Atmosphere-Space Interactions Monitor (ASIM) is a project led by the European Space Agency that will place cameras and X-ray/γ-ray detectors on the International Space Station, where it will observe the upper atmosphere to study sprites, jets and elves and terrestrial gamma-ray flashes in connection with thunderstorms.[1] It is hoped that measurements of these phenomena from space will contribute to the understanding of Earth's upper atmosphere.[2]

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.[3] Danish tech company Terma A/S is running the technical part of the project for ESA[4][5] and DTU Space (National Space Institute) from the Technical University of Denmark provides the scientific leadership of the project.[6] Mission operations will be performed by the Belgian User Support and Operations Centre (B.USOC) in Uccle, Belgium.[7][7]

Instruments

The ASIM payload has a mass of {{convert|314|kg|lb|abbr=on}} and consists of sub-systems CEPA and DHPU, and two scientific instruments called MXGS and MMIA:[3][8]

  • The Columbus External Payload Adapter (CEPA) and Data Handling and Power Unit (DHPU) form the structural and electrical connections, respectively, to the Columbus module.
  • The Modular X and Gamma Ray Instrument (MXGS) is a pair of terrestrial gamma-ray flash (TGF) detectors. The low-energy detector is sensitive from 15 keV to 400 keV, and the high-energy detector is sensitive from 200 keV to 40 MeV.
  • The Modular Multi-Imaging Assembly (MMIA) is an optical imaging system capable of observing 12 frames per second continuously in the 777.4 nm and 337 nm bands at 5 nm wide intervals.
