Solar Thermal Propulsion Systems
Solar Thermal Propulsion Systems are a type of rocket propulsion system that uses the energy from the sun to heat a propellant, typically hydrogen, to extremely high temperatures, creating a high-velocity exhaust that propels the spacecraft forward. The system consists of a parabolic mirror or a series of mirrors that concentrate sunlight onto a heat exchanger, which then heats the propellant. This type of propulsion system has the potential to provide a high specific impulse, which means it can achieve a high velocity with a relatively small amount of propellant. However, it also has some challenges, such as the need for a large and heavy mirror system and the difficulty of maintaining the high temperatures required for efficient operation.
