Block 1B crew vehicle will use a new, more powerful Exploration Upper Stage (EUS) toadvantages make hybrid rocket motors promising candidates for in-space propulsion. In rocket engines, which are mainly used either to escape Earth’s atmosphere or in-space, there are two broad category of propulsion systems – electric and chemical. The X-57 is NASA’s first all-electric aircraft. The fundamental physical principle involved in rocket propulsion was formulated by Sir Isaac Newton. Rockets designed for interplanetary flight need to supply both a fuel and an oxidant for their propulsion, and the ratio of the two has to be exactly right for maximum propulsion and minimum mass.
