美国航宇局正加紧在月球上建立美国基地或载人飞行到火星的研究工作,以获得新政府的支持。在1991年美国航宇局正式提交月球基地和火星飞行任务的建议之前,要在1989—1990年期间把它们最初的研究结果提交给布什总统。目前,布什赞成在从事火星飞行计划之前先建立美国月球基地。美国航宇局正在加紧月球基地空间商业化方面的评估工作。但是一套全新的设计思想也正被人们关注,即发射美国宇航员到火星卫星 NASA is stepping up its research efforts to establish a U.S. base on the moon or manned flights to Mars in order to gain the support of the new government. Pending the formal submission of NASA’s proposals for a lunar base and Mars mission in 1991, the initial findings of their study were submitted to President Bush during the period 1989-1990. At present, Bush is in favor of establishing a U.S. moon base before embarking on a Mars flight plan. NASA is stepping up its assessment of the commercialization of the lunar base. But a new set of design ideas is also being concerned about the launch of the US astronaut to Mars satellite
