1. 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
2. Attitude control using ion thrusters for solar sailing from Low Earth Orbit to sub-L1
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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. LÄS MER
3. Hardware-in-the-loop simulation and testing of the ADCS of the Beyond Atlas CubeSat
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Beyond Atlas, a company based in Danderyd, Sweden is working on a Low Earth Orbit (LEO) 3U-CubeSat (Cube Satellite) exploration mission. As part of their maiden mission, they aim to validate the navigation, propulsion, and communication techniques of a CubeSat while it performs orbital maneuvers to collect photographs of space debris.

4. Feasibility study of the implementation of a space sunshade near the first Lagrangian point
Master-uppsats, KTH/RymdteknikSammanfattning : The lack of strong measures to avoid the possible fatal consequences of global warming is pushing researchers to look for other alternatives such as geoengineering.Within geoengineering, this study focuses on the space based solar radiation management methods.
