Abstract: Astronauts often encounter spatial disorientation( SD) problem inside the spacecraft,especially in large vehicles with complex three-dimensional architectures such as the space station. This problem can significantly affect the performance of astronauts in orbit. However,if the crewmembers have relevant preflight practice or have received adaptation training,they may be relieved from the disorientation. Based on the review of three typical spatial disorientation problems and the related countermeasures,the advantages and drawbacks of applying virtual reality( VR) to preflight adaptation training( PAT) were analyzed by comparing with several commonly used methods in the aspects of weightlessness simulation,visual simulation and navigation tasks. In addition,the current research situation of spatial orientation training based on VR was summarized and the suggestion on further study was proposed.
