Heat Rejection
Heat Rejection is the process of dissipating excess heat generated by a spacecraft or a satellite during its operation in space. As there is no atmosphere in space, the only way to reject heat is through radiation. The heat generated by the spacecraft's electronic systems, propulsion system, and human occupants (in case of manned missions) must be dissipated to prevent overheating and damage to the spacecraft. The heat rejection system typically consists of radiators, heat pipes, and thermal blankets that are designed to efficiently radiate the excess heat into space. The efficiency of the heat rejection system is critical for the success of the mission as overheating can cause system failures and mission termination.
