Remaining Useful Life

Remaining Useful Life (RUL) is a concept used in space and astronautical engineering to estimate the remaining operational time of a spacecraft or its components before they become unusable or require maintenance. RUL is calculated based on various factors such as the age of the spacecraft, its usage history, environmental conditions, and the performance of its components. By estimating RUL, engineers can plan for maintenance and replacement of components before they fail, reducing the risk of mission failure and increasing the overall reliability of the spacecraft. RUL estimation is typically done using statistical models and machine learning algorithms that analyze data from sensors and other sources to predict the future behavior of the spacecraft or its components.
