Massively Expanded NEA Accessibility via Microwave-Sintered Aerobrakes

The availability of a wide range of natural resources among the near-Earth asteroid (NEA) population offers the opportunity to utilize these resources in the service of making access to most of the Solar System much easier than any classical approach which relies solely upon structural, heat-shield, life support and propellant materials lifted from Earth.We have concentrated our attention on the two main factors that influence the application and utility of in situ aerobrake manufacture on near-earth asteroids. The first of these is the use of microwave sintering in the fabrication of aerocapture heatshields for retrieval of asteroidal materials into Earth orbit; the second is assessment of the performance of these aerocapture devices, including making very large numbers of NEAs accessible as sources of essential materials to support space exploration and exploitation.

Microwave heating of lunar materials. Appendix A

Microwave heating of nonmetallic inorganic material has been of interest for many years. Von Hippel in the late 1940's and early 1950's investigated how microwave radiation up to 10 GHz couples to various insulator materials. Perhaps the most work has been done by Wayne Tinga at the University of Edmonton. Most of the work to date has been done at the two frequency bands allowed in industrial use (0.915 GHz and 2.45 GHz). However some work has recently been carried out at 28 GHz and 60 GHz. Work done in this area at Los Alamos National Laboratory is discussed.
