苏联“东方二号”和“东方四号”宇宙飞船的联合編队航行和凱旋归来,标志着人类飞行到其他星球的日子,愈来愈近了。人类向別的星球进軍是为了什么呢?自然不仅仅是为了滿足好奇心。征服宇宙的問題之所以成为现代科学的前沿陣地,实在是因为科学发展到現阶段,許多問題在地球上已經无法解决了,必須使用各种各样的科学仪器和設备,超出地球大气层去进行研究和观察。
The joint formation sailing and triumphant return of the Soviet “East II” and “Oriental IV” spacecraft mark the days of human flight to other planets and are getting closer. What does it mean for human beings to march into other planets? It is not just natural curiosity to satisfy. The reason why the issue of conquering the universe has become the frontier of modern science is really because the scientific development has reached the present stage. Many problems have not been solved on Earth and all kinds of scientific instruments and equipment must be used to go beyond the Earth’s atmosphere Research and observation.
