1. Cosmic Dust Detection by the Solar Orbiter Using Machine Learning
Kandidat-uppsats, Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : This project aims to investigate neural network systems as an effective tool for the in-space captured dust impact signal detection. Cosmic dust is the nanometre to micrometre fine-sized particles that exist in the interplanetary region. They originate from comets, asteroids, the planets and their moons and rings, or even the interstellar region. LÄS MER
2. Trajectory Optimisation of a Spacecraft Swarm Maximising Gravitational Signal
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : Proper modelling of the gravitational fields of irregularly shaped asteroids and comets is an essential yet challenging part of any spacecraft visit and flyby to these bodies. Accurate density representations provide crucial information for proximity missions, which rely heavily on it to design safe and efficient trajectories. LÄS MER
3. Making Space Exploration Sustainable: A Quantitative Assessment of Valuable Elements for Implementation of In-Situ Utilisation of Lunar Resources
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Exploring the Solar System is an ongoing process of humanity that cannot be stopped. It requires large amounts of resources to explore space, which need to be acquired from somewhere. Resources mined on Earth cannot be diverted from vital productions on Earth as those required for energy systems transition and developing a sustainable society. LÄS MER
4. 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 geovetenskaperSammanfattning : 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. The visibility of double neutron star binaries to LISA
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Double neutron star binaries (DNSBs) in the mHz gravitational wave (GW) regime are an important group of objects which the GW detector LISA will be able to observe. The detection and parametrization of these objects will help develop our current understanding of neutron star formation and evolution. LÄS MER
