Will humans ever be able to live on other planets? Former NASA
astronaut Dr. Dave Williams is the person to ask. 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.
