Whether we can land on (登陆)the Mars depends entirely on (is up to )(取决于 )the development of science and technology.Man have got some realization about it.It is a place without oxygen .What is worse,it might be fifty degree aroud at midday while it might fall down to one hundred degree below zero.Thus,it is impossible for us to live there. Since the earth and the Mars are totally different,we should prepare enough food,clothes and the oxygen bottle as well to visit the Mars one day(有朝一日).However,it is no doubt that(certain that),man can land on it sooner or later (迟早)

If our can land Mars depends on development of science and technology completely. Human being has had a few .know about to Mars: But do not have oxygen on Mars , may in Mars last noon temperature in 50 degree or so, evening is 100 degree or so in the subzero. Like this, we live Jiu Bu Neng in there. Since Mars and the earth are totally different, if our plan goes to Mars if one day ,we will have oxygen , food and clothes at hand. But can be sure that human being will be Martian Deng Shang sooner or later.

Whether we can load on Mars definitely counts on the development of the science and technology.We human beings know a few of Mars: no oxygen , temperature there may be about 50 degree at noon and 100 degree below zero at night. Therefore, conditions are not allowed for us to live there.Since Mars and the earth differ, we have to bring oxygen ,food and clothes if we are planning to go to Mars one day. Still,one thing that can be sure is that we will load there ,sooner or later.
