Summary
We revisit mud positioned close to the Earth–Solar L1 Lagrange level as a potential climate-change mitigation measure. Our calculations embody variations in grain properties and orbit options with lunar and planetary perturbations. To attain daylight attenuation of 1.8%, equal to about 6 days per yr of an obscured Solar, the mass of mud within the situations we contemplate should exceed 1010 kg. The extra promising approaches embody utilizing high-porosity, fluffy grains to extend the extinction effectivity per unit mass, and launching this materials in directed jets from a platform orbiting at L1. A less complicated method is to ballistically eject mud grains from the Moon’s floor on a free trajectory towards L1, offering solar shade for a number of days or extra. Benefits in comparison with an Earth launch embody a prepared reservoir of mud on the lunar floor and fewer kinetic power required to attain a sun-shielding orbit.
