Of the four laboratory mice that went into space aboard China's Shenzhou-21 spaceship, two of them gave birth to triplets within three months of returning to Earth.
Researchers say that mother mice that have been to space are more prolific than ordinary mice, and the baby mice have different personalities.
This pair of "mouse parents" who have been to space now live with their babies at the Institute of Zoology, Chinese Academy of Sciences. Researchers record their situation around the clock using cameras.
This prolific pair of "mouse parents" went to space aboard Shenzhou-21 at the end of October last year and returned to Earth in mid-November.
Researchers say that female mice that have been to space reproduce two to three more offspring than female mice on Earth.
Researchers also found that the personalities of each litter of mice are different, and the first litter is the most "socially anxious".
