The Atmosphere-Space Interactions Monitor (ASIM) is an instrument suite on the International Space Station (ISS) for measurements of lightning, Transient Luminous Events (TLEs) and Terrestrial Gamma-ray Flashes (TGFs). Developed in framework European Agency (ESA), it was launched April 2, 2018 SpaceX CRS-14 flight to ISS. ASIM mounted external platform ESA's Columbus module eleven days later planned take during minimum 3 years.
Terrestrial gamma-ray flashes (TGFs) are transient emissions from thunderstorms, generated by electrons accelerated to relativistic energies in electric fields. Elves ultraviolet and optical excited the lower ionosphere electromagnetic waves radiated lightning current pulses. We observed a TGF an associated elve using Atmosphere-Space Interactions Monitor on International Space Station. The occurred at onset of pulse that elve, early stage flash.

THESEUS, one of the two space mission concepts being studied by ESA as candidates for next M5 within its Comsic Vision programme, aims at fully exploiting Gamma-Ray Bursts (GRB) to solve key questions about early Universe, well becoming a cornerstone multi-messenger and time-domain astrophysics. By investigating first billion years Universe through high-redshift GRBs, THESEUS will shed light on main open issues in modern cosmology, such population primordial low mass luminosity galaxies,...
Abstract While narrow bipolar events (NBEs) could be related with lightning initiation, their intrinsic physics remains in question.
