1. Analyzing Synthetic Spider Silk-based Diffraction Grids for the Sunshade Project
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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. LÄS MER
2. Non-Disposable and Reusable Solar Sails for Transporting Sunshades to the L1' Point
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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'. LÄS MER
3. Consensus Algorithm with Input Constraints and Collision Avoidance for Swarming Sunshade Satellites near the L1 point
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Swarm Control Theory studies how multi-agent systems interact to solve tasks cooperatively. In this thesis it was studied how graph theory and the Dynamic Average Consensus Algorithm can be used to control swarming sunshade satellites near L1 for global temperature control, and if it would be suitable for the purpose. LÄS MER
4. Lunar Gravity Assist for Electric Propulsion Satellite - For Moving Satellites to Build a Space Sunshade
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : One idea to stop the increasing threat of global warming is to build a space sunshade, made up of a constellation of satellites to reflect a portion of the sunlight. These satellites need to reach an equilibrium point where they can stay in orbit with minimal adjustments. LÄS MER
5. Attitude and orbit control analysis of a solar sail spacecraft for Space sunshade missions in the vicinity of the sub-Lagrange 1 point
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : 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. LÄS MER
