四篇新论文描述了这些发现。在《科学》杂志上，有一篇概述了毅力号在2022年4月抵达耶泽罗古河三角洲之前对陨石坑底部的探索；同一杂志上的第二项研究详细描述了由厚岩浆体形成的独特岩石。发表在《科学进展》上的另外两篇论文详细介绍...
2022年8月6日 Stereo Phobos Image Credit: G. Neukum (FU Berlin) et al., Mars Express, DLR, ESA Explanation: Get out your red/blue glasses and float next to Phobos, grooved moon of Mars! Captured in 2004 by the High Resolution Stereo Camera on board ESA’s Mars Express spacecraft, the image data was recorded at a distance of about 200 kilometers from the mar...
Today marks 10 years since the Curiosity rover landed on Mars. Since August 2012, Curiosity has been exploring 3-mile-high Mt. Sharp in Gale Crater. The rover has climbed more than 2,000 feet (612 meters), reaching progressively younger rocks that serve as a record on how Mars has evolved from a wet, habitable planet to a cold desert environment. The photoge...
八月份的天空会发生什么？拿起你的双筒望远镜来观测行星，展望英仙座，以及和天鹅座一起翱翔。
Though Mars is the Red Planet, false-color images can help us learn about its weather and geology. This image shows a variety of wind-related features on the Red Planet near the center of Gamboa Crater. Larger sand dunes form sinuous crests and individual domes. There are tiny ripples on the tops of the dunes, only several feet from crest-to-crest. These mer...
