1. 1. The development of a Hardware-in-the-Loop test setup for event-based vision near-space space objects.

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Rik van den Boogaard; [2023]
   Nyckelord :Camera optics; Event-based camera; HASTE; Hardware-in-the-Loop testbench; Harris corners; KLT; Asteroid; Frame-based camera; Near-space objects; Planetary exploration; Space-simulated conditions;

   Sammanfattning : The purpose of this thesis work was to develop a Hardware-in-the-Loop imaging setup that enables experimenting with an event-based and frame-based camera under simulated space conditions. The generated data sets were used to compare visual navigation algorithms in terms of an event-based and frame-based feature detection and tracking algorithm. LÄS MER

3. 2. 'Oumuamua : An analysis of the the debate regarding the first interstellar visitor

   Kandidat-uppsats, Uppsala universitet/Teoretisk astrofysik

   Författare :Erik Westergren; [2022]
   Nyckelord : Oumuamua; asteroid; comet; Avi; Loeb; extraterrestrial; Pan-STARRS; interstellar; alien; vessel; Oumuamua; asteroid; komet; Avi; Loeb; utomjordiskt; PAN-STARRS; interstellär; farkost;

   Sammanfattning : In the year of 2017 in October a strange object with a hyperbolic trajectory was observed in our solar system. There were several hypotheses that scientists used to try to explain what kind of an object it was, but no one could, according to the scientific community as a whole, perpetuate any of these explanations as accepted consensus.

4. 3. Assessment of metal contents (Ni, Co and PGEs) in asteroids as a potential source of valuable elements for a future green energy society

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Chenglu Peng; [2022]
   Nyckelord :Sustainable Development; critical metals; iron meteorites; asteroids exploitation; resources;

   Sammanfattning : The aim of this work is to assess the feasibility of asteroid exploitation as a potential source of valuable elements for a future green energy society and achieving a long-term sustainable development of our society. This research is based on the compilation of chemical data of elements concentration of 13 groups of iron meteorites from literature. LÄS MER

5. 4. Cooperative Navigation in Space in-proximity of Small Bodies

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Vignesh Kottayam Viswanathan; [2021]
   Nyckelord :Formation Flying; Asteroid exploration; stereovision;

   Sammanfattning : Autonomous proximity operations are the future of Deep space robotic exploration for searchof life, mining for resources and to establish outposts. Part of that future depends on howwell the spacecraft is capable to navigate around the complex environment of the smallcelestial body. LÄS MER

7. 5. Heat and fluid control solutions for deep space CubeSat CGPS

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Filipp Byström-Troyan; [2021]
   Nyckelord :Cold gas propulsion; Thermal control; Computer simulation; Kallgasframdrivning; Termisk analys; Datorsimulering;

   Sammanfattning : This thesis is on the subject of how propellant heating considerations affect the design of a CubeSat cold gas propulsion system. Computer simulation tools are used to analyse heat flow through the system, as well as the fluid flow and phase change of butane. LÄS MER
