Some results[which?] from the measurements were published in July 2019.
The ASIM payload has a mass of 314 kg (692 lb) and consists of sub-systems CEPA and DHPU, and two scientific instruments called MXGS and MMIA:
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.
