The Russian geckos that were lost while having sex in space – and then found again – have all been found dead upon their return to Earth, according to the Russian space agency.
However, a joint statement from Roscosmos and the Academy of Sciences' Institute of Medico-Biological Problems now says that all the geckos died on board.
Roscsomos said that: "It was established that while the Drosophila flies handled spaceflight well, developed and bred successfully, all the geckos, unfortunately, died. The date and circumstances of their deaths will be established by specialists."
The Moscow Times reports that scientists will have to view 44 days worth of video footage to determine exactly when the geckos died, and if they ever actually had sex.
