Soyuz spacecraft launches 32 fish, hippo to space station, space.com via Fox
"I think it's going to be something special, and I will get unforgettable memories," Novitskiy said in a NASA briefing before the mission. Novitskiy picked a small toy hippo, a gift from his teenage daughter Yana, to use an indicator of when the Soyuz reached the weightless environment of space."
Keith's note: Contrary to what some space bloggers and writers have suggested, this is not a "hippo". Rather, it is a plushie version of Suni Williams' dog "Gorbie" Indeed, she pulled the plushie version of Gorbie out for me during the on-orbit interview I did with her in September - more than a month before this recent Soyuz was even launched.
THIS is what a hippo looks like in a Soyuz.
