Does anybody know why "STEP" mission was canceled, and if any similar one is planned for next years?

STEP will advance the testing of the Equivalence Principle from several parts in 1013 to 1 part in 1018. Whether it confirms Equivalence five to six orders of magnitude more precisely than known today or discovers a violation, it will be a landmark experiment in Fundamental Physics, with consequences extending from gravitation theory to cosmology to theories of the evolution of the Universe. It will probe a large and otherwise inaccessible domain in the parameter space of new interactions. A null result would remain for many years a severe constraint on new theories. A positive result would constitute the discovery of a new force of Nature.
