NASA used satellite to follow plume left by exploding meteor

20130815-132335.jpg… NASA says sensitive instruments on a satellite allowed them to track the dust plume created by the meteorite that exploded over Russia in February for months.

NASA atmospheric physicist Nick Gorkavyi and his colleagues in Greenbelt, Md., were able to use the satellite data to record a never-before-seen view of the atmospheric aftermath of the explosion of the meteor over the Russian city of Chelyabinsk – coincidentally Gorkavyi’s home town.

That explosion deposited hundreds of tons of dust up in the stratosphere, allowing NASA’s Suomi NPP satellite to gather unprecedented measurements of how the material formed a thin but cohesive and persistent stratospheric dust belt, NASA reported Wednesday.

“We wanted to know if our satellite could detect the meteor dust,” Gorkavyi said. “Indeed, we saw the formation of a new dust belt in Earth’s stratosphere, and achieved the first space-based observation of the long-term evolution of a bolide plume.”

The satellite data showed that four days after the explosion the faster, higher portion of the plume had snaked its way entirely around the Northern Hemisphere and back to Chelyabinsk.

And at least three months later a detectable belt of bolide dust persisted around the planet, the researchers said.

Strange coincidence. Are we sure NASA isn’t hurling space rocks as a potential new weapon?
