Houston, Texas (June 8. 2002)–in 2004, the National Aeronautics and Space Administration (NASA) will send two robots to separate places of Mars to seek out past or present signs of water. It is an exciting idea to send two robots driving over very different places of Mars at the same time, to be able to see what is on the other side of the hill.

Last month, NASA announced it was sending one robot to Mars, but after two weeks, it decided there was enough money for two. The robots will be sent up within two weeks of each other in May and June of 2003 from Kennedy Space Center. If all goes well, the two spacecraft will touch down on Mars, after a seven-and –a-half-month space flight, on January 2 and 20, 2004.

The robots, each weighing 150 kilograms, can cover 100 meters per day. They are designed to be able to examine the mineral content of the soil, and their special camera will take pictures of the lands and hills. Although they will be under control from the earth, the robots are able to move more freely compared to those sent up before them.

The actual landing points have not been determined yet, but the scientists say it will be in areas where they hope to find water.

49.According to the news report, scientists plan to send robots up to Mars to _____.

A.find out whether there is water on Mars   B.see if robots can find minerals there  

C.test how fast robots can drive there                 D.prove that robots can work on Mars

51. One of the important jobs for the robots on Mars is to _______.

A.study the soil                                     B. walk everywhere
