The mysterious event occurred on September 9 in the night sky: many photographers spotted a strange glow coming from the space transportation system, better known as the Space Shuttle.

Naturally there arose many questions. Where? Why? Accident?

But as always, the true is much more prosaic: a visible mark is nothing like dumping the dirty water (urine). Such a bright trace, was due to the large number (about 68 kg) of the substance. So all we have seen quite a common phenomenon, by NASA spokesman. When water getting out to space, it discards into a cloud of tiny crystals and subsequently under the influence of sunlight evaporates and dissipates in space.
