人到月球去旅行巳经不是太遥远的事了。据学者们估计,在十年内甚至五年内,这一伟大理想就可能成为现实。两条道路通向月球有直接的和间接的两条可能的道路。直接的道路是用强大的多级火箭,把载人宇宙飞船直接发射到月球上去;在完成科学任务后,再直接从月球飞回地球。 It is not too far away when people go to the moon to travel. According to scholars’ estimates, this great ideal may become a reality within ten years or even five years. There are two possible paths, two direct and indirect, that lead to the moon. The direct path is to launch a manned spacecraft directly to the moon with a powerful multi-stage rocket; after completing the scientific mission, it will fly directly back to Earth from the moon.
