Solar Assisted Reusable Rocket System
Abstract
The growing demand for cost‑effective and environmentally sustainable space transportation has encouraged the development of reusable rocket systems and renewable propellant technologies. This paper proposes a solar assisted reusable rocket system capable of producing its own propellant using renewable energy. Solar panels generate electricity that powers the electrolysis of water to produce hydrogen and oxygen. Hydrogen can be used directly as rocket fuel or converted into methane through a methanation process, while oxygen serves as the oxidizer. The generated propellants are stored in cryogenic tanks and used in the rocket engine for combustion to produce thrust. The reusable rocket design enables recovery and multiple launches, significantly reducing operational costs and environmental impact.
