CO Satellite Launch

A pair of NASA satellites are on their way to work.

They blasted off early today from Vandenberg Air Force Base in central California for a look at both sides of the ice cream castles in the air.

The satellites CloudSat and Calipso carry advanced instruments that can view clouds in 3-D.

Scientists hope the enhanced view will help them understand how clouds and airborne particles known as aerosols influence weather and climate changes and affect air quality.
