Why do astronauts feel heavy after take-off? Why are rockets long and
thin? How do spacecraft orbit Earth? Covering lots of different aspects
of space exploration, including looking at how spacecraft such as rocket
launchers, satellites and space stations work and more human questions
such as why astronauts need to keep so physically fit and what kit they
need in their spacesuits, Fly to Mars! takes a fun look at forces in
space. While learning about forces you will find that you also find out
the answers to many questions that you have asked yourself about
astronauts and space, and more. This Feel the Force series shows how
forces and motion work in the world around us, in a set of high-interest
situations. Each book includes three simple activities or investigations
for readers to try. Overlays over large photos, plus diagrams, show how
forces are acting in a given situation. Topics covered in the series
include basic pushes, pulls and friction, air resistance, gravity, mass,
weight and springs.
