The Shuttle has seen something from space can reveal the mystery? No, the launch of the Shuttle itself has suggested that a fall in Russia was a comet. In what sense? Each time you launch the Shuttle in the sky are released 300 tons of water vapor in termosfera, who then come together to form special clouds nottilucenti calls. These clouds of water ice stationed in mesosfera are extremely bright. Here's a picture.
A century ago near the Tunguska river in Siberia Podkamennaja the mysterious explosion swept away millions of trees to an area of 2150 square kilometers. An event that happened in a populated area could have created a cataclysm. In 1927 a Russian expedition went to explore the area affected and found the crater, suggesting that the impact with a great body fell from space.
Today, from Cornell University, a study has linked the event to launch the space. In 1908 it was widely observed clouds nottilucenti throughout Europe (mainly UK), exactly the same as those created by water vapor released by the Shuttle. Hence the comparison: it would have been a comet that fell, released into the large water vapor carried in dowry.
