The Mechanism of Human Error and Defense Strategies of Astronaut Manual Rendezvous and Docking

Astronaut manual rendezvous and docking mission is a complicated systematic project, the astronauts undergo cognitive, decision-making, and implementation stages while on duty. According to the theory of human error, three cognitive stages will be a corresponding error mode. By analyzing the astronaut manual rendezvous and docking mechanism of human error, the current astronaut's errors were classified in manual rendezvous and docking. The barrier levels were analyzed, and multiple human errors' defense strategy of astronaut manual rendezvous and docking was proposed.
