AAWSAP DIRD: Negative Mass Propulsion, January 3, 2011 — Department of War Research Paper

Las Vegas, Nevada

This DIRD examines whether negative mass could exist in a physically meaningful way and whether it could someday reduce the energy cost of spaceflight. The report reviews the unusual dynamics that would follow if positive and negative mass could interact, including self-accelerating mass pairs…

AAWSAP DIRD: Quantum Tomography of Negative Energy States in the Vacuum, January 11, 2011 — Department of War Research Paper

Las Vegas, Nevada

This DIRD examines how negative-energy, or “sub-vacuum,” states in quantum fields might be detected and mapped. Its practical scope is limited to the laboratory-scale measurement of minute quantum effects, though it extrapolates from those effects to consider theoretical relevance to concepts…
Illustrations of engineering concepts designed to withstand large energy differentials within a theoretical nuclear explosion-powered propulsion system for deep-space travel.

AAWSAP DIRD: Advanced Nuclear Propulsion for Manned Deep Space Missions, March 11, 2010 — Department of War Research Paper

Las Vegas, Nevada

This DIRD examines advanced nuclear propulsion for crewed deep-space travel and argues that human missions beyond the Moon would require propulsion systems with both very high thrust and very high specific impulse, which the author contends are difficult to achieve with conventional chemical,…

AAWSAP DIRD: Advanced Space Propulsion Based on Vacuum (Spacetime Metric) Engineering, March 29, 2010 — Department of War Research Paper

Las Vegas, Nevada

This DIRD examines the idea of vacuum or spacetime-metric engineering: the possibility that an unspecified future technology might alter the structure of spacetime in ways useful for propulsion, power generation, or extremely rapid long-distance travel. Using general relativity as a…
A statistical treatment of the Drake thought framework for estimating the number and proximity of communicative extraterrestrial civilizations.

AAWSAP DIRD: An Introduction to the Statistical Drake Equation, March 11, 2010 — Department of War Research Paper

Las Vegas, Nevada

This DIRD introduces the Drake Equation, a well-known thought framework for estimating how many communicative extraterrestrial civilizations might exist in the galaxy. It reformulates the equation in statistical terms, arguing that the usual approach of assigning fixed values to its variables is…
Diagram shows a simplified design for nuclear fission-propelled rocket.

AAWSAP DIRD: Aneutronic Fusion Propulsion I, November 1, 2010 — Department of War Research Paper

Las Vegas, Nevada

This DIRD surveys aneutronic fusion as a possible advanced space-propulsion method, focusing on fusion reactions that release most of their energy in charged particles rather than neutrons and therefore offer potential advantages over more neutron-intensive fusion concepts, especially in…
