This Defense Intelligence Reference Document, prepared by the Defense Intelligence Agency and dated 8 March 2010, was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It gives a historical and technical review of how to reach space and return. It covers hypersonic gliders, air-breathing and rocket propulsion, thermodynamics and materials, and launch options. It argues that reliable, schedulable access to low Earth orbit is mainly a hardware and propulsion problem rather than a technology one.

was contained within CONUS, demonstrating a significant maneuver capability. If a
glider carries a fuel reserve, it can be reaccelerated to a recoverable-range glide speed.

But where is our space infrastructure? Forty years after Apollo, why have we advanced
so little (as illustrated in Figure 43)? Like the pioneers' Conestoga wagons, most of our
trips to LEO are one way, and when we do return, we do so with little more than the
people we took to space. There is no evidence that any Conestoga wagons ever
returned to St. Louis or St. Joseph, Missouri, from which most departed; rather, most
were used as building materials on the West coast.
