| description abstract | Abstract: From the analyses performed after the Mars Observer mission failure, it became apparent that the MO fault protection suffered from a lack of top-down system engineering design approach. Most fault protection was in the category of low-level redundancy management. It was also determined that the MO fault protection software was never tested on the flight spacecraft before launch. Design fault protection to detect and respond to excessive attitude control errors, use RCS Thrusters to control excessive attitude control errors, and always test fault protection software on the flight spacecraft before launch. | |
