据《航空航天技术周刊》2015年9月7日报道,NASA再次评估了利用核热动力火箭(NTR)执行深空任务的可能性。比起效能最高的化学燃料火箭,核热动力火箭具有更强大的推力,并增加了1倍的比冲,能够节省大量任务时间和成本。核热动力火箭概念:火箭发动机以核裂变反应堆为基础,加热液氢推进剂,而不是燃烧化学可燃推进剂。NASA正在为火星探索及更远的深空任务研发渐进式系统架构,这种大推力推进系
According to the Aerospace Technology Weekly report on September 7, 2015, NASA reevaluated the possibility of using the nuclear thermal power rocket (NTR) to perform deep space missions. Compared to the most efficient chemical fuel rockets, nuclear thermal rockets have stronger thrusts and a 1-fold increase in specific impulse, saving a lot of time and money on mission time. Nuclear Thermal Power Rocket Concept: Rocket engines based on nuclear fission reactors heat liquid hydrogen propellants instead of burning chemical flammable propellants. NASA is developing a progressive system architecture for Mars exploration and further deep space missions. This large thrust propulsion system
