1. Analyzing Synthetic Spider Silk-based Diffraction Grids for the Sunshade Project
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : To mitigate climate change a proposed space-based geoengineering solutionis to screen off solar irradiance by placing a membrane in between the Earthand the Sun. The feasibility of such a project largely depends on minimizingthe mass of the shading screen and as an extension to the Sunshade projectthis thesis investigated how such a low-mass membrane could be designed.

2. Non-Disposable and Reusable Solar Sails for Transporting Sunshades to the L1' Point
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : This study evaluates the feasibility of reusing lightweight solar sails in order to transport 1.69 * 10^6 sunshades, made out of occulting membranes with free-standing SiO2 nanotube films, to the adjusted sun-Earth Lagrange point, L1'.

3. Attitude and orbit control analysis of a solar sail spacecraft for Space sunshade missions in the vicinity of the sub-Lagrange 1 point
University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikAbstract : This Master thesis report contains a complete attitude and orbit control analysis for solar sail spacecraft in the Circular-Restricted-3-Body-Reference frame. The overall goal of the project is to drive one solar sail from the edge of the Earth Sphere of Influence to a vicinity of the sub-Lagrange1 point. READ MORE

4. Attitude control using ion thrusters for solar sailing from Low Earth Orbit to sub-L1
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : The purpose of the study is to evaluate the possibility of using gridded ion thrusters as a means of attitude control for a solar sail as a part of the sunshade project, which aims to place 10^8 solar sail sunshade spacecraft, each with an area of about 10 000 m^2, at the Sun-Earth Lagrangian point L1 in order to reduce Earth's global temperature. Two types of solar sail sunshade spacecraft were studied. READ MORE

5. Sunshade Demonstrator Spacecraft Earth Sphere of Influence Escape Using a Propellant-free AOCS
University essay from KTH/RymdteknikAbstract : This thesis provides insights to what is peculiar about a solar sail attitude and orbit control system and provides the assessment, in the form of a feasibility study, of the effectiveness of sail tip vanes as a control hardware to escape the Earth sphere of influence. The demonstrator aims to prove the technology for the Sunshade project, a constellation of solar sails located at the Lagrangian point L1 to obscure part of the solar radiation directed towards earth.
