Inertial Mass Modification and Reactionless Propulsion
Preserves the original positive report so the claimed effect can be compared with later controls and replication.
Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum
Documents the Eagleworks EM Drive vacuum thrust claim that later metrology attempted to reproduce.
A positive experimental report is evidence that a signal was reported, not that momentum conservation was violated.

Stable NASA technical-report destination. No PDF page locator is published here unless independently verified.Tests whether a reported effect survives a different apparatus, laboratory, or analysis.
High-accuracy thrust measurements of the EMDrive and elimination of false-positive effects
High-sensitivity follow-up focused on thermal, magnetic and balance artifacts in EM Drive measurements.
Constrains this experimental architecture; it does not logically exclude every conceivable propellantless mechanism.

Prospects for Breakthrough Propulsion From Physics
NASA technical review separating measurable research questions from speculative propulsion goals.
A research-program assessment is not experimental validation of any specific breakthrough drive.
