The core of NASA’s Europa Clipper spacecraft has taken center stage in the Spacecraft Assembly Facility at the agency’s Jet Propulsion Laboratory in Southern California. Standing 10 feet (3 meters) high and 5 feet (1.5 meters) wide, the craft’s main body will for the next two years be the focus of attention in the facility’s ultra-hygienic High Bay 1 as engi...

韦伯的NIRCam从三个滤镜——F360M（红色）、F212N（黄绿色）和F150W2（青色）拍摄的木星合成图像，并校准了经因行星自转而形成的误差。 影像来源：NASA, ESA, CSA, Jupiter ERS Team; image processing by Judy Schmidt. 伴随着巨大的风暴、强风、极光以及极端的温度和压力条件，木星发生了很多事情。现在，NASA的詹姆斯·韦伯太空望远镜捕捉到了这颗行星的新图像。韦伯对木星的观测将为科学家提供更多关于木星内部生命的线索。 “说实话，我们真的没想到它会这么好。”加州大学伯克利分校名誉教授、行星天文学家伊姆克·德·佩特说。德帕特尔与巴黎天文台教授蒂埃里·福切特一起领导了对木星的观测，这是韦伯早期发布科学计划国际合作的一部分。韦伯本身是一项由NASA...
2022年8月22日 Earth’s Recent Climate Spiral Video Credit: NASA’s Scientific Visualization Studio Explanation: Is our Earth warming? Compared to the past 250 million years, the Earth is currently enduring a relative cold spell, possibly about four degrees Celsius below average. Over the past 120 years, though, data indicate that the average global te...
此处显示的是阿尔忒弥斯3号任务的13个候选着陆区域的渲染图。每个区域大约为9.3×9.3英里（15×15公里）。着陆点是这些区域内半径约为328英尺（100米）的位置。 影像来源：NASA 随着NASA准备在阿尔忒弥斯任务的带领下将宇航员送回月球，该机构已经确定了月球南极附近的13个候选着陆区。每个地区都包含多个阿尔忒弥斯3号任务的潜在着陆点，这将是阿尔忒弥斯任务中第一个将宇航员带到月球表面的任务，其中包括第一位踏上月球的女性。 “选择这些区域意味着，我们距离自阿波罗计划以来首次重返月球又迈进了一大步。”华盛顿NASA总部阿尔忒弥斯运动发展部副主任马克·基拉希奇说。“当我们这样做时，它将不同于以往的任何任务，宇航员将冒险进入人类此前未探索过的黑暗区域，并为未来的长期停留奠定基础。” NASA确定了阿尔忒弥斯3号...

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 ...
