On the Economic Viability of Reusable Space-Rocket Systems Use to Deliver Payloads to Satellite Orbit

One of the important tasks of space exploration is the delivery of cargo for various purposes to low Earth orbits (further—SO: satellite orbit). Traditionally, such tasks were solved with the help of disposable carrier rockets and used to bring payloads (including manned spacecraft) into these orbits. The problems of economic viability evaluation to define the expediency of use of reusable space-rocket systems for the payload delivery to satellite orbit are considered. The examples of reusable space-rockets systems for delivering payloads to satellite orbit are given. The method of determining the economic efficiency of reusable space-rocket systems is considered. This method allows evaluating the advantages of each of reusable space-rockets systems under consideration and to determine the possibilities for their effective application. The results of the cost estimation per 1 kg payload delivery for various types of launchers including reusable space-rocket systems are given.
