Mimicking galactic cosmic radiation (GCR) is difficult with ground-based simulations and experimental results are limited by facility constraints. In the past year, we flew two consecutive missions on large NASA scientific balloons (to ~ 38 km altitude) launched from New Mexico (6.5-hr flight) and Antarctica (32-d flight) and will report GCR doses comparable to levels expected at the equatorial Mars surface. Measurements were made in collaboration with the DLR and utilizing the M-42 active radiation dosimeter developed for use on Artemis 1. The M-42 instrument stores data in flash memory, records charged particles over a substantial part of the trapped proton and the GCR LET spectrum, and can be easily integrated into payloads due to its compact size (182 x 44 x 22 mm; 237 g) and internal battery (up to 6 weeks of operation). Our presentation will provide an overview of the two recent balloon missions (payload description; flight profiles), and summarize the radiation data collected in the middle stratosphere, highlighting how robust, real GCR exposures can be achieved without needing to fly orbital or deep space experiments.
