Houston, Texas (June 8, 2002)-In 2004, the National Aeronautics and Space Administration (NASA)
will send two robots (机器人) to separate places of Mars to seek out past or present signs of water. It is
all 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 (宇宙飞船) will touch down on Mars,after a
seven-and-a-half-month space flight,on January 2 and 2O, 2OO4 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 Earth,
the robot, 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.
