Nuclear Energy
Nuclear energy is the energy released from the nucleus of an atom through either nuclear fusion or nuclear fission reactions. In astronautical engineering, nuclear energy is used to power spacecraft and satellites. Nuclear reactors are used to generate electricity on Earth, but in space, they are used to provide power for long-duration missions. Nuclear energy is a highly concentrated source of energy, which makes it ideal for space missions where weight and space are at a premium. However, the use of nuclear energy in space also presents unique challenges, such as the need to protect the crew and the environment from radiation.
