Processes of Relaxation in the Ultraviolet Band Specrum by High-Velocity Interaction of Exhaust Products on ISS - Groza (Thunderstorm) (Relaksatsiya - Groza (Thunderstorm)) (Relaksatsia-Groza (Relaxation-Thunderstorm)) - 04.18.18

ISS Science for Everyone

Science Objectives for Everyone
Study on global electromagnetic processes in the Earth’s upper atmosphere (thunderstorms, sprites, etc) in the UV portion of the spectrum.
Science Results for Everyone
Spacecraft light, spacecraft bright. This investigation measures light-emitting phenomena, including those from spacecraft plasma and re-entry spacecraft fragments. Data are also collected on origin and development of global thunderstorm phenomena in Earth’s upper atmosphere, including elves, sprites, and jets. Some measurements reveal a splitting of oxygen atoms in atmospheric layers over seismically active areas where Earth’s tectonic plates converge. Overall, the experiments demonstrate the effectiveness of using UV spectral measurements to monitor natural and man-made global physical phenomena and geophysical conditions in Earth's atmosphere and near-Earth space.

Earth Applications
The results of system and exploratory studies on natural and anthropogenous global phenomena in the Earth’s atmosphere and ionosphere can be used for: development of future Earth remote-sensing spacecraft; development of new approaches to forecasting of earthquakes and other catastrophic phenomena; development of advanced methods for Earth hyperspectral monitoring; collection data about weather and gas composition of the atmosphere and ionosphere; and collection data concerning impacts of space activities on the Earth’s atmosphere and ionosphere (interaction of space vehicles with the atmosphere and ionosphere).

Results/More Information

For the first time in the UV spectrum, an investigation researched spatio-temporal and power budget of global thunderstorm phenomena in upper Earth’s atmosphere (elves, sprites, jets, etc), as well as new, previously unknown data about their origin and development were received over the equatorial Africa.
