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
An international team of astronomers using NASA’s James Webb Space Telescope has obtained an in-depth inventory of the deepest, coldest ices measured to date in a molecular cloud. In addition to simple ices like water, the team was able to identify frozen forms of a wide range of molecules, from carbonyl sulfide, ammonia, and methane, to the simplest complex organic molecule, methanol. This is the most comprehensive census to date of the icy ingredients available to make future generations of stars and planets, before they are heated during the formation of young stars. This image from the telescope’s Near-Infrared Camera (NIRCam) features the central region of the Chamaeleon I dark molecular cloud, which resides 630 light-years away. The cold, wispy cloud material (blue, center) is…
iss068e041215 (Jan. 20, 2023) — NASA astronaut and Expedition 68 Flight Engineer Nicole Mann is pictured in her Extravehicular Mobility Unit, or spacesuit, during her first spacewalk. She and fellow spacewalker Koichi Wakata (out of frame) of the Japan Aerospace Exploration Agency installed a modification kit on the International Space Station’s starboard truss structure that will enable the future installation of the orbiting lab’s next roll-out solar array. iss068e041215（2023年1月20日）——NASA宇航员兼第68号远征队飞行工程师妮可·曼在第一次太空行走时穿着舱外机动装置（或宇航服）。她和日本宇宙航空研究开发署的太空行走同伴若田光一（画面外）在国际空间站的右舷桁架结构上安装了一个改装套件，这将使未来能够安装轨道实验室的下一个展开式太阳能电池阵。
Expedition 68 Flight Engineers Nicole Mann of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency are pictured on Jan. 12, 2023, during a fit check of their spacesuits inside the Quest airlock ahead of a planned spacewalk to upgrade the International Space Station’s power generation system. The spacewalk began on Jan. 20, 2023, at approximately 8:15 a.m. EST and was expected to last six and a half hours.

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
Snoopy, the zero gravity indicator that flew aboard Orion during the Artemis I mission, wears a smile after being unpacked from his transport case on Jan. 5, 2023. Zero gravity indicators are small items carried aboard spacecraft that provide a visual indicator when a spacecraft has reached the weightlessness of microgravity. NASA has held an association with Snoopy since the Apollo Era – the character has contributed to the excitement for NASA human spaceflight missions, helping inspire generations to dream big, and is a symbol of NASA’s safety culture and mission success.

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.

The Artemis I Orion capsule is secured on a platform inside the Multi-Payload Processing Facility (MPPF) at Kennedy Space Center in Florida in this image from Jan. 6, 2023. Orion splashed down on Dec. 11, 2022 and was transported back to Kennedy for de-servicing inside the MPPF. During Orion’s 25.5-day trip beyond the Moon and back, it flew farther than any designed to carry humans to deep space and safely return them to Earth, paving the way for human deep space exploration and demonstrating NASA’s commitment and capability to extend human presence to the Moon and beyond.
