一 | Jet engine maker Rolls-Royce said Tuesday it's cutting up to 2,500 jobs globally as part of a corporate overhaul that its new CEO is carrying out. The aerospace company was hit hard by the COVID-19 pandemic that decimated demand for air travel. Tufan Erginbilgic, who took over as chief executive in January, said the layoffs are aimed at making Rolls-Royce “more streamlined and efficient." Rolls-Royce, based in Derby, central England, didn't disclose where jobs will be cut, but around half of its 42,000-person workforce is based in the United Kingdom.The cuts will remove duplication and bring cost efficiencies in the latest stage of its “multi-year transformation," the company said. “We are building a Rolls-Royce that is fit for the future," Erginbilgic said. The company slashed 9,000 jobs globally in 2020 as it grappled with the collapse of air travel during the pandemic.The new turnaround plan also includes creating a new company-wide procurement division that can take advantage of Rolls-Royce's size to cut costs and reduce supply chain delays.。
二 | 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。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。
四 | 幸运的是，今天的火箭恢复非常顺利。“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。
