November 1, 2000 was the first day Castanet went online. Over its twelve years it has changed a great deal as seen in this short video. 

Do you remember the many faces of Castanet over the years?  Feel free to pause it and read some of the old headlines.

On October 31st, 1952 the U.S. tested out it's very first hydrogen bomb in Operation Ivy-Mike. 

This video shows you just how incredible the explosion was; in fact, the enormous explosion was the 4th largest device ever tested by the U.S.

The mushroom cloud climbed to 57,000 feet in only 90 seconds, entering the stratosphere. One minute later it reached 108,000 feet, eventually stabilizing at a ceiling of 120,000 feet. Just 30 minutes after the test the mushroom stretched an incredible 60 miles across.
