Welcome to the Ion Propulsion module. Learners of all ages explore the propulsion technology that that made the Dawn mission possible. The feat of engaging in extended orbits investigating two different destinations in the main asteroid was a NASA first! As learners engage with this module—reading, exploring playing! —they will gain an understanding of:

  • Charges and relative charge
  • Momentum and frames of reference
  • Ionization and plasma
  • How an ion propulsion system works

Finally, they will Experiment with designing an ion engine to determine optimal conditions using an interactive simulation
