The Seed Hub launched on June1st 2013 (outside US). The flight time was roughly three hours and the balloon traveled about 95,000 feet (19 Miles) above earth and a distance of 67 miles. It was damn hard to track, but Mission Accomplished!
Aboard was (1) Joint, (1) Clone, and 95 seeds. First in History!
Unfortunately we’re not sure if 19 miles above earth is classed as “space” but it’s cool none the less!
