Creagh, Conor (author)In recent years, researchers have proposed a variety of approaches to tackle the problem of orbital debris. Debris targets are diverse, and prior knowledge may be limited, with unknown uncooperative debris targets being the most challenging category. A crucial portion of any debris capture scenario is the observation phase during the approach....master thesis 2024

Ronckers, Dennis (author)Accumulations of floating debris at culverts and inverted siphons cause partial blockage of the hydraulic structure’s inlet, leading to an increase in head loss that is also referred to as backwater rise. This effect is of high importance in flood management, because backwater rise associated with floating debris accumulations can cause or...master thesis 2023

Fanizza, Vincenzo (author)Performing crucial activities for space exploration, e.g., debris removal and on-orbit servicing, systems for Rendezvous and Proximity Operations (RPO) are required to be autonomous and scalable. Within this context, learning-based relative navigation has gained significant traction due to the latest advancements in AI and the cost-effectiveness...master thesis 2023

Cuadrat-Grzybowski, Michal (author)Mitigation strategies which eliminate existing space debris, such as with Active Space Debris Removal (ASDR) missions, are now more important than ever regarding the ever-growing space debris population problem. One of the considered ASDR approaches uses a net as a capturing strategy. The benefits of such strategy are to allow for a large...master thesis 2023

Sinha, Ishita (author)Recent launches of satellite constellations in the Low Earth Orbit (LEO) region have increased the collision probability of existing debris objects with active satellites. Monitoring the trajectories of these debris objects is crucial for Space Situational Awareness (SSA) to prevent the creation of more debris due to unwanted collisions. Much...master thesis 2023

Capus, Luana (author)Space debris has become a rising problem in the aerospace community, leading to the need for effective spacecraft collision avoidance processes. Currently, these processes can be called unilateral as only one object in conjunction is considered maneuverable. This thesis focuses on the implementation of a combined action approach to collision...master thesis 2023

Kuijpers, Mika (author)Voxels are cells on a 3D regular grid. Voxel-based scenes have many applications, including frequent use in simulations or games. Over the years, the field of high-resolution voxel scenes has progressed significantly, allowing for compressing and real-time editing of high-resolution scenes. This possibility of editing high-resolution scenes led...master thesis 2023

Rueda Oller, Guillem (author)The Geosynchronous Large Debris Reorbiter concept is an active debris removal method proposed for defunct satellites in geostationary orbit. This method uses the electrostatic tractor (or tug), which is a spacecraft that controls a mutual electrostatic force on a target and uses this force to slowly accelerate the target towards or away from the...master thesis 2023

Pettinari, Yurij (author)Space debris and micrometeoroids are abundant around our home planet and offer both an opportunity of research for scientists and a threat to human’s endeavours in space. Impacts with even the smallest particles can happen at such high velocities that they can damage or destroy an operational spacecraft, creating even more debris and possibly...master thesis 2023

Harazim, Mateusz (author)The issue of space debris in Low Earth Orbit is a growing concern that requires comprehensive solutions. This includes preventing further pollution, removing existing debris, and designing resilient spacecraft that can withstand impacts. This thesis focuses on the improvement of spacecraft shielding structures to provide effective protection...master thesis 2023

de Veld, Frank (author)Thousands of space debris objects remain in space after decades of spaceflight without sustainability regulations. Some of these objects de-orbit naturally, but not objects in the geostationary region for which active debris removal is needed. This thesis presents the case of geostationary debris removal using solar sailing, a propulsion method...master thesis 2022

Conings, Vincent (author)To ensure long-term sustainable access to space, it is of paramount importance that humankind acts to alleviate the space debris problem in near vicinity of Earth. The most effective mitigation strategy for large debris items is provided by active debris removal missions, which remove one or more resident space objects from orbit. The execution...master thesis 2022

Cattani, Benedetta (author)More than one million artificial objects greater than 1 cm are already orbiting around the Earth and this number is expected to grow. In the next three years more satellites will be launched than in the past six decades and the rate of space collisions and explosions is also expected to increase, up until an unstoppable series of collisions,...master thesis 2022

Luggeri, Gianmarco (author)There is a need for environmental sustainability also beyond the atmosphere: Human activities are causing a tragedy of the commons in outer space, and most of the world population does not know anything about it. Outer space has become a non-cooperative game for a few players with infinite resources, in an environment with limited resources. The...master thesis 2022

Ryan, Conor (author)Spacecraft are under constant threat from hypervelocity impacts by micrometeoroids and space debris. Due to their large surface area and hence increased probability of being impacted by debris, solar arrays are of particular concern. For larger, trackable debris objects, collision avoidance manoeuvres can be performed so as the minimise the...master thesis 2022

Leon Dasi, Mireia (author)The number of space objects has largely increased in the recent years, becoming a considerable threat to the present and future of satellite operations and human spaceflight. This introduces a need to accurately compute the risk of collision between satellites and space debris. Current methodologies are limited by the type of encounter and the...master thesis 2022

Rijlaarsdam, David (author)To mitigate the growth of space debris, it is vital that Active Debris Removal (ADR) is performed in the near future. Since ADR will require robust relative navigation, future spacecraft should be marked with fiducial markers that are robustly extracted from an image taken by a chaser spacecraft. To prevent the restriction of robotic movement...master thesis 2021

Schild, Maarten (author)Due to ever increasing accessibility, recent years have seen a fast growing number of launches to space, especially to Sun-synchronous orbit. The spent rocket parts, payload fairings and eventually non-functioning payloads of these launches remain in orbit. It is well-established that this accumulation of space debris over time is quickly making...master thesis 2021

Alforja Ruiz, Iñigo (author)Space debris is becoming one of the major risks to be suffered by operating and future space missions. Recent studies show that the number of potentially hazardous uncontrolled orbital bodies is growing with time, increasing the probability of impact with operational satellites. To counteract this problem, several studies are being suggested to...master thesis 2020

Pieters, Liam (author)Space debris objects with sizes between 1 and 10 cm form the greatest risks for creating new collisions with active spacecraft as they are too small to track and too large to be shielded against. This research has simulated the performance of a space-based laser system on the removal of these small-scale debris objects. The selected system is...master thesis 2020
