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.
