Travel to deep space and back again with The Mars Challenge, a nonfiction graphic novel for teens about the science and logistics of a manned mission to Mars. 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. The challenges are great, but not insurmountable. Humans can reach Mars in our lifetime, and this book explains how it can be done.
