Human Information Flow and Communication Pattern in NASA Mission Control System

Abstract

This study is a preliminary effort to explore human information flow and communication pattern in an operation-critical and time-constrained collaboration environment such as NASA Mission Control System. Understanding information flow and communication pattern is a key step for improving the reliability and accuracy of a complex Human-Machine system. It also can be applied to design a better communication system for future NASA Mission Control Center operations. The information flow and communication pattern analysis based on NASA mission control training simulations indicates that there is no significant utilization difference among communication channels, however, the communication channel's burst rate is significantly affected by phase, mission and channel type.
