SpaceX在新的一年里完成了它的首次发射,并最终完成了75颗铱卫星。_我的网站

一 | 1月12日,Verge报告称,SpaceX于今早完成了其在加利福尼亚州的第一次猎鹰9号火箭发射任务,将长期客户铱的所有10颗卫星送入近地轨道。从那时起,SpaceX利用无人驾驶的飞船回收了猎鹰9号火箭,成功回收的火箭总数达到33枚。

Chinese scientists on Wednesday released the first complete set of observational images captured by China's new-generation ground-based infrared telescope, filling a gap in the country's near-infrared astronomical observation capabilities and reducing reliance on foreign infrared detector technology, China News Service reported on Wednesday. 
The 80-centimeter near-infrared telescope was installed at Saishiteng Mountain, Lenghu township, Northwest China's Qinghai Province in October 2024. Jointly developed by Sun Yat-sen University and several partner institutions, the telescope is China's first to achieve scientific imaging in the 1.2-micrometer J band and 2.2-micrometer K band using domestically developed scientific-grade InGaAs and HgCdTe detectors. 
The telescope enables unattended remote operations, and can lock onto any target in the sky within 15 seconds. Its infrared capability allows it to see through interstellar dust, enabling it to observe cold and distant celestial objects that are difficult for optical telescopes to capture. 
According to Ma Bin, a professor at the School of Physics and Astronomy, Sun Yat-sen University who led the research team that released the infrared telescope's observational images, all three of the telescope's core astronomical observation capabilities were fully validated during operation. 
It rapidly responded to and tracked multiple gamma-ray bursts and supernova events, recording the evolution of their infrared afterglows following the explosions. It continuously monitored brown dwarfs, precisely capturing periodic variations in their atmospheric brightness. Using image-stacking technology, it also observed active galaxies billions of light-years away. 
Since its deployment in Lenghu, the system has supported infrared observations for more than 10 Chinese research institutions, accumulating valuable experience for the construction of future large-scale infrared telescopes. 
Lenghu township, where the world-class astronomical observation base takes shape, is hailed as "the most Mars-like place on the Earth." The astronomical observation base was said to be an astronomical observation site comparable to the top ones in the world by a Nature article published on August 18, 2021, according to the Chinese Academy of Sciences. 
Once prospered in 1950s due to its rich petroleum resources, Lenghu is now becoming a premier astronomical observation site and Mars-themed tourist destination, according to Xinhua News Agency.

。今天的任务,称为铱-8,将把最后一颗卫星轨道为铱下一个项目。SpaceX已与铱公司签订合同,为卫星网络发射所有75颗轨道卫星,卫星网络将提供低地球轨道信号覆盖。

三 | 卫星网是对铱原有卫星网的更新换代,铱原有卫星网由1997年至2002年发射的卫星组成。SpaceX定期从加利福尼亚州批量发射10颗新卫星,一次只发射5颗。今天的发射将完成铱网络。大约在发射10分钟后,SpaceX努力确保其猎鹰9号火箭降落在海上的一艘无人飞船上。SpaceX去年12月的最后一次任务是为美国空军发射一颗GPS卫星。由于保密,该公司选择在发射后不回收猎鹰9号火箭。在那次飞行之前,SpaceX的猎鹰9号火箭曾试图降落在佛罗里达海岸,但不幸的是坠入了海洋。幸运的是,今天的火箭恢复非常顺利。

四 | “猎鹰9号”火箭于2018年9月从佛罗里达发射了“电星18号”华帝号卫星,并降落在大西洋的一艘无人飞船上。火箭的成功回收标志着航天公司第33次成功回收猎鹰9号火箭推进器。
