A new study suggests a protective radiation vest tested during NASA’s first Artemis moonshot could significantly cut the radiation exposure that lunar astronauts face during severe solar storms. The research is based on testing with a manikin rather than human participants.

The vest is designed to reduce exposure to charged particles emitted during periods of heightened solar activity. According to the outlet descriptions, it was evaluated during the Artemis mission as part of efforts to assess potential health and safety measures for future work on the Moon.

The sources align on the central point: the vest can reduce radiation exposure during solar storms, and the study’s findings come from manikin tests tied to NASA’s Artemis program. They differ mainly in presentation and emphasis—one outlet frames the results as a way to “cut” exposure, while another highlights the vest’s link to the Artemis “moonshot” testing and the study’s implication for lunar missions.
