美航宇局希望在30年代送人前往火星,而在这项任务所需的一系列技术中包括将让当前许多卫星所用系统相形见绌的大型电推进系统。该局格伦研究中心太阳能电推进团队表示现用的太阳能电推进系统功率水平为4千瓦～5千瓦,对位置保持等类工作很有用,但却无法提供在短时间内推动重型有效载荷所需的推力。NASA航天技术任务署眼下正在出资研 NASA hopes to send people to Mars in the 1930s, and a range of technologies required for the mission include large electric propulsion systems that will dwarf the systems used by many of today’s satellites. The council’s Glenn Research Center solar propulsion team said the current solar propulsion system has a power level of 4 to 5 kilowatts and is useful for such things as position keeping but does not provide the power needed to propel heavy payloads in a short period of time Thrust.
