6. Study of oblique whistler waves in coronal mass ejections observed by Solar Orbiter
Kandidat-uppsats, Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : In this paper a search routine in MATLAB was developed in order to find and analyze oblique whistler waves in the data from the ESA and NASA spacecraft Solar Orbiter. Oblique whistler waves are a type of plasma wave which propagate at an angle with respect to the background magnetic field. LÄS MER
7. CoordinateFree Spacecraft Formation Control with Global Shape Convergence under VisionBased Sensing
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Formation control in multi-agent systems represents a groundbreaking intersection of various research fields with lots of emerging applications in various technologies. The realm of space exploration also can benefit significantly from formation control, facilitating a wide range of functions from astronomical observations, and climate monitoring to enhancing telecommunications, and on-orbit servicing and assembly.

8. Vacuum Chamber Adaptation for Low-Power Electric Propulsion Testing : Optimizing Anode Configuration and Electrical Interface for Hollow Cathode Testing, and Conceptualizing a Setup for Field Emission Electric Propulsion Testing
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. LÄS MER
9. Investigation of Antenna Radomes in Low Earth Orbits
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

10. A quantitative analysis of plume gas distributions from different detection studies on Europa
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The search for water has been vital in our solar system as water indicates a potential for life. The search has been extended to satellites orbiting the outer planets. It has already been proven that water exists on Saturn’s moon, Enceladus, where the spacecraft Cassini did a flyby through a water plume. LÄS MER
