Dec. 22, 2022 — Expedition 68 Flight Engineer and NASA spacewalker Josh Cassada prepares a roll-out solar array for its deployment on the International Space Station’s (ISS) Port-4 truss segment as the orbiting lab flew 262 miles above the Atlantic Ocean off the coast of Namibia. Astronauts Frank Rubio and Josh Cassada conducted a spacewalk on Thursday, Dec. 22, 2022, for seven hours and eight minutes to install the new roll-out solar arrays to upgrade the station’s power system. The new ISS Roll-Out Solar Arrays (iROSAs) will increase power generation capability by up to 30%, increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts. It was the 257th spacewalk in support of space station assembly, upgrades, and maintenance, and was…

从国际空间站上拍摄到的夏威夷火山

Hawaii’s big island and its two major volcanoes Mauna Kea and Mauna Loa rest under a partly cloudy sky on Feb. 8, 2022, in this view from the International Space Station. Mauna Loa, the world’s largest active volcano had been quiet for nearly 40 years. However, in 2022, the volcano began to stir, showing increased numbers of small earthquakes and subtle swelling of certain land surfaces in September. On Nov. 27, fountains of lava began spurting from the mountain’s Northeast Rift Zone and streams of molten rock flowed to the north. Ten days into the eruption, a NASA aircraft conducted its first flight over the erupting volcano. The aircraft carried NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar system, which was used to map the volcano’s…

2022年11月12日 Eclipse in the City Image Credit & Copyright: Stan Honda Explanation: A darker Moon sets over Manhattan in this night skyscape. The 16 frame composite was assembled from consecutive exposures recorded during the November 8 total lunar eclipse. In the timelapse sequence stars leave short trails above the urban skyline, while the Moon remains immersed in Earth’s shadow. But the International Space Station was just emerging from the shadow into the sunlit portion of its low Earth orbit. As seen from New York City, the visible streak of this ISS flyover starts near a star in Taurus and tracks right to left, through the belt of Orion and over Sirius, alpha star of Canis Major. Gaps along the bright trail of the fast moving…

In this image from June 24, 2022, NASA astronauts Jessica Watkins and Bob Hines, part of NASA’s SpaceX Crew-4, work on the XROOTS space botany investigation, which used the International Space Station’s (ISS) Veggie facility to test soilless methods to grow plants. The space agricultural study could enable production of crops on a larger scale to sustain crews on future space explorations farther away from Earth and could enhance cultivation of plants in terrestrial settings such as greenhouses, contributing to better food security for people on Earth. Learn about the latest scientific research on the ISS.

Expedition 67 flight engineers Bob Hines and Jessica Watkins are all smiles in this Sept. 12, 2022, image from the International Space Station cupola. The cupola is used to monitor the arrival of spaceships and to view the Earth. Hines, Watkins, Kjell Lindgren, and European Space Agency astronaut Samantha Cristoforetti will begin the return journey to Earth on Oct. 12, 2022, with splashdown targeted for 5:41 p.m. EDT Thursday, Oct. 13. This will mark the end of a nearly six-month science mission in which members of Crew-4 conducted new and exciting scientific research in areas such as materials science, health technologies, and plant science to prepare for human exploration beyond low-Earth orbit and benefit life on Earth.

In this 20-second exposure from Oct. 5, 2022, a SpaceX Falcon 9 rocket carrying the company’s Crew Dragon spacecraft is launched on NASA’s SpaceX Crew-5 mission from our Kennedy Space Center in Florida to the International Space Station (ISS). This is the fifth crew rotation mission of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the ISS as part of the agency’s Commercial Crew Program. The crew successfully docked and entered the space station on Oct. 6, 2022. Aboard, the crew will conduct new scientific studies to prepare for human exploration beyond low-Earth orbit and benefit life on Earth.

European Space Agency astronaut Samatha Cristoforetti captured a photo of a portion of China’s Tanggula Mountains near Hala Lake as the International Space Station orbited 260 miles above the Earth on Sept. 5, 2022. Since the station began hosting human astronauts in November 2000, crew members have produced hundreds of thousands of images of the land, oceans, and atmosphere of Earth, and even of the Moon through Crew Earth Observations. Their photographs of Earth record how the planet changes over time due to human activity and natural events. This allows scientists to monitor disasters, direct response on the ground and study a number of phenomena, from the movement of glaciers to urban wildlife. Image credit: NASA 2022年9月5日，国际空间站在距地球260英里的高空绕轨道运行时，欧洲航天局宇航员萨马塔·克里斯托弗雷蒂拍摄到了中国哈拉湖附近唐古拉山脉的一部分。 自空间站于2000年11月开始接待人类宇航员以来，宇航员通过对地球的观测，拍摄了数十万张地球的陆地、海洋和大气层，甚至月球的图像。他们拍摄的地球照片记录了地球是如何随着人类活动和自然事件而随时间变化。这使科学家能够监测灾害，直接在地面作出反应，并研究从冰川运动到城市野生动物的许多现象。 影像来源：NASA
