DLR M-42 EXT radiation detector – four flight units and four backups
The radiation biology team at the DLR Institute of Aerospace Medicine has further developed the M-42 radiation detector, particularly with regard to its measurement electronics. The latest addition to the detector family, the M-42 EXT (extended), can measure space radiation more accurately during Orion’s lunar orbit on the Artemis II mission than the previous version used on Artemis I. In addition, the new devices feature an on/off switch (see inset, lower right). The Orion crew will switch on the four identical dosimeters after launch and attach them with Velcro fasteners at four locations within the spacecraft, each shielded to various degrees from space radiation. In total, the DLR team designed, built, calibrated and tested a set of eight identical detectors: four flight units and four backup devices.
