Trajectory Optimization Methods for Low-Thrust Kuiper Belt Flyby Missions

The Kuiper belt is one of the last mostly unexplored regions in the Solar System. Exploration of the Kuiper belt can greatly increase humanity's understanding of the Solar System's formation and evolution. The use of low-thrust propulsion for Kuiper belt missions has the potential to improve the payload mass of the mission due to the high...

Quasi-periodic invariant tori and retrieval of Near-Earth Asteroids using low-energy trajectories

Near-Earth Asteroids (NEAs) have attracted the attention of the scientific community in the last few years. Not only because of their importance to life on Earth but also their scientific potential and possible economic returns. This work explores the use of quasi-periodic orbits to bound the motion of NEAs close to the Earth’s vicinity for...

A Rapid Grid-Search Technique for KBO Exploration Trajectories

The Kuiper Belt is considered to be formed by remnants of the original Solar System, that is why exploration missions to that region are susceptible of having an enormous scientific impact. Nonetheless, it is far away from Earth, missions to KBO targets a significant challenge. Additionally, current methods to identify trajectories that...

Feasibility Study of LUFAR

With the steady increase in space missions, enabled through technological advances and increase of commercialisation within the space flight industry, both more and increasingly complex missions can be designed for space. To this end, the Lunar Zebro project competes within this field through its small lunar rover design, drastically decreasing...

Mission Planning for Deep Sea Robots

Our challenge was to define a format for a mission plan, and develop an application which allows the users of the robot to create a mission plan effectively. This application should assist the user in the process of creating a mission plan as much as possible. Our client was Allseas who was already the sponsor of the LOBSTER project. During the...

Targeting a Mars science orbit from Earth using dual chemical-electric propulsion and ballistic capture

Ballistic capture is a relatively novel concept in interplanetary mission design with the potential to make Mars and other targets in the Solar System more accessible. A complete end-to-end interplanetary mission from an Earth-bound orbit to a stable science orbit around Mars (in this case, an areostationary orbit) has been conducted using this...

Multi-Flyby Mission to a Potentially Hazardous Asteroid: Improving the Earth Impact Probability Knowledge

The feasibility of improving the Earth collision uncertainty knowledge of a potentially Earth impacting asteroid by means of a multi-flyby mission has been researched in this thesis. The feasibility is assessed both from an astrodynamics point of view and from a systems engineering point of view. The astrodynamics part provides knowledge...

Cubesat Deployment Trajectories for the Asteroid Impact Mission

Missions to Near-Earth Objects (NEOs) are a growing trend in spaceflight. The interest for such bodies is not only justified by the threat that they represent for the Earth, but also because they are potential sources of extra-terrestrial materials, provide windows to the past of the Solar System and to planetary formation, and offer a good...

Building on Mars: An Evolvable Design Strategy for the Architectural Engineer

Humans are going to Mars and the plan is to achieve this within the next couple of decades. In mission architectures the habitat is considered a sub-system in the overall mission’s system architecture. In current mission engineering, the crew’s psychology is barely considered in the design of the mission. In aerospace engineering, one refers to...
