Scientific paper

A concept for an hybrid nuclear-laser rocket engine is described. The use of a solar-pumped laser is proposed to resolve temperature limitations in the combustion chamber. The propulsive mass, normally heated in the active zone to 1000-2500 K, can be ultimately heated by laser energy to 20,000-30000 K, increasing the exhaust velocity of the propulsive mass. This would lead to a significant reduction in fuel mass requirement. A scenario for application of the system in Earth-Mars flight is described.
