土星环的景观

This artist’s illustration shows the Cassini spacecraft in orbit around Saturn. Cassini made 22 orbits that swooped between the rings and the planet before ending its 13-year tour of the ringed planet on Sept. 15, 2017, with a final plunge into Saturn. Cassini spacecraft shared the wonders of Saturn and its family of icy moons—taking us to astounding w...

太阳帆小行星任务准备在阿尔忒弥斯 I号任务上发射

编者注:本文已被更新,以反映 NEA Scout 相机分辨率的正确公制转换。 NASA的近地小行星航天器被安全地藏在佛罗里达州肯尼迪航天中心的NASA强大的太空发射系统(SLS)火箭中。太阳航行立方体卫星是搭载阿尔忒弥斯I号任务的几个次级有效载荷之一,阿尔忒弥斯 I号任务是NASA SLS和猎户座飞船的首次综合飞行。 工程师为NEA Scout的整合和运输做好准备。 影像来源:NASA NEA Scout是一个鞋盒大小的小型航天器,它被封装在一个分配器中,并连接到连接SLS火箭和猎户座航天器的转接环上。阿尔忒弥斯 I号任务将是一次无人飞行测试。它还为几个立方体卫星提供深空运输,为像 NEA Scout 这样的小型航天器作为阿尔忒弥斯计划的一部分到达月球和更远的地方提供机会。 NEA Scout航天器在NASA马...

庆祝在木星的5周年

On July 4, 2016, our Juno spacecraft arrived at Jupiter on a mission to peer through the gas giant planet’s dense clouds and answer questions about the origins of our solar system. Since its arrival, Juno has provided scientists with a treasure trove of data about the planet’s origins, interior structures, atmosphere and magnetosphere. Juno is the first miss...

向航天飞机收尾工作人员致敬

This uniform in the center of this image belonged to one of the unsung heroes of the Space Shuttle Program – Travis Thompson, former Closeout Crew Lead. The closeout crew was responsible for assisting the astronauts to strap into the shuttle’s crew module and take care of any other last-minute needs that arose. Ultimately, they close and seal the crew ...

火星直升机为火星车团队揭示了有趣的地形

NASA的机智号火星直升机在7月5日第九次飞行期间拍摄到了毅力号火星车的足迹。在左上角可以看到直升机的一部分起落架。 影像来源:NASA/JPL-Caltech 机智号的第九次飞行提供的图像将帮助毅力号火星车团队制定未来的科学计划。 7月5日,NASA的机智号火星直升机在其雄心勃勃的第九次飞行中拍摄到的照片,为与毅力号火星车合作的科学家和工程师提供了一个前所未有的探索未来道路的机会。机智号让我们对不同岩层的起点和终点有了新的认识,每一层都是一个时间胶囊,用来记录这个地方的古代气候是如何变化。这次飞行还发现了探测器在探索杰泽罗陨石坑时可能会遇到的障碍。 这次飞行是为了测试直升机的空中侦察能力,它飞过了一个昵称为“Séítah”的沙丘地带。毅力号正绕着这些沙丘向南绕行,这对这个六轮探测器来说穿越沙丘太冒险了。 来自...
