Earlier this summer, we told you about radiation experiments being conducted on the Bigelow Expandable Activity Module (BEAM) aboard the International Space Station (ISS). In June, NASA researchers at the Johnson Space Center began taking real-time measurements of the dosage of Galactic Cosmic Radiation (GCR) levels inside the BEAM with two active Radiation Environment Monitors (REM). Researchers are working to analyze this radiation, to check if the BEAM's shielding properties can be applied to long-term missions, and the ISS crew used the Made In Space zero gravity 3D printer to manufacture a 1.1 mm thick radiation shield, which was installed onto one of the REM sensors for a multi-month experiment. We've just learned from Made In Space that the third of these three radiation testing device prints has been completed, using its Additive Manufacturing Facility.
