Before and after space flight on Cosmos-1887 motor activity of Trigonoscelis gigas beetles kept in darkness was recorded. After flight 6 out of 7 beetles showed reduction of periods of free running circadian rhythms. The fact that the change was not observed in controls suggests that it can be attributed to the effects of O G. It is assumed that in space flight the biological requirements for the day duration are modified.
在宇宙-1887号太空飞行前后，记录了置于黑暗中的巨三角步甲的运动活性。飞行后，7只步甲中有6只的自由运行昼夜节律周期缩短。对照组未观察到这种变化，这表明该变化可归因于太空飞行的影响。据推测，在太空飞行中，对白昼时长的生物学需求发生了改变。
