# Getting There!: Navigation and Trajectory

### Source Institutions

NASA

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement. In activity two, learners working in pairs plot the paths (trajectories) of a spacecraft traveling between Earth and Mars in the year 2018 and returning in 2020, while using the minimum amount of fuel. This lesson guide includes background information, suggested questions, answer keys, and handouts.
