Description

The image is a diagram showing the different stages of a nuclear thermal propulsion system. The diagram is divided into three main sections, each representing a stage in the process. The first section is labeled "Nuclear Reactor," which is the initial stage of the system. The second section is labeled "Neutron-Induced Fission," which is the stage where the nuclear reactor produces energy through the fission of atomic nuclei. The third section is labeled "Nuclear Thermal Propulsion," which is the stage where the energy produced is used to propel a spacecraft. The diagram also includes several labels and arrows, providing additional information and clarification about the different stages of the nuclear thermal propulsion system.
