[Use of elongated and shortened days in space flights].
On the basis of the experimental findings and the literature data it is concluded that a 24-hour day should be recommended for space missions. It is assumed that in future prolonged or shortened days may be used. This is confirmed by the hypothesis that the information-energy cost of the diurnal cyle is constant.
