智利的火山羽流

Chile’s Villarrica volcano emits steam and other volcanic gases in this photo taken from the International Space Station on Jan. 17, 2023. The gases come from a series of minor explosions—called Strombolian eruptions—that have been ongoing at Villarrica since October 2022. Located along Chile’s southern Andes, Villarrica is one of the most active and dangerous volcanoes in South America; it typically erupts every three to six years.

里根总统呼吁建立空间站

里根总统呼吁建立空间站

ByNASA中文

On Jan. 25, 1984, President Ronald Reagan used his State of the Union address to call for NASA to build a permanent crewed space station. While Reagan’s speech took place in a broader sociopolitical context of generally heightened tensions with the Soviet Union, his remarks foreshadowed the international cooperation that has characterized the International Space Station. He called for NASA to invite other countries to participate “so we can strengthen peace, build prosperity, and expand freedom for all who share our goals.” Credit: National Archives and Records Administration 1984年1月25日，罗纳德·里根总统在他的国情咨文中呼吁NASA建立一个永久性的载人空间站。 虽然里根的演讲是在与苏联紧张关系普遍加剧更广泛的社会政治背景下进行，但他的演讲预示着国际空间站的国际合作。他呼吁NASA邀请其他国家参与，“这样我们就可以为所有与我们有共同目标的人加强和平，建设繁荣，扩大自由。” 影像来源：National Archives and Records Administration

Snow and ice cover mountains of the Tien Shan range in this photograph taken from the International Space Station (ISS) on Feb. 9, 2022. The Tien Shan—which means heavenly mountains in Chinese—is one of the largest mountain ranges in the world, extending approximately 2,500 kilometers (1,550 miles) across Central Asia, mostly along the border between Kyrgyzstan and China. The glaciers covering these slopes are a crucial source of water for nearby farmers and residents. See more wintery photos from the ISS. Image Credit: NASA 2022年2月9日，在国际空间站拍摄的这张照片中，冰雪覆盖着天山山脉。天山，中文意思是“天上的山”，是世界上最大的山脉之一，横跨中亚大约2,500公里（1,550英里），主要沿着吉尔吉斯斯坦和中国的边界。覆盖这些斜坡的冰川是附近农民和居民的重要水源。 查看更多来自国际空间站的冬季照片。 图片来源：NASA

NASA astronaut and Expedition 68 Flight Engineer Frank Rubio is all smiles as he observes the behavior of a free-flying water bubble inside the International Space Station’s (ISS) Kibo laboratory module on Oct. 10, 2022. Fluid physics is the study of liquid and gas motion and the effects of forces on liquids and gases. The International Space Station’s low-gravity environment offers a unique place to study fluid physics. Nearly weightless conditions allow researchers to observe and control fluid phenomena in ways not possible on Earth. Learn more about fluid physics research on the ISS.

NASA astronaut and Expedition 68 Flight Engineer Nicole Mann peers through one of the seven windows in the cupola, the International Space Station’s “window to the world” on Jan. 2, 2023. Mann displays the U.S. flag inside the cupola in the window next to her. The cupola is designed for watching operations outside the station such as robotic activities, the approach of vehicles, and spacewalks. Its windows provide spectacular views of Earth and celestial objects.

2023年1月7日 Space Stations in Low Earth Orbit Image Credit & Copyright: Zarcos Palma Explanation: On January 3, two space stations already illuminated by sunlight in low Earth orbit crossed this dark predawn sky. Moving west to east (left to right) across the composited timelapse image China’s Tiangong Space Station traced the upper trail captured more than an hour before the local sunrise. Seen against a starry background Tiangong passes just below the inverted Big Dipper asterism of Ursa Major near the peak of its bright arc, and above north pole star Polaris. But less than five minutes before, the International Space Station had traced its own sunlit streak across the dark sky. Its trail begins just above the W-shape outlined by the bright stars of…
