  Many scientists are now exploring the idea of going to live on Mars. Some other scientists from the NASA Ames Research Centre(美国航空航天局艾姆斯研究中心) have already started the creation of a "Mars town" and many others are in fact already experimenting with it. Of course, these experiments are done on Earth itself but this " Mars town" has an environment practically like that of Mars.

  The astronauts working in these towns wear their spacesuits and also do everything they would really have to carry out if they ever go to Mars in the future.

  But Mars would be like Earth,a temporary place for humans. When the Sun starts swallowing up the planets,Mars will disappear only hours after Earth. So Mars only seems to be the ideal place to spread the human beings. It is also a good location to send humans if ever there is a disaster on Earth. By saying disaster,I mean asteroids(小行星) hitting and things like that.

  If we humans do not want to disappear when Earth or Mars gets swal?lowed up,we will have to go and live beyond the solar system. But are there any planets outside our solar system prepared to support life? Astronomers' answer is:

  "If Earth can support life,why can't other planets do the same too? As?tronomers have already discovered a Jupiter(木星) -like planet orbiting a Sun?like star,so why not an Earth-like planet orbiting a Sun-like star?"

  To achieve this goal though，many other problems have to be taken into con?sideration. How do we transform a dusty planet like Mars into one more or less like our Earth? How should we go on? There is still a long way to go.

   D.there's no need for humans to move beyond the solar system
