古老的河流正在帮助NASA的毅力号火星车完成任务
这位六轮地质学家在寻找不同岩石样本的过程中得到了一些帮助，这些岩石样本可能会被带到地球进行更深入的研究。
星城卫星发射升空
On July 17, 2023, NASA’s four Starling CubeSats successfully deployed after having launched aboard Rocket Lab’s Electron rocket, shown in this image. NASA sent the team of four six-unit (6U)-sized CubeSats into orbit around Earth to see if they’re able to cooperate on their own, without real-time updates from mission control. The four CubeSats will fly in two different formations to test several technologies paving the way towards a future where swarms of satellites can cooperate to do science in deep space. The Starling mission will last at least six months, positioning the spacecraft about 355 miles above Earth and spaced about 40 miles apart.

月船3号发射前往月球
2023年7月19日 Chandrayaan-3 Launches to the Moon Image Credit & Copyright: Sruthi Suresh (Space Group) Explanation: Birds don’t fly this high. Airplanes don’t go this fast. The Statue of Liberty weighs less. No species other than human can even comprehend what is going on, nor could any human just a millennium ago. The launch of a rocket bound for space is an event that inspires awe and challenges description. Pictured here last week, the Indian Space Research Organization‘s LVM3 rocket blasted off from the Satish Dhawan Space Centre on Sriharikota Island, India. From a standing start, the 600,000+ kilogram rocket ship lifted the massive Chandrayaan-3 off the Earth. The Chandrayaan-3 mission is scheduled to reach the Moon in late August and land a robotic rover near…
NASA的IXPE让天文学家对耀变体有了新的发现
一个由天体物理学家组成的国际团队，利用NASA的X射线成像偏振探测器（IXPE）的新数据，发表了关于名为马卡里安421的耀变体的发现，并提供了一些令人惊讶的结果。
北非上空云层密布
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
拉帕尔马天文台上空的银河
2023年7月18日 Milky Way above La Palma Observatory Image Credit & Copyright: Marcin Rosadziński Explanation: What’s happening in the night sky? To help find out, telescopes all over the globe will be pointing into deep space. Investigations will include trying to understand the early universe, finding and tracking Earth-menacing asteroids, searching for planets that might contain extra-terrestrial life, and monitoring stars to help better understand our Sun. The featured composite includes foreground and background images taken in April from a mountaintop on La Palma island in the Canary Islands of Spain. Pictured, several telescopes from the Roque de los Muchachos Observatory are shown in front of a dark night sky. Telescopes in the foreground include, left to right, Magic 1, Galileo, Magic 2, Gran Canarian, and…
NASA的星城任务将一群卫星送入轨道
今年7月，NASA将派遣一个由四个六单元（6U）大小的立方体卫星组成的团队进入绕地球轨道，看看他们是否能够在没有任务控制实时更新的情况下独自合作。
阿尔忒弥斯机组人员的全电动载具
One of three specially designed, fully electric, environmentally friendly crew transportation vehicles for Artemis missions sits at Launch Pad 39B at NASA’s Kennedy Space Center in Florida on July 11, 2023. These zero-emission vehicles, manufactured by Canoo Technologies Inc., will take Artemis crews on the final Earth-bound leg of their journey to the Moon before boarding their rocket and spacecraft. The new vehicles are customized to accommodate NASA’s unique specifications for Artemis missions while also paying homage to the legacy of the agency’s human spaceflight and space exploration efforts. Many aspects of the design, from the interior and exterior markings to the color of the vehicles to the wheel wells, were chosen by a creative team that included the Artemis launch director and representatives from…
狮子CW恒星周围的壳层与光弧
2023年7月17日 Shells and Arcs around Star CW Leonis Image Credit: ESA, NASA, Hubble, T. Ueta (U. Denver), H. Kim (KASI) Explanation: What’s happening around this star? No one is sure. CW Leonis is the closest carbon star, a star that appears orange because of atmospheric carbon dispersed from interior nuclear fusion. But CW Leonis also appears engulfed in a gaseous carbon-rich nebula. What causes the nebula’s complexity is unknown, but its geometry of shells and arcs are surely intriguing. The featured image by the Hubble Space Telescope details this complexity. The low surface gravity of carbon stars enhances their ability to expel carbon and carbon compounds into space. Some of this carbon ends up forming dark dust that is commonly seen in the nebulas of…
阿尔卑斯山上空的流星与银河
2023年7月16日 Meteor and Milky Way over the Alps Image Credit & Copyright: Nicholas Roemmelt (Venture Photography) Explanation: Now this was a view with a thrill. From Mount Tschirgant in the Alps, you can see not only nearby towns and distant Tyrolean peaks, but also, weather permitting, stars, nebulas, and the band of the Milky Way Galaxy. What made the arduous climb worthwhile this night, though, was another peak — the peak of the 2018 Perseids Meteor Shower. As hoped, dispersing clouds allowed a picturesque sky-gazing session that included many faint meteors, all while a carefully positioned camera took a series of exposures. Suddenly, a thrilling meteor — bright and colorful — slashed down right next to the nearly vertical band of the Milky Way. As…
