Satellites today are launched via booster rocket from a limited number of ground facilities, which can involve a month or longer of preparation for a small payload and significant cost for each mission. Launch costs are driven in part today by fixed site infrastructure, integration, checkout and flight rules. Fixed launch sites can be rendered idle by something as innocuous as rain, and they also limit the direction and timing of orbits satellites can achieve.
Based on current quantum mechanical models, the energy density of the quantum vacuum is predicted to be high. Recent advances in fabricating material nanostructures and cavities have fueled the study of vacuum fluctuation-driven phenomena, indicating that the energy density can be modified locally.
