The scientific objectives of the M3 STEP mission are threefold. Firstly, and most importantly, the aim is to test the equivalence principle (EP) to one part in 1017, following the beautifully elegant STEP method conceived originally some 25 years ago by P Worden and C W F Everitt. It is noteworthy that over this period of time the detailed design of the experiment has matured considerably.
