Almost a century after a mysterious explosion in Russia flattened a huge swath of Siberian forest, scientists have found what they believe is a crater made by the cosmic object that made the blast.
The crater was discovered under a lake near the Podkamennaya Tunguska River in western Siberia, where the cataclysm, known as the Tunguska event, took place.

Comment: Maybe the people in NASA know there are not just a few space rocks flying around, but many, and they see no point in investing any money that would reveal a little of their secret to the masses.
