Group 1 - The core finding of the experiment indicates that short-term space flight did not significantly affect the reproductive capabilities of mice, as evidenced by successful mating and birth of offspring after their return to Earth [1][2] - A total of 9 offspring were born from the space mice, with 6 surviving, demonstrating a normal survival rate [1] - The research provides valuable samples for future studies on the effects of space environments on mammalian reproduction [1] Group 2 - The experiment involved 4 mice launched aboard the Shenzhou 21 spacecraft, which were housed in a small mammal breeding facility on the Chinese space station [2] - During the mission, the mice faced a "food shortage" due to adjustments in the Shenzhou 20 return plan, prompting the ground research team to implement an emergency response [2] - The team successfully provided emergency food in the form of soy milk after evaluating various potential alternatives, ensuring the mice's survival during the mission [2]
