Is There Life on Mars?
Advancements in space exploration over the years have shown us that Mars does not have alien beings living on its surface, as it does in movies and books. Mars is on the edge of the solar system's habitable zone. It has water, one of the necessary conditions for life as we know it, though only in the form of ice. Scientists believe that Mars had liquid water in the past and so they continue to look for signs of life. Readers will find out what life on Mars would be like, see vivid photographs, and learn the details of upcoming NASA missions.
