Nooij, S.A.E. Bos, J.E. TNO Defensie en Veiligheid Publication year 2008 Abstract At TNO research is ongoing on neuro-vestibular adaptation to altered G-levels. It is well-known that during the first days in weightlessness 50-80% of all astronauts suffer from the Space Adaptation Syndrome (SAS), which involves space motion sickness, spatial disorientation and motion illusions. After return on Earth the problems re-appear, but now also accompanied by postural imbalance. Standard tests for motion sickness, typically applied in astronaut selection programs, do not correlate with SAS at all. TNO developed a method which effectively simulates SAS on Earth, by exposing astronauts to a hypergravity stimulus of 3G in a human centrifuge for one hour. So far we tested the susceptibility for SIC in 12 astronauts and cosmonauts who also rated their susceptibility for SAS in actual spaceflight. The correlation is 100%, suggesting a common mechanism for any G-level transition, whether it is from 1G to 0G or from 3G to 1G. This paper describes the current status of this research.Dit artikel beschrijft de nieuwste resultaten van het ESA onderzoeksproject 'Motion perception' waarbij de correlatie wordt onderzocht tussen de gevoeligheid van astronauten voor Space Adaption Syndrome (SAS) en Sickness Induced by Centrifugation (SIC) Subject AviationCurrent statusGround basedHypergravityLevel transitionMotion sicknessSpace motion sicknessSpatial disorientationStandard testsCentrifugationCentrifugesManned space flightResearchSynthetic aperture sonarEarth (planet)spacemotion sickness To reference this document use: http://resolver.tudelft.nl/uuid:acd9fca3-e9d5-43ab-8c5e-97f664f04c65 TNO identifier 23771 Source Proceedings of the 'Life in Space for Life on Earth Symposium', Angers, France 22-27 June 2008 (ESA SP-663, December 2008) Document type conference paper Files To receive the publication files, please send an e-mail request to TNO Library.
