Evaluation of the Methods for Rescuing EVA (Extravehicular Activities) Crewmembers and Recovering Equipment Detached and Adrift from the Space Station

摘要

This thesis is an analysis of the methods for EVA crew rescue and recovery of equipment detached and adrift from the space station. This top level analysis is aimed at identifying the proper direction to be taken in finding the solution system to the rescue/recovery problems. Results of the analysis indicate that for short range rescue/recovery operations, both an EVA self rescue device and a space station supported device are the preferred solution systems. For medium range rescue/recovery operations, an unmanned free-flyer is the ideal solution system. Finally, for long range operations, the Orbital Maneuvering Vehicle (OMV) is the preferred solution. The analysis also showed that the combination of all these preferred solutions is needed to completely solve the problems. To this end, the analysis provides an example of a comprehensive rescue/recovery system. Finally, the analysis identifies issues and recommends areas which require further analysis in order to fully understand and solve the problems of EVA crew rescue and recovery of equipment detached and adrift from the space station.
