今年6月22日,美国航宇局宣称,他们从“火星环球勘测者”探测器拍摄的照片中,发现火星上有水的确切证据。至此,载人火星飞行似乎已呼之欲出了。那么,应如何准备载人火星飞行呢?我们中国人有一句俗话,叫“穷家富路”,那是说,不管家中如何穷,外出时要带足路途上所需的各种物品,应尽可能富裕一些。 载人火星飞行是一项很复杂的技术工程,如要有可靠的大型运载火箭、技术先进的载人飞船,要选择合适的飞行路线,要解 On June 22 this year, NASA announced that they had found the exact evidence that there was water on Mars from photos taken by the Mars Global Surveyor. At this point, the manned Mars flight seems ready to come out. So, how should we prepare for the flight of the manned Mars? We Chinese have a common saying, “poor family rich road”, that is to say, no matter how poor at home, go out with a variety of items necessary to take the foot on the road should be As wealthier as possible. Manned Mars flight is a very complex technical project, if there is a reliable large launch vehicle, technologically advanced manned spacecraft, to choose the appropriate flight route, to be solved
