Atmosphere-Space Interactions Monitor


Atmosphere-Space Interactions Monitor is a project led by the European Space Agency to place cameras and X-ray/γ-ray detectors on the International Space Station to observe the upper atmosphere in order to study sprites, jets and elves and terrestrial gamma-ray flashes in connection with thunderstorms. It is hoped that measurements of these phenomena from space will contribute to the understanding of Earth's upper atmosphere.
The ASIM components, originally planned to be completed in 2014, were launched on 2 April 2018 and mounted on the Columbus External Payload Facility on 13 April 2018. Danish tech company Terma A/S is running the technical part of the project for ESA and DTU Space from the Technical University of Denmark provides the scientific leadership of the project. Mission operations will be performed by the Belgian User Support and Operations Centre in Uccle, Belgium.
Some results from the measurements were published in July 2019.

Instruments

The ASIM payload has a mass of and consists of sub-systems CEPA and DHPU, and two scientific instruments called MXGS and MMIA:
