The Breakthrough Propulsion Physics project (BPP) was a small NASA research effort, run from 1996 to 2002, to study speculative ideas for spacecraft propulsion that would require discoveries in physics, such as propellant-free "space drives" and faster-than-light travel. It is often cited in discussions of how UFOs might move.[1][2]

Managed by NASA engineer Marc Millis, the project aimed to make "incremental and affordable" progress toward propulsion without propellant, travel at the fastest possible speeds, and new ways of powering such devices. Over six years it received about $1.2 million, funding five external research projects, two in-house tasks and one small grant.[1]

Findings

Millis summarised the results on 14 topics:[1][3] - Six ideas were found not to work, including an "antenna" thruster that produced no thrust, Eugene Podkletnov's claimed gravity-shielding effect, which could not be confirmed, gyroscopic "antigravity" devices and the idea that quantum tunnelling could carry signals faster than light. - Four, including the Casimir effect and the role of the vacuum, were judged worth further research. - Four were left unresolved, including James Woodward's proposed "transient inertia" or Mach effect, whose small predicted force had not been confirmed.

The project also examined seven hypothetical space drives, including the Alcubierre "warp drive", and studied zero-point energy, concluding that any forces from the quantum vacuum would be extremely small.[1]

End and legacy

NASA cancelled the project in 2002 when it reorganised its advanced propulsion research and dropped work at the earliest stages of technology readiness. Millis and others went on to found the Tau Zero Foundation, and NASA supported Millis in documenting the results, published by the American Institute of Aeronautics and Astronautics in 2009 as Frontiers of Propulsion Science.[1][2]
