Breakthrough Propulsion Physics Program (BPPP)
The Breakthrough Propulsion Physics Program (BPPP) was a small program, managed by the Glenn Research Center and sponsored jointly by the Advanced Space Transportation Program and Advanced Concepts Program, to study fundamentally new forms of propulsion that would involve no propellant mass and, if possible, faster-than-light travel. NASA's funding for this program has now ceased.
