Following a 14-day mission aboard China's space station, a female mouse has successfully delivered a litter of nine healthy pups back on Earth. The birth marks a major victory for space biology.

As part of the Shenzhou-21 mission, the four mice were sent to Tiangong Space Station on October 31. Soon after returning on November 14, one conceived and gave birth to nine pups on December 10.

With six of the offspring thriving, the mission confirms that short-term space travel does not negatively impact mammalian reproduction.
