保护地球，探索宇宙，发现文明
In this image from June 2023, an engineer watches a development model rover during a test for NASA’s Cooperative Autonomous Distributed Robotic Exploration (CADRE) technology demonstration in the Mars Yard at NASA’s Jet Propulsion Laboratory in Southern California. The team tested a new wheel design, surface navigation software, and mobility capabilities, am...
On July 17, 2023, NASA’s four Starling CubeSats successfully deployed after having launched aboard Rocket Lab’s Electron rocket, shown in this image. NASA sent the team of four six-unit (6U)-sized CubeSats into orbit around Earth to see if they’re able to cooperate on their own, without real-time updates from mission control. The four CubeSats will fly in tw...
今年7月，NASA将派遣一个由四个六单元（6U）大小的立方体卫星组成的团队进入绕地球轨道，看看他们是否能够在没有任务控制实时更新的情况下独自合作。
The Moon makes a stunning backdrop for the successful launch of the third in a series of polar-orbiting weather satellites for the National Oceanic and Atmospheric Administration (NOAA) and our Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) on Nov. 10 at 4:49 a.m. EST from Vandenberg Space Force Base in California. A United Launch Alliance...
A team of roboticists from NASA’s Johnson Space Center in Houston have applied their expertise in making robots for deep space to designing a fully electric shape-changing submersible robot that will cut costs for maritime industries. Aquanaut, seen here during testing in the giant pool at Johnson’s Neutral Buoyancy Lab, opens its shell and turns its arms, c...
NASA利用激光向地球发送信息和从地球发送信息，利用看不见的光束穿越天空，发送数 TB 的数据（图片和视频）以增加我们对宇宙的了解。这种能力被称为激光或光学通信，尽管这些对眼睛安全的红外光束不能被人眼看到。 “我们对未来几年激光通信的前景感到兴奋。”华盛顿NASA总部负责空间通信和导航（SCaN）的副主管兼项目经理巴德里·尤尼斯说。“这些任务和演示开启了NASA新的的光之十年，在此期间，NASA将与其他政府机构和商业部门合作，大幅扩大未来太空探索的通信能力，创造充满活力和强劲的经济机遇。” 激光通信系统为任务提供了更高的数据传输速率，这意味着与传统无线电波相比，它们可以在一次传输中发送和接收更多信息。此外，该系统更轻、更灵活、更安全。激光通信可以补充目前大多数NASA任务使用的射频通信。 激光通信中继演示（LC...
This tunnel view looking up from Level 5 is of the Zero Gravity Facility at Lewis Research Center, now known as John H. Glenn Research Center at Lewis Field, and was taken in Cleveland, Ohio, on Sept. 12, 1966. The tower dropped 460 feet and allowed scientists to perform 5.18 seconds of microgravity research. By comparison, the Washington Monument is 555 fee...
A NASA CubeSat designed to test a unique lunar orbit is safely in space and on the first leg of its journey to the Moon. The spacecraft is heading toward an orbit intended in the future for Gateway, a lunar space station built by the agency and its commercial and international partners that will support NASA’s Artemis program, including astronaut missions. T...
2022年6月28日，周二，在新西兰马希亚半岛的火箭实验室1号发射场，地月自主定位系统技术操作和导航实验（或称CAPSTONE）搭载火箭实验室的电子火箭发射升空。 影像来源：Rocket Lab NASA的立方体卫星（CubeSat）设计用于测试一个独特的月球轨道，目前它在太空中安全运行，并进入了月球之旅的第一段路程。该航天器正朝着未来计划用于门户（Gateway）的轨道前进，门户是该机构及其商业和国际合作伙伴建造的一个月球空间站，将支持NASA的阿尔忒弥斯项目，包括宇航员任务。 “CAPSTONE是一个例子，说明了与商业伙伴合作对NASA探索月球及其他星球的雄心计划是多么关键。”空间技术任务理事会副局长吉姆·勒特说。“我们对此次任务的成功开始感到兴奋，并期待着CAPSTONE到达月球后能做些什么。” CAPS...
Since the days of NASA’s Apollo program, astronauts have documented (and contended with) how liquids behave differently in microgravity than they do on Earth – coalescing into floating spheres instead of bottom-heavy droplets. Now, researchers have demonstrated this effect with a much more exotic material: gas cooled to nearly absolute zero (minus 459 degree...
