Backup

In space and astronautical engineering, backup refers to a redundant system or component that is available in case the primary system or component fails. Backup systems are critical in space missions to ensure the safety and success of the mission. Backup systems can include redundant power supplies, communication systems, propulsion systems, and life support systems. Backup systems are designed to activate automatically in case of a failure of the primary system. The backup system must be tested and verified to ensure that it is fully functional and can take over in case of a failure. In addition to backup systems, space missions also require backup plans and procedures in case of unexpected events or emergencies.
