Minear, UK Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory...For scientists there is another reason. Their observations and research will probably lead to great scientific achievements. Donal Trollop, Canada There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地 )on Mars. It will happen when people finally realize that two way trips to the red pla Mars are unnecessary. Most of the danger of space flight is in the launches(發(fā)射 ) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world. Enough supplies can be sent on ahead. And every two years more supplies and more people will be sent to the new colony. Mars has all the materials for a colony to produce or make everything it needs, and Mars is far more pleasant than the other plas in the outer space.
