To anyone who's ever pondered what urine looks like in space -- c'mon, don't be shy -- we say: wonder no more, because photos of the phenomenon have finally hit the internet.
Last Wednesday, a number of skygazers were lucky to sight a mysterious flare in the night sky, that, as it now turns out, was a 150-pound cocktail of astronaut urine and waste water released from the shuttle Discovery.According to NASA spokeswoman Kylie Clem, because space regulations bar astronauts from dumping waste water at the International Space Station, the Discovery astronauts had to wait until undocking before they could discard their pee -- which by that point amounted to a hefty ten days' worth.
Sad you missed the show? No need to worry: you may get another chance, as it's actually a fairly common sighting, says Clem.
