自古以來,人们就在幻想着,飛出地球,到别的星球上去,特别是到离我们最近的月球上去。不过,在过去,由於科学技術的發展水平不够,人们祇能把宇宙航行寄託在一些美麗的幻想故事中。我國民間流傳的嫦娥奔月、唐明皇遊月宮等神话,就是这样的幻想故事。祇有到了现代,由於人類社会的經济与文化的巨大發展,特别是由於人類对宇宙有了科学的理解和火箭技術的突飛猛進,宇宙航行才由幻想变为现实。科学家和工程師們的研究証明,星际交通是完全可能的,並且在不久的将來就会实现。全世界億万人民都在注视着星际交通的科学研究進 Since ancient times, people are fantasizing, flying out of the earth, going up to other planets, especially to the moon nearest us. However, in the past, due to the insufficient level of development of science and technology, people can only pin their cosmic voyage in some beautiful fantasy stories. Myths such as the legend of Chang’e flying to the moon and the Tang emperor tour of the moon in our folklore are such fantasy stories. Only in the modern era have the cosmic voyage become a reality from fantasy due to the tremendous economic and cultural development of human society and, in particular, the scientific understanding of the universe and the rapid advance of rocket technology. Research by scientists and engineers has proved that interstellar traffic is entirely possible and will be achieved in the near future. Hundreds of millions of people all over the world are watching the progress of scientific research in interstellar transport
