旅行者1号升空,迈向星际之旅

On Sept. 5, 1977, NASA’s Voyager 1 spacecraft lifts off atop its Titan/Centaur-6 launch vehicle from Launch Complex 41 at Cape Canaveral Air Force Station, now Cape Canaveral Space Force Station, in Florida. Voyager 1 and its twin, Voyager 2, were originally launched to conduct closeup studies of Jupiter and Saturn, Saturn’s rings, and the larger...

星际旅者

2022年9月9日 Interstellar Voyager Poster Illustration Credit: NASA, JPL-Caltech, Voyager Explanation: Voyager 1 and Voyager 2 were launched in 1977 on a grand tour of the outer planets of the Solar System. They have become the longest operating and most distant spacecraft from Earth. Both have traveled beyond the heliosphere, the realm defined by the influence ...

旅行者1号的外行星任务开始了

The Voyager mission was designed to take advantage of a rare geometric arrangement of the outer planets in the late 1970s and the 1980s which allowed for a four-planet tour with a minimum of propellant and trip time. This layout of Jupiter, Saturn, Uranus and Neptune, which occurs about every 175 years, allows a spacecraft on a particular flight path to swin...

工程师解决了旅行者1号上的数据故障

旅行者号航天器的高增益天线位于NASA航天器的图示中心,是由姿态铰接和控制系统(AACS)控制的一个组件。 影像来源:NASA/JPL-Caltech 航天器上的一个关键系统正在发送有关其状态的乱码数据。工程师已经解决了这个问题,但仍在寻找根本原因。 工程师们已经修复了一个影响NASA旅行者1号航天器数据的问题。今年早些时候,保持旅行者1号天线指向地球的航天器姿态关节和控制系统(AACS),尽管其运行正常,但开始向任务控制员发送有关其健康和活动的乱码信息。在继续收集和返回科学数据的过程中,航天器的其余部分看起来也很健康。 此后,该团队找到了乱码信息的来源:AACS开始通过一台已知几年前停止工作的机载计算机发送遥测数据,而这台计算机破坏了信息。 旅行者的项目经理苏珊娜·多德表示,当他们怀疑这是问题所在时,他们选择...

NASA科学家通过测试引力帮助探测暗能量

这张图片是NASA詹姆斯·韦伯太空望远镜发布的首张图片,展示了星系团 SMACS 0723。由于一种称为引力透镜的现象,一些星系看起来被涂抹或拉伸。这种效应可以帮助科学家绘制宇宙中暗物质的存在图。 影像来源:NASA, ESA, CSA, and STScI 天体物理学中最大的谜题之一能否通过重新修正阿尔伯特·爱因斯坦的引力理论来解决?一项由NASA科学家共同撰写的新研究称,目前还不能。 宇宙正在加速膨胀,科学家们还不知道原因。这一现象似乎与研究人员对引力对宇宙影响的理解相矛盾:就像你把一个苹果扔到空中,它持续上升,并且速度越来越快。这种被称为暗能量的加速的原因仍然是个谜。 国际暗能量调查局利用智利的维克多·M·布兰科4米望远镜进行的一项新研究,标志着最新的努力,以确定这是否只是一个误解:即对整个宇宙范围内引力...

旅行者1号看到了大红斑

Launched in 1977, the twin Voyager probes are NASA’s longest-operating mission and the only spacecraft ever to explore interstellar space. 45 years on, Voyager 1 and 2 continue to provide us with observations of the farthest reaches of space. Our Voyager 1 spacecraft zoomed toward Jupiter in January and February 1979, capturing hundreds of images of Jupiter ...

旅行者号拍摄到的木星大红斑

This view of Jupiter was taken by Voyager 1. This image was taken through color filters, recombined to produce the color image, and assembled from three black and white negatives by the Image Processing Lab at Jet Propulsion Laboratory. The twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-...
