I is for International Space Station
There's a Lot of Sperm on the International Space Station Right Now. For the first time, err, officially, NASA will set loose human sperm in outer space.
The Micro-11 mission, which made its way to space aboard a SpaceX Falcon 9 rocket's Dragon resupply capsule, amounts to a bunch of containers of frozen human and bull sperm. Aboard the International Space Station (ISS), scientists will thaw the sperm, according to a NASA statement, and then study it to see how weightlessness affects its ability to move and prepare to fuse with an egg.
