Looking at dark sky at night for a while, you may see a red star. It has dazzling color. People call it “Mars”. In the solar system, beyond the third planet, the fourth one is “Mars”. It is a planet which is far away from Earth, about 2 hundred million kilometers on average. It is so charming that many scientists and people want to go there. Yes, distance lends enchantment to the view.

　　Exploring space is not as easy as you might think. It is beyond your imagination. Scientists still make great contributions to exploring space and they also get good results. Space exploration is developing successfully. Scientists have made great progress with this project in only a few years’ time.

　　In the past fifty years, people have launched many detectors into the unknown universe and planets. However, most of them ended with failure. These detectors still helped the scientists and people to know more about this science. The first time they launched the detectors to Mars was in 1960s. From then on, two super countries, America and the Soviet Union, started a competition to explore Mars. They never stopped launching detectors to Mars. Even if two thirds of them failed. However, it didn’t stop us from exploring space.

　　Distance should not be an obstacle to exploring space. At the beginning of XX. NASA Launched two detectors to Mars, and both of them landed safty. They sent many useful information to Earth. It was really exciting news! Before that, a detector launched by Europe was lost in Universe. It was a shock to the scientific community, but they will never give up.
