  1. 1. Starshades: Geoengineering Solutions and Technosignatures in Direct Imaging Phase Curves

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Claudia Skoglund; [2023]
    Keywords : Starshades; extraterrestrial intelligence; stellar evolution; technosignatures; phase curves; direct imaging; habitable zone.; Physics and Astronomy;

    Abstract : The stellar luminosity increases as a star evolves which inevitably yields a higher temperature on planets in orbit around the star. It is reasonable to assume that intelligent civilizations would tackle this issue through installing artificial structures that can alter the radiation received by the planet. READ MORE

  3. 2. Analyzing Synthetic Spider Silk-based Diffraction Grids for the Sunshade Project

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Johanna D'Ciofalo Khodaverdian; Amira Karlsson; [2023]
    Keywords : Sunshade project; Diffraction grating; Artificial spider silk; Climate change; Geoengineering;

    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.

  4. 3. Consensus Algorithm with Input Constraints and Collision Avoidance for Swarming Sunshade Satellites near the L1 point

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Felicia Törning; [2022]
    Keywords : Consensus algorithm; Formation control; Multi agent system; Solar sailing; Space based geoengineering; Konsensusalgoritm; Formationskontroll; multiagent system; solsegel;

    Abstract : 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.

  5. 4. Lunar Gravity Assist for Electric Propulsion Satellite - For Moving Satellites to Build a Space Sunshade

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Love Dickéus; [2022]
    Keywords : Geoengineering; Electric Propulsion; Gravity Assist; Lunar Gravity Assist;

    Abstract : 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. READ MORE

  6. 5. Electric propulsion of satellites as an alternative for implementation of a sunshade system

    University essay from KTH/Fysik

    Author : Maheen Arfan; Isabelle Bonnier; [2022]
    Keywords : Geoengineering; Sunshade system; Electric propulsion; Orbital mechanics; Sub-lagrange;

    Abstract : As an alternative solution to global warming, this thesis explores the possibility of aspace-based geoengineering scheme that may prove worthwhile to implement in parallel toother environmental efforts that help mitigate impact of climate change. One suggestionof a geoengineering solution is deploying a large number of sunshades in the vicinity ofthe first Lagrange point of the Sun-Earth system, and this prospective sunshade projectwould serve to shield Earth from incident solar radiation.
