Russian scientists are expecting two cockroaches, who returned from space onboard the Foton-M bio satellite, to give birth to the first creatures ever conceived in space, the research supervisor said.

"In the next few days we are expecting two female ‘cosmonauts’ to give birth to the world’s first offspring conceived in microgravity," Dmitry Atyakshin said.

He said the two expectant mothers are being kept in a separate tank under constant expert monitoring. All space cockroaches feel well, but their behavior and physical condition has changed dramatically.

"The research has just begun, but we can say for sure that, despite the stamina of the cockroaches, weightlessness exerted a serious influence on them, especially on their motor functions – they move slower and get tired quicker," the scientist said, adding that the insects recuperated from the spaceflight amazingly quickly.
