Abstract

The various measures applied for reducing launch cost, by introducing ultralightweight and reliable structures and payloads in space explorations, are discussed. For the viability of a sustained human presence in space, launch cost is a critical factor. It is expected that the development of off planet infrastructure will be driven by launch dollars per kilogram. The genesis of cost model is the observation that the operating cost of high power system is not dictated by delivered energy but by peak system power. It is feasible to develop a heavy lift mach 0.8 platform at low cost, largely based on modifications to existing aircraft. It is also noted that with savings of as much as $4000/kg, a $5 billion development could be paid for in 12 launches at 100t each. The results show that the most significant cost for Earth-launch boosters is a peak thrust power and that the launch cost and peak power may be linearly related.
