A mainland satellite that took four ants on an 18-day journey orbiting the Earth returned home on Friday, Xinhua reported.
But unfortunately, the ants - a queen, a king, a worker and a soldier - did not survive their mission aboard the recoverable satellite.
Nevertheless, Xinhua said 30 ant eggs of various ages on board the satellite had been successfully recovered.
It also hailed the recovery of the satellite as another success for China's space industry.
According to the company behind the experiment, it marked an important step for research on heredity and the variation of species in space.
'The remaining eggs are quite valuable. Their physical, chemical and biological changes [during their journey] will be an important issue for scientific research,' said Ma Hong , president of Sichuan Gold Ants Biological Technology Development.
