The beautiful trail in the sky looked like a mysterious
celestial event. In reality, it was urine.

Some skygazers were treated to the unexpected view of a
bright sparkling glow Wednesday night, created when astronauts aboard the space
shuttle Discovery dumped the waste
out into space.

The water dump was a scheduled task for STS-128 pilot Kevin
Ford, who poured out urine
and waste water
stored aboard the shuttle in preparation for a landing
attempt Thursday. Weather thwarted that try, but astronauts plan another
landing attempt Friday at 5:48 p.m. EDT (2148 GMT) in Florida, though rain and
high winds are expected again.

The light show Wednesday was aided by an unusually
large amount
of water being dumped all at once – about 150 pounds (68 kg),
said NASA spokeswoman Kylie Clem. Discovery had just undocked from the
International Space Station the day before, and had not been able to unload
waste water during the 10-day visit.
