What is the service module?

The service module is a unit in a spacecraft or space station that is completely separate. The module may include avionics and equipment, drive systems, living rooms and delivery. Such units can be able to start and reentry so that their space agencies allow reuse and can be configured in different ways. Many nations have created service modules for use on spacecraft and projects such as International Space Station (ISS). Designers develop separate content protection systems, including life support for service modules used to place staff or projects that require astronauts inside, as scientific laboratories. During the start, it must be able to take considerable strength and, in the case of reentry equipment, must also have systems to support safe return to Earth.

At the International Space Station, the service of building a orbiting research facility was used by modules supplied by the participating nations. Modular Design UmoHe drowned the construction of a growing structure rather than limiting the development to a single start. Service modules added to ISS may include features that allow them to reconfigure for new components in the future. They can also be used for different activities. For example, the bay of the cargo can be converted to the laboratory if it has been designed for multiple configurations.

There may be one or many partitions with different features within the service module. Some are designed exclusively for cargo transport and can be very large to suit large objects. Others contain life support systems, drive and controls and correspond to other modules to support a spacecraft or space station. In modules designed for astronauts can be command centers, living quarters and eating equipment, experiments, etc.

Weight is an important aspect in the design of the service module. Sending everything to space is inElmi costly and designers want to make sure that every pound is calculated. Excessive weight in structures can be eliminated in different ways and the interior space can be designed for multi -purpose and configuration to make it more useful. The service module with limited applications may be too expensive to the market and maintain, as the payment of use does not have to balance the cost of designing, building and starting.
