On December 8th we launched a 1200g weather balloon into the Stratosphere from France.
The box it was carrying was loaded with cameras, batteries and sensors.
It reached an altitude as high as 23.4km and went through temperatures as low as -32°C.
Filmed with a Canon T4i, a GoPro Hero 3 Black Edition and 2 Mobius Action Cameras (one pointing up, one pointing down).
Music : Baltimore's Fireflies by Woodkid & Marion's Theme by M83.
