ESA -- Do giant flashes of lightning striking upwards from thunder clouds merely pose an extraordinarily spectacular view? Or do they actually alter the chemical composition of the atmosphere, playing a role in ozone depletion and the climate on Earth? This is the key question that may be answered by specially designed cameras, which ESA proposes to place on board the International Space Station. The International Space Station (ISS) is the ideal setting for studies of spectacular natural...

The discharge was observed less than two weeks before the shuttle was lost during its Earth reentry. The authors describe the discharge as a Transient Ionospheric Glow Emission in Red, or TIGER, event. It was recorded by a video camera in the near-infrared...
