Using the flight data, the team calculated the vest would shield an astronaut from a solar storm about as effectively as Orion's dedicated onboard radiation shelter, suggesting personal shielding garments could be a mass-efficient alternative to shielding the entire spacecraft. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How well does the AstroRad radiation-shielding vest protect astronauts compared to a spacecraft's radiation shelter? Flight data from an uncrewed lunar trip aboard NASA's Artemis I mission showed the AstroRad vest, developed by StemRad, would shield an astronaut from a solar storm about as effectively as the Orion spacecraft's dedicated heavily shielded onboard shelter, where crew would otherwise have to hide during a storm. _Space engineering enthusiasts follow astronaut safety breakthroughs like radiation shielding on daily.dev._ ## Similar posts on daily.dev - [NASA tells astronauts to shelter in SpaceX Dragon due to new ISS leaks](https://daily.dev/posts/nasa-tells-astronauts-to-shelter-in-spacex-dragon-due-to-new-iss-leaks-53afah9kj) · TechCrunch · 0 upvotes · 0 comments - [Elon Musk chose Vera Rubin for orbit.
