From NASA's Scientific Visualization Studio. Analysis of the meteor that flew in over Russia tells a surprising tale. Shortly after dawn on Feb. 15, 2013, a bolide measuring 18 meters across and weighing 11,000 metric tons, screamed into Earth's ****************** kilometers per second. Burning from the friction with Earth's thin air, the space rock exploded 23.3 kilometers above Chelyabinsk, Russia.

The event led to the formation of a new dust belt in Earth's stratosphere. Scientists used data from the NASA-NOAA Suomi NPP satellite along with the GEOS-5 computational atmospheric model to achieve the first space-based observation the long-term evolution of a bolide plume.
