5Traveling to space has never been more possible than now. With private companies popping up all over the world, you no longer have to be a NASA astronaut to view the great blue marble from the stars. Of course, scientists and engineers have worked long and hard to create the machines that make this travel possible! In this book, readers encounter some of the cool technology that moves in space, from spaceplanes and rockets, to landers and rovers. Each section describes how one space machine works, complete with clear diagrams to aid visual learners.
