Thermal control is a means of managing the level of temperature of equipment, payloads, satellites and launchers is essential during all phases of a space mission to protect flight hardware and to guarantee the optimum performance and success of the mission.

Since thermal control is the measure taking to maintain the spacecraft’s temperatures within set parameters during its lifetime. The thermal subsystem needs to be properly designed and tested and need to be very efficient and highly reliable. Thermal control is also what keeps the specified temperature stability for delicate electronics or optical components so as to ensure that they perform as efficiently as possible.

Thermal control for space applications covers a very wide temperature range, from the cryogenic level (down to -270 deg C) to high-temperature thermal protection systems (more than 2000 deg C). The thermal control subsystem is one of the most visually distinctive elements of a space system, composed of distinctive foil-like insulation blankets and white-painted or mirror-like radiators.
Structures and Mechanisms involves all activities connected to the launcher and satellite structure and the moving parts associated with it. The structure provides a strong supporting framework to house payloads, instruments and satellite subsystems, especially through the stresses of launch.

Moving mechanisms attached to the rigid structure are crucial to mission success. They include motors, reaction wheels and deployment systems for folded-down antennas or solar arrays. Other examples include sensor pointing and scanning mechanisms, gravity-detecting gradiometers and valve and turbo pump components for propellant systems.
Propulsion covers all methods of propelling launchers and space vehicles, including chemical, electric and advanced systems. Aerodynamics is the study of how high-velocity gases behave, employed as a tool for optimizing engine design and also to model the process of atmospheric ascent and re-entry.

Therefore the sphere these aforemention activities is what puts the spacecraft in space, encapsulating launcher and spacecraft propulsion technologies as well as atmospheric ascent and re-entry.
