美国太空总署（NASA）计划在2024年前，启动名为“月亮女神号”（Artemis）的载人探月计划，把一对男女太空人送上月球，后者更将是首名登月女性。NASA日前在官网，公布特别为是次征空计划设计的新款太空衣，其中一个特点是令太空人活动更自如。

新太空衣名为“探索舱外机动装置”（xEMU），以先进物料制成，能抵受摄氏零下156度至摄氏121度的极端温度。为抵挡月球表面含有如微细玻璃碎土壤冲击，xEMU具备防刮损功能，确保太空人不会吸入宇宙尘和被辐射污染。

NASA以3D扫描太空人的体形，为他们度身制造xEMU，让他们穿得更舒适。太空人以从太空衣后方进入的方式穿着，令他们与太空衣上半身更紧贴，并减低肩膊被坚硬太空衣撞伤的机会。太空衣下半身部分各关节亦以特别物料制成，让太空人可更灵活地在月球上步行，不用像以往要如兔仔般弹跳。

除此之外，太空衣头盔和上半身部分内置重新设计的通讯系统，能自动将太空人说话的声音传送给同僚和地面控制中心，避免旧款太空衣耳机系统因为太空人出汗潮湿，导致收音效果欠佳的弊处。
