Twenty-five years ago in Feb. 1995, astronaut Bernard Harris (right) became the first African American to perform a spacewalk. In this image, he and fellow STS-63 astronaut Michael Foale, prepare to exit space shuttle Discovery’s airlock to began their spacewalk. The pair would test new insulation to protect astronauts from the cold, but the Mission Co...
2020 February 12 Star Trails of the North and South Image Credit & Copyright: Saeid Parchini Explanation: What divides the north from the south? It all has to do with the spin of the Earth. On Earth’s surface, the equator is the dividing line, but on Earth’s sky, the dividing line is the Celestial Equator — the equator’s projectio...
1999年，科学家们首次提出了太阳轨道飞行器任务，并计划在2008年至2013年期间执行发射任务，但由于技术困难和一些任务重组，延期至今天发射升空。 太阳轨道飞行器将首次拍摄太阳南北极。 Credit:NASA 历史性的发射 北京时间今天中午12时3分，太阳轨道飞行器发射升空，它将首次拍摄太阳的南北极。 Credit: @ulalaunch 下面是太阳轨道飞行器发射升空画面，在后面的画面（这段视频中没有）中还看到了火箭和满月的合影。 Credit:NASA TV 火箭（中间下方小点）升空后与满月的合影。 Credit：NASA TV 太阳轨道飞行器发射升空53分钟后，星箭分离，随后几分钟，任务小组与太阳轨道飞行器建立了联系。 太阳轨道飞行器发射和部署时序 Credit：ESA ESA接收到的太阳轨道飞行器的频谱...

Northrop Grumman’s 13th contracted cargo resupply mission with NASA to the International Space Station will deliver about 7,500 pounds of science and research, crew s...
2020 February 10 Solar Eclipse over the UAE Image Credit & Copyright: Joshua Cripps Explanation: What’s happening behind that camel? A partial eclipse of the Sun. About six and a half weeks ago, the Moon passed completely in front of the Sun as seen from a narrow band on the Earth. Despite (surely) many camels being located in this narrow band, onl...
