This paper presents an approach to Solar Radiation Management (SRM) using a tethered solar shield at the modified gravitational L1 Lagrange point. Unlike previous proposals, which were constrained by the McInnes bound on shield surface density, our proposed configuration with a counterweight toward the Sun circumvents this limitation and potentially reduces the total mass by orders of magnitude. Furthermore, only 1% of the total weight must come from Earth, with ballast from lunar dust or asteroids serving as the remainder. This approach could lead to a significant cost reduction and potentially be more effective than previous space-based SRM strategies.
本文提出了一种在修正引力L1拉格朗日点使用系留式太阳护盾进行太阳辐射管理（SRM）的方法。与以往受护盾表面密度的麦金尼斯界限限制的提议不同，我们提出的朝向太阳带有配重的配置规避了这一限制，并有可能将总质量降低几个数量级。此外，总重量中只有1%必须来自地球，其余部分由月球尘埃或小行星的压舱物提供。这种方法可能会大幅降低成本，并且可能比以前的天基SRM策略更有效。
