quote [ The Micro-11 mission, which made its way aboard a SpaceX Falcon 9 rocket, amounts to a bunch of containers of frozen human and bull sperm. Aboard the 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. It's perhaps worth noting that the current ISS crew of six men may have had alternative methods for acquiring a whole bunch of human sperm that would have been cheaper than hitching a ride on a multimillion-dollar space launch, but it's understandable why the space agency didn't go that route. ]
