This Defense Intelligence Reference Document from the Defense Intelligence Agency is dated 3 January 2011. It was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program as part of a series of advanced technology reports. The report asks whether negative mass exists and whether it could be used for propulsion. It concludes that one route might be an ultra-light form of matter that could have gathered at the Moon's center. Reaching it would take a tunnel dug with thermonuclear shape charges.

Both the pressure and the temperature are technically manageable, the pressure with layers of shattered rocks around a tunnel passing through the center of the moon, and the temperature with some cooling. Seismic measurements suggest that the center of the moon is made up of hot rocks. If appreciable amounts of negative matter have accumulated over billions of years in the center of the moon, it is more likely that this matter is in the form of ultra-light matter, perhaps by an order of magnitude lighter than ordinary matter. There are indications that a Swedish research group has found evidence for the existence of an ultra-dense phase of deuterium, about more than 100,000 times more dense than water [16]. Suppose that in the center of the moon the accumulation of negative matter has led to a form of matter which is 100,000 times lighter than steel, but still has the strength of steel. This would not lead to a negative-positive mass self-chasing mass dipole as envisioned by Forward [ 13], but to something very important for space- flight, because it would dramatically reduce the energy requirements to accelerate a space era~ made from such ultra-light material. The question as to whether there is such an unusual substance in the center of the moon can probably be answered by seismic wave tomography, obtained by nuclear explosions set off on the surface of the moon. 12. Making a Tunnel through the Moon [15] The cohesive energy of rocks is of the order &r ~ 1010 erg!cnT'. Therefore, the explosive yield needed to shatter a spherical volume of radius r is (108) The energy released in a kiloton nuclear explosion is E,:::; 4x 1019 erg. With this energy, the radius of the crushed rocks would be r:=:d0 3cm(= 10 m), and with a 10 kiloton explosion it would be twice as large. 33 UNCLASSIFIED//FlilA. lilFFUilil:lo lal!i! 811Llf
