Maintenance
Maintenance refers to the set of activities that are performed to keep a space vehicle or a space station in good working condition. These activities include regular inspections, repairs, replacements, and upgrades of various components and systems such as life support systems, power systems, communication systems, propulsion systems, and scientific instruments. Maintenance is crucial for ensuring the safety, reliability, and longevity of space vehicles and space stations, as well as for maximizing their performance and scientific output. Maintenance can be performed by astronauts or by ground-based engineers and technicians, depending on the complexity and urgency of the task. In addition, maintenance procedures and schedules are carefully planned and documented to ensure compliance with safety and quality standards, and to minimize the risk of failures and accidents.
