How do you start? Assume the audience is technically competent, but isn't familiar with your project? What do they need to know first?

1. Constant Power and Thrust: Prescribed Mission Time Starting with a mass M0 , and operating for a time t an electric thruster of jet speed c, such as to accomplish an equivalent (force-free) velocity change of ∆V , the final
