2月14日欧空局的“阿里安”5火箭完成了VA-235发射任务,这种20世纪80年代开始设计、1996年首次发射的运载火箭已经走过了20年的岁月。虽然它仍是国际商业发射市场的主力之一,但很多方面已开始有些落后。欧空局正在研制新一代的“阿里安”6火箭,它将使用新的火神2.1和芬奇氢氧发动机,通过组合化设计满足未来的发射需求并大幅度降低成本,而在重复使用方面,欧空局将研
On 14 February, ESA’s’’Arian “5 rocket completed its VA-235 launch mission, which began its design in the 1980s and landed for the first time in 1996 after 20 years. Although it is still one of the main forces in the international commercial launch market, it has started to lag behind in many aspects. ESA is developing a new generation of ”Arian" 6 rockets that will use the new Vulcan 2.1 and Vinci Hydrogen Oxygen engines to meet future launch requirements and significantly reduce costs through a combined design, For use, ESA will research
