MMS T-Book Pre Survey
You are about to launch into an investigation of magnetism and learn about the MMS Mission. We'd like to know what you already know. This will let us see how much you learned. Don't worry if you don't know the answers to the questions. Just do the best you can. Then when you do the post survey you'll know everything!
