It looked like future NASA astronauts in training Wednesday in Chattanooga.  Students from The Bright School launched the new Little Debbie's Cosmic Cupcakes into space.

Channel 3 Chief Meteorologist Paul Barys was on hand with them at the Challenger Center, explaining how the weather balloon works.

The balloon was fitted with Go Pro cameras and a GPS tracking system.  The cupcakes are expected to get more than 18 miles high.  The cupcakes are expected to leave the earth's atmosphere.

Their anticipated landing area: somewhere in the Nantahala National Forest.
