| Description: |
It turns out that Earth is a pretty good place to live. Finding other habitable environments in space is no easy task: temperatures on Mercury are ten times hotter than on Earth; winter on Neptune lasts about forty years, and Uranus is ten billion miles (sixteen billion kilometers) away.
But there is one planet that looks promising: Mars. Even though it takes six months to get there, Mars most closely resembles Earth. So what would it take to make it habitable—and what would life look like there?
As in the other three titles in the Dr. Dave: Astronaut series, this book demystifies space travel. The science is explained in simple terms while the sense of adventure is ever-present. This book belongs in the hands of every child interested in space, and in every classroom where STEM is taught. |
