2023年6月12日 The Largest Satellites of Earth Image Credit & Copyright: Tianyao Yang Explanation: What’s that near the Moon? It’s the International Space Station (ISS). Although the ISS may appear to be physically near the Moon, it is not — it is physically near the Earth. In low Earth orbit and circulating around our big blue marble about every 90 minutes, the ISS was captured photographically as it crossed nearly in front of the Moon. The Moon, itself in a month-long orbit around the Earth, shows a crescent phase as only a curving sliver of its Sun-illuminated half is visible from the Earth. The featured image was taken in late March from Shanghai, China and shows not only details of Earth’s largest human-made satellite, but details…

NASA astronaut Stephen Bowen and United Arab Emirates astronaut Sultan Alneyadi (partially obscured) are pictured in their spacesuits, exiting the International Space Station’s Quest airlock and beginning a spacewalk on April 28, 2023. The duo spent seven hours and one minute in the vacuum of space routing cables and installing insulation, readying the orbital outpost for its next set of roll-out solar arrays due to be installed after their delivery on the next SpaceX Dragon cargo mission.

Clouds gather over Nepal near Mount Everest (center) in this April 13, 2023, photograph from the International Space Station. This image was taken as the station orbited 263 miles above the Indian subcontinent. In addition to photography, instruments on the space station like the Compact Ocean Wind Vector Radiometer and the Temporal Experiment for Storms and Tropical Systems allow us to monitor weather and collect important data. Image Credit: NASA 2023年4月13日，国际空间站拍摄的照片中，尼泊尔珠穆朗玛峰（中）附近的云层聚集在一起。这张照片是空间站在印度次大陆上空263英里的轨道上拍摄。 除了摄影之外，空间站上的仪器，如紧凑型海洋风矢量辐射计和风暴和热带系统时间实验，使我们能够监测天气并收集重要数据。 影像来源：NASA

Stars leave streaks of light in concentric circles in this March 16, 2012, view from the International Space Station. To create this composite long exposure, NASA astronaut Don Pettit combined multiple 30-second exposures from a mounted camera on the space station into one image. The orbiting laboratory travels 5 miles per second, traveling around our planet every 90 minutes. Image Credit: NASA/Don Pettit 2012年3月16日，从国际空间站拍摄的照片中，恒星在同心圆上留下一道道光。为了制作这张合成的长时间曝光照片，NASA宇航员唐·佩蒂特将空间站上安装的相机拍摄的多张30秒曝光照片合成了一张照片。 轨道实验室每秒飞行5英里，每90分钟绕地球一周。 影像来源：NASA/Don Pettit

太平洋上的日出

太平洋上的日出

ByNASA中文

An orbital sunrise reveals cloud tops above the Pacific Ocean northeast of New Zealand as the International Space Station orbited 260 miles above on Feb. 10, 2023. Astronauts aboard the space station see 16 sunrises and sunsets per day due to their high orbital velocity—17,500 miles per hour. In the more than 20 years that people have been living aboard, the station has circumnavigated Earth tens of thousands of times. Image Credit: NASA 2023年2月10日，国际空间站在新西兰东北部的太平洋上空260英里轨道上运行，轨道上的日出显示出太平洋上空的云顶。由于轨道速度高（每小时17,500英里），空间站上的宇航员每天能看到16次日出和日落。在人们居住在空间站的20多年里，空间站已经环绕地球数万次。 影像来源：NASA
