从空间站拍摄到的飓风弗莱迪

ByNASA中文 2023年3月7日

Cyclone Freddy is pictured northeast of the island nation of Mauritius from the International Space Station as it orbited 267 miles above the Indian Ocean on Feb. 20, 2023. On the space station are two NASA-built weather instruments, the Compact Ocean Wind Vector Radiometer (COWVR) and the Temporal Experiment for Storms and Tropical Systems (TEMPEST), that track tropical cyclones like Freddy. Launched in late 2021 to the space station, COWVR measures the speed and direction of wind at the ocean surface, and TEMPEST provides atmospheric water vapor measurements.

从空间站拍摄的闪耀的金星、木星、月球

ByNASA中文 2023年3月2日

Former NASA astronaut Scott Kelly snapped this photo of the Earth’s crescent, the Moon, Venus, and Jupiter (from top to bottom) on Aug. 6, 2015, while he was aboard the International Space Station. These celestial bodies have been quite close in the night sky; on March 1, Venus and Jupiter were nearest to each other.

Astronaut John Glenn enters the Mercury spacecraft, Friendship 7, prior to the launch of Mercury-Atlas 6 (MA-6) on Feb. 20, 1962. The MA-6 mission was the first crewed orbital flight and Glenn became the first American to orbit the Earth during the three-orbit, five-hour MA-6 mission.

蓝色的告别

ByNASA中文 2023年2月23日

A blue halo glows around Pluto’s receding crescent in this parting image taken by NASA’s New Horizons spacecraft on July 14, 2015. At the time of this shot, New Horizons was 120,000 miles (200,000 kilometers) away from Pluto. Shown in approximate true color, the picture was constructed from a mosaic of six black-and-white images from the Long Range Reconnaissance Imager, with color added from a lower resolution Ralph/Multispectral Visible Imaging Camera color image. Scientists believe the haze is a smog resulting from the action of sunlight on methane and other molecules in Pluto’s atmosphere. This reaction produces a complex mixture of hydrocarbons that accumulate into small haze particles which scatter blue light. As they settle down through the atmosphere, the haze particles form numerous intricate…

NASA庆祝国家工程师周：来自詹姆斯·斯托克斯的观点

ByNASA中文 2023年2月22日

Jamesa Stokes’ path to being an engineer at NASA started out on a completely different road. While she loved and excelled at math and science, she was also passionate about studio art, her first major in college. But knowing that science can also be a creative pursuit, she switched to physics and embarked on a journey to NASA when she reached grad school. Stokes, who received her bachelor’s degree in Physics from Auburn University and a Ph.D. in Materials Science and Engineering from the Pennsylvania State University, was awarded a graduate fellowship to conduct research at NASA Glenn. She later became a NASA intern and converted to a full-time Materials Research Engineer when she finished her Ph.D. “Working at NASA means tackling the bigger problems…

练习月球行走

ByNASA中文 2023年2月16日

Two Joint Extravehicular Activity Test Team Field Test #3 (JETT3) mission members work on sample collection on the remote, rocky, high-desert terrain of the S P Crater near Flagstaff, Arizona, on Oct. 5, 2022. JETT3 was the third simulated moonwalk in preparation for future Artemis missions; during Artemis III, astronauts will visit the lunar South Pole region, which has never been explored by humans. The S P Crater has unique terrain and geology, as well as minimal communications infrastructure that make it a great location for an analog mission. Image Credit: NASA/Bill Stafford 2022年10月5日，两名联合舱外活动测试团队3号现场测试（JETT3）任务成员在亚利桑那州弗拉格斯塔夫附近的S P陨石坑偏远、多岩石、高沙漠地形上进行样本采集。 JETT3是第三次模拟月球行走，为未来的阿尔忒弥斯任务做准备；在阿尔忒弥斯三号任务期间，宇航员将访问人类从未探索过的月球南极地区。S P陨石坑拥有独特的地形和地质以及最少的通讯基础设施，使其成为模拟任务的绝佳地点。影像来源：NASA/Bill Stafford
