Sex in space? Only if you're a lizard. The Russians have reportedly lost contact with a satellite packed with geckos as part of an experiment on how zero-G affects the lizards’ sex lives. Five geckos -- four females and one male -- launched July 19 in a Foton-M4 spacecraft for a 60-day flight. They made a few orbits before the satellite stopped responding to commands from Roscosmos, the Independent newspaper reports. “Kazakhstan, we have a problem”? Hmm. Scientists say they’ll have to regain control of the satellite if they’re to land the geckos safely again. Or the lizards just might prefer to stay lost in space for a while.
