As they plan their Mars mission, students will use the same navigation method that NASA uses for interplanetary travel - the Hohmann Transfer Orbit. You can use this STEM activity, and the included Rover's slideshow to introduce a Solar System unit or a Mars rover design project. In addition to plann
