The planet Mars has very little oxygen and water;the temperature at night is below-50℃and winds of 100miles per hour cause severe dust storms.However,the surface of the planet seems to show that water flowed across it at some time in the past,and it is believed that there is enough ice at the poles to cover the planet with water with water if it melted.
Questions:Is there any life on Mars now? Was there ever life Mars? Or will there be any life on Mars? Explain your answer.
解答:
谁问的问题啊？科学家都不知道上面有没有生命。
英文回答（我的见解而已）
There has been no scientific proof for life on mars either now or in the past. NASA’s Phoenix Mars Mission has landed on Mars for more than 100 days but finds no proof for any kind of life form. However, nothing is for certain in the world of science, who are we to define beyond our understanding？
中文翻译：
到现在为止，还没有任何科学依据证明火星上有任何生命。 美国航空航天局的Phoenix Mars Mission （中文的翻译我不清楚）已经在火星上进行了100多天（到今天为止是109天），但是仍然没有发现有任何生命的迹象。但是，在科学的领域中是没有绝对的，我们怎么可能定义还不了解的事物？
要是真的对火星感兴趣，参考资料就是NASA的 Phoenix Mars Mission的主页。看看吧。
