Moore still explains that re-adaptation to Earth after a 2.5 years flight begins right away on landing, continues speedily for the first 10-12 h and then more gradually for 2-4 days pending pre-flight when stability would be achieved again. It is also observed that similar issues are quantifiable after 30-90 days bed rest. With a prolong stay in bed or in space, the signs are more stern and have a longer recovery period. The customized business dynamic post urography system that is used to encourage dependence predominantly on vestibular function in astronauts is also used to test 100 members of the space flight.
