Strange rays in space

Beautiful impressions appeared in the sky on Wednesday (9 / 9) last night and looks like a mysterious event. But the sparkling light in the sky turned out to be urine water.

Some people who see the beautiful phenomenon in astronauts during space shuttle Discovery remove "dirt" in the sky.

Disposal is scheduled by the pilot Kevin Ford who took urine and liquid waste as one form of preparation for landing on Thursday. But because of the weather, the landing failed and the astronauts planned to land in Florida on Friday at 17:48 local time, in rainy weather conditions that accompanied the wind.
Wednesday the light show made up of about 68kg of water was thrown at the same time, said NASA spokeswoman Kylie Clem. Discovery has left the international space station a few days before and during the 10 days there can not dispose of waste.
"That is a huge amount because it does not do waste water disposal when docked to the station," Clem said via email. "It is a new rule applied in the last two flights to prevent contamination of the Kibo module."

Kibo module is a new research lab in Japan built space station that includes the external platform to expose science to the space environment. Disposal of water from a docked aircraft could potentially interfere with experiments.
In general, Clem said seeing the water in outer space has become public. Waste water usually freezes during the disposal and into the clouds into small ice pellets. Then when exposed to sunlight, the ice is crushed into water vapor and spread in space.

A number of people in North America seem to see Wednesday's disposal, and some are sending pictures to SpaceWeather.com.
One of them was Abe Megahed is a picture at 21:40 hours and taken from Madisson Wisconsin. "I just watched the space shuttle and the station flew past and was surprised to see the plane make a big arch that prides. Is it? Something is from the vents? OMS who burning? Rocket RCS? A record is for the largest discharge of urine?" He wrote.
