Nadia is a teenager with a dream: to be the first woman on Mars. But there are a lot of obstacles in her way: gravity wells, interplanetary trajectories, space weather, and that pesky rocket equation. It's a good thing Nadia's friend Eleanor is a space wiz. Eleanor explains how scientists are working to overcome the numerous challenges involved in a manned mission to Mars. Eye-catching illustrations and detailed diagrams bring to light the scientific concepts and complex machinery of interplanetary travel. The challenges are great, but not insurmountable. Humans can reach Mars in our lifetime, and this book explains how it can be done.
