火星探测的主要科学问题

Major scientific issues involved in Mars exploration

在太阳系的行星中,火星与地球之间存在最多的相似之处,因此,火星是一颗承载人类最多梦想的星球。火星有水和生命存在的问题,激发了人类火星探索的好奇心,成为人类持续探测火星的推动力。火星的起源和演化与太阳系形成过程的关系,火星与类地行星的共性和特性,是当代行星科学研究的重要内容。为了人类社会的可持续发展,火星可否改造成为适宜人类居住的绿色星球——这些是人类在火星探测中必须面对的重大科学问题。只有这些重大科学问题被一一解答,我们才能清晰地去思考地球和人类自身的未来!

Among the planets of the solar system discovered so far,the similar features between the Mars and the Earth is the most prominent.Therefore,the Mars takes an important place in human＇s dreams.The issue about Mars water and life inspires the curiosity of exploring the Mars,and becomes a drive of successive Mars explorations.How did the Mars evolve and what is behind this evolution？ What is the relationship between the evolutions of the Mars and the solar system？ Can we make the Mars a green planet fit for sustainable human habitation and development？ One must unveil these major scientific issues in the course of their Mars explorations.Only after these issues are solved one by one can we go on to think about the future of the Earth and mankind as related with the Mars.
