They pissed it. You may have missed it.
Recently, there was a fascinating glow in the sky that moved observers to ponder just what it might be.
I am assuming that Space.com is an authoritative source of information, for it informs me that the glow that was seen in the sky by so many last Wednesday was, indeed, astronauts' urine.
NASA spokeswoman Kylie Clem told a press conference that this aurora boreapiss was the result of the space shuttle Discovery releasing an unusual amount of water and urine into outer space.
I have never consciously weighed urine--not even my very strange biology teacher asked me to do that. But apparently about 150 pounds of liquid was sprinkled upon the stars.
Such a large release is relatively new, Clem said, and is related to recent restrictions on waste disposal while the space shuttle is docked with the International Space Station.
Regardless, when you release liquid waste matter into space it apparently freezes. Then the sun bathes it in its beams, turning it into vapor, and it wafts away in a glorious glow like a July 4th firework breathing its last.
Some observers even sent pictures in to SpaceWeather.com. (Go to September 10 in the archives.)
I hope this all doesn't mean that astronauts have stopped.
Either way, it is reassuring that their waste matter is still giving someone at least a moment's psychological uplift before it disappears into the dark beyond.
