The Spirit of Knoxville:
autonomous trans-atlantic balloon project

We're sending a series of unmanned balloons out to cross the Atlantic Ocean. When (or if) one makes it, it might just be a world record of some sort.

Here's what will happen:
A Spirit of Knoxville autonomous balloon will be released from downtown Knoxville, TN, climb to 42,000 ft, enter the jetstream, and be whisked across the Atlantic Ocean... we hope. All the while a homemade radio will send us its location, height and other health info about the flight. All of this information will be available right here on our site in real-time during missions.

Sign up and we'll let you know when we're having a launch. We usually get about 48 hours notice that the weather is right. We'll keep launching every few weeks or until we make it to Europe or Africa.

Be a part of history in the making, or at least have fun watching us try!
