Woody Hoburg took this photo of Laguna Verde’s inviting waters as the International Space Station orbited 264 miles (425 km) over South America on July 7, 2023. Laguna Verde, which has an altitude of over 14,000 feet (4,300 meters), is located in the Andes mountains of Chile. Even taller landmarks surround the high-altitude lake, including Ojos del Salado—the tallest peak in Chile and the highest volcano on Earth. See more photos of Earth taken by astronauts on the space station. Image Credit: NASA/Woody Hoburg 2023年7月7日，国际空间站在南美洲上空绕轨道飞行264英里（425公里）时，伍迪·霍伯格拍摄了这张绿湖迷人水域的照片。绿湖位于智利的安第斯山脉，海拔超过14,000英尺（4,300米）。高海拔湖泊周围甚至还有更高的地标，包括智利最高峰和地球上最高的火山——奥霍斯·德尔·萨拉多火山。 查看更多由宇航员在空间站拍摄的地球照片。 图片来源: NASA/Woody Hoburg

As the International Space Station orbited 259 miles above North Africa, swirls of clouds covered the sky. To the bottom right of the image, one of the station’s roll-out solar arrays peeks through. 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, it has circumnavigated Earth tens of thousands of times. Image Credit: NASA 当国际空间站在北非上空259英里的轨道上运行时，天空布满了漩涡状的云。在图像的右下方，空间站的太阳能电池阵列隐约可见。由于轨道速度很高(17500英里/小时)，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，它已经绕地球飞行了数万次。 影像来源：NASA

巴西的新月形沙丘

巴西的新月形沙丘

ByNASA中文

Former NASA astronaut Jack Fischer captured this photograph of Lagoa dos Barros and crescent-shaped barchan dunes on the Atlantic coastline of southern Brazil on July 9, 2017, while aboard the International Space Station. Barchan dunes are sand dunes that form in areas with one wind direction and little vegetation. In this case, fierce winds from the Western Atlantic sculpt the sand along the coast into distinctive crescent shapes. The tips of barchan dunes point downwind, showing the prevailing wind direction. These fragile formations act as barriers keeping the wind and waves from penetrating inland, blunting the effect of storms and minimizing coastal erosion. See more photos of Earth taken from space. Image Credit: NASA/ Jack Fischer 2017年7月9日，前NASA宇航员杰克·菲舍尔在国际空间站上拍摄了这张巴西南部大西洋海岸线上的拉戈亚·多斯·巴罗斯和新月形沙丘的照片。 新月形沙丘是在单一风向和植被稀少的地区形成的沙丘。在这种情况下，来自西大西洋的强风将海岸的沙子塑造成独特的新月形。新月形沙丘的尖端指向下风，表明盛行风向。这些脆弱的地层充当屏障，阻止风和海浪穿透到内陆，减弱风暴的影响，最大限度地减少海岸侵蚀。 查看更多从太空拍摄的地球照片。 图片来源: NASA/ Jack Fischer

The last rays of an orbital sunset begin fading in Earth’s atmosphere silhouetting the cloud tops in this June 24, 2023, photograph from the International Space Station as it orbited 271 miles above the southernmost tip of South America. The space station makes 16 orbits of the Earth in 24 hours, so astronauts on the orbital outpost see 16 sunrises and sunsets. Get more quick facts about the International Space Station. Image Credit: NASA 2023年6月24日，国际空间站在南美洲最南端上空271英里的轨道上拍摄的这张照片显示，轨道日落的最后一道光线开始在地球大气层中消退，勾勒出云顶的轮廓。 国际空间站在24小时内绕地球运行16圈，因此空间站上的宇航员可以看到16次日出和日落。了解更多关于国际空间站的快速事实。 影像来源：NASA

2023年6月17日 Planet Earth at Night II Video Credit: NASA, Gateway to Astronaut Photography, ISS Expedition 53; Music: The Low Seas (The 126ers) Explanation: Recorded during 2017, timelapse sequences from the International Space Station are compiled in this serene video of planet Earth at Night. Fans of low Earth orbit can start by enjoying the view as green and red aurora borealis slather up the sky. The night scene tracks from northwest to southeast across North America, toward the Gulf of Mexico and the Florida coast. A second sequence follows European city lights, crosses the Mediterranean Sea, and passes over a bright Nile river in northern Africa. Seen from the orbital outpost, erratic flashes of lightning appear in thunder storms below and stars rise above the…

In this long exposure photo from June 5, 2023, a SpaceX Falcon 9 rocket creates a beam of light as it launches from Kennedy Space Center in Florida. The 28th commercial resupply mission of the Cargo Dragon spacecraft brought new science investigations, food, supplies, and equipment to the International Space Station, including IROSAs (International Space Station Roll Out Solar Arrays) that will help provide a 30% increase in power for space station research and operations once installed.

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…

The last rays of an orbital sunset illuminate the cloud tops above the Pacific Ocean off the coast of Japan, providing a dramatic background for the SpaceX CRS-28 Dragon cargo craft as it approached the International Space Station for docking on June 6, 2023. The uncrewed Dragon spacecraft carried scientific experiments and technology demonstrations, including studies of plant adaptation to stress and genetic structures called telomeres and deployment of satellite projects designed by students in Canada. Image credit: NASA 2023年6月6日，轨道日落的最后一道光线照亮了日本海岸外太平洋上空的云顶，为SpaceX公司的CRS-28龙货运飞船接近国际空间站进行对接提供了一个戏剧性的背景。 无人驾驶的龙飞船进行了科学实验和技术演示，包括研究植物对压力的适应和被称为端粒的遗传结构，以及部署由加拿大学生设计的卫星项目。 影像来源：NASA
