HUNTSVILLE, AL (WAFF) -

The threat of asteroids in size, number and potential damage is much greater than scientists at the Marshall Space Flight Center and around the world originally thought.

Bill Cooke of NASA's Meteoroid Environmental Office at Marshall joined a group of international scientists to analyze February's fireball that hit Chelyabinsk, Russia.

Cooke and others say we are seeing seven to ten times greater impact rate of damaging meteors now than telescope surveys predicted.

He and others called for a need for space-based infrared telescopes in addition to current ground telescopes for a 24/7, eye-in-the-sky approach.
