由以色列-美国初创公司StemRad开发的可穿戴防辐射背心AstroRad随NASA的Artemis I无人月球往返任务完成了首次飞行测试[1]。该背心由公司领导人Jordan Houri和Oren Milstein主导研发[1]。
根据飞行数据分析，AstroRad背心的防辐射性能与Orion飞船内置的防护shelter相当[1]。太阳风暴是宇航员的主要威胁，1972年8月期间发生的太阳风暴曾释放足以增加宇航员癌症风险或引发辐射病的强质子束[1]。此次成功的太空测试表明，这种可穿戴式防护装备有望为未来月球和火星任务中的航天员提供关键保护。
A wearable radiation-protection vest developed by Israeli-American startup StemRad has completed a successful flight test to the Moon and back aboard NASA's uncrewed Artemis I mission.[1] The AstroRad vest was designed to shield astronauts from hazardous solar radiation during deep space exploration.
Analysis of flight data revealed that the vest's radiation-protection capabilities matched those of the Orion spacecraft's built-in shelter system.[1] This achievement offers a promising solution to address the risk of solar particle storms—such as the intense proton event that occurred in August 1972, which exposed astronauts to radiation levels capable of increasing cancer risk or triggering acute radiation sickness.[1] Led by founders Jordan Houri and Oren Milstein, StemRad has demonstrated a practical approach to protecting crew members during future lunar and Mars missions.[1]
