Space vestibulo-neuroscience in the new century

Abstract

In the new century there will probably be more long spaceflights and fewer short spaceflights. There will probably be several flights to Mars, flights that (if chemical rockets are used) will involve one year to get there, a second year on Mars, and a third year to return. The three-year Mars scenario will probably include rotation of the spacecraft to provide artificial gravity. If nuclear thermal rockets are used, a manned exploration of Mars could be accomplished in less than one year. Vestibular research will be directed towards ensuring that astronauts, upon landing on Mars, will be able to walk with confidence and without delay. Research will be required to investigate vestibular adaptation in spaceflight, motion sickness, and the vestibular effects of rotation in space-night. © 1993 S. Karger AG, Basel.
