The erstwhile Soviet Union had sent many animals to space but most of the animals could not survive the ordeal and died. The Soviets loudly proclaimed their supremacy in space and the real stories about the fate of these animals remained behind the iron curtain.
Something similar happened when Russia sent five geckos into the space for an experiment on sexual reproduction in 0 gravity conditions. However, all the five geckos were found dead when the spacecraft returned to earth.
The reptiles were known as sex geckos and became quite famous. In July the Russian space agency Roscosmos lost contact with the spacecraft which was named as Foton-M4 satellite. Fears were expressed that the life support system may have become defunct. The communication was soon established and the experiments continued. The geckos were unfortunately killed but a colony of fruit flies survived the space trip.
Roscosmos agency wrote in a statement posted on its website, “All the geckos, unfortunately, were killed. The date and conditions of their deaths are being determined by specialists.”
The geckos could have lost their life in any stage of the flight. Experts from the Institute of Biomedical Problems told the Guardian that it was premature to talk about the cause of Geckos death.
A source in the commission which was involved in the project said that the Geckos had froze to death and this could have happened due to the failure of the equipment meant to ensure the temperature of the box with the animals.
