Mars, the red planet
Nasa,the U.S. space agency,announced that humans' first trip to Mars will take place within the next
twenty years.Someday people may live on Mars,called the red planet for its color from space. But before all this
happens,many questions have to be answered.
The most frequently asked question is, Is there or was there ever water on Mars? Water is important because
almost everywhere there is water on Earth, there is life. To discover the possibilities of life on Mars-past
