Description

The image is a diagram showing the process of nuclear thermal propulsion. The diagram is divided into three sections, each with a different color. The first section is blue, the second section is orange, and the third section is yellow. The diagram is labeled with the name "Nerva-A" and "Nerva-B" in the top right corner. The diagram features a large circle in the center, which is labeled "Nerva-A" and "Nerva-B." The circle is surrounded by smaller circles, which represent the different stages of the nuclear thermal propulsion process. The diagram also includes a number of arrows, which indicate the flow of energy and materials throughout the process.
