2017年3月,据新华社报道,在小行星探索作为登陆火星“跳板”的方案遇阻后,美国航天局又提出在月球轨道上打造太空港作为“深空门户”的新计划,以实现送人往返火星。这个太空港建设完成后将由一个小型居住舱、气压过渡舱、大功率电力推进系统以及一个可开展研究的后勤舱组成,并具备对接能力,从而作为通往月球表面和深空目的地的门户。本质上,这个月球轨道太空港将类似一个小型国际空间站,但里面不会有人常驻,且能升降轨道,
In March 2017, according to the Xinhua News Agency, NASA proposed to build a spaceport on the lunar orbit as a new “astronomical” portal after the exploration of asteroids as a landing “Marshal” Plan to send and leave Mars. Upon completion, the spaceport will consist of a small dwelling unit, a pneumatic transitional chamber, a high-power electric propulsion system and a studyable logistics capsule with docking capabilities to serve as a gateway to the lunar surface and deep space destinations. In essence, this lunar orbit spaceport will resemble a small ISS, but there will be no permanent presence and will be able to lift orbit,
