At the Edge of Space (1 x 60′) – Between the blue sky above us and the infinite blackness of space lies a frontier full of enigmas that scientists have only just begun to investigate.
This film takes viewers on a spectacular exploration to probe the earth-space boundary zone, which is home to some of nature’s most puzzling and alluring phenomena: the shimmering aurora, streaking meteors, and fleeting flashes that shoot upwards from thunderclouds, known as sprites. Discovered in 1989, sprites have eluded capture because they flicker into existence for a mere split-second—40 times faster than an eye blink.
We ride with scientists in a high-flying weather observation plane as they hunt for sprites and finally succeed in snaring them in 3D video, gaining vital clues to unravel their mystery. Advanced video technology is combined with stunning sequences shot from the International Space Station.
