NATIONAL NEWS — The Russians saw a flash of flight and heard the sonic boom.
The meteor exploded with the force of a nuclear bomb. It did $30 million in damage and injured a thousand people.
And no one saw it coming.
The nation's top science officials were called before Congress Tuesday to explain what they're doing to detect similar threats from space.
The bigger concern, is well, the bigger ones.
Using a football field for perspective, the size of that meteor over Russia would only take you to the 7-yard line. Congress has ordered NASA to track objects that are significantly bigger than the entire field - big enough to wipe out a city.
NASA is pushing ahead with plans to land astronauts on an asteroid by 2025 and improve early detection.
