Advancements in the space sector have driven the democratization of planetary exploration. As a longstanding target of scientific interest, Mars will consequently witness an increasing demand for surface missions of various sizes. Its thin atmosphere, however, is a challenging environment for entry, descent, and landing (EDL). An incoming...

The origin of the Martian dichotomy is subject to question and no substantial evidence exists. Some surface and interior features that are not visible in, e.g., topography data, can show up in gravity data. Therefore, this research inverts gravity data to find a crustal and mantle global density model. Previous research performed a one-layer...

Embracing the innate human desire to explore and expand our horizons, Mars presents an unparalleled opportunity to secure the future of our species and inspire generations to come. Aiming to facilitate a sustainable human presence on Mars, this master thesis focuses on the design and modeling of an in-situ rocket propellant production plant to...

CubeSat missions have been deployed to cislunar space and beyond, paving the way for the next significant advancement: a dedicated CubeSat mission to explore a planet near Earth. To contribute to this goal, the German Aerospace Center (DLR) has developed radiation-hardened small satellite technologies, including communications, power and onboard...

Insertion maneuvers are used to move a spacecraft from an open orbit (parabolic or hyperbolic) into a closed orbit around a target body. These maneuvers are key components in any space mission considering orbiting a body for a large amount of time, for exploration or landing; the hyperbolic orbit will be the one that will be used to transfer...

Future Mars exploration missions require safe and controlled landing on the planet’s surface. Conventional entry, descent and landing (EDL) technologies, such as parachutes and rigid aeroshells, face limitations in meeting increasing demands for heavier payloads, harsher entry conditions, and desired landing locations due to their limited...

Fresh water is an essential resource for life. Yet, overexploitation of water resources, rainfall shortages, and a decrease in water quality by pollution increase water scarcity worldwide. Since agricultural production consumes about 70% of the available fresh water resources, it is particularly vulnerable for water scarcity. Therefore, this...

Desert sand acoustic emissions are produced when a “sonic sand” is sheared locally or by a natural dune slipface avalanche, resulting in a brassy sound between 50 and 400 Hz. This type of sediment exhibits particular granulometric, shape and surface characteristics, due to the grains’ erosion and transport history, and emits sounds when the...

On the 14th of July 2013, a methane peak was observed in the Gale crater. This methane peak has been investigated in a non-biological context before. This study applies exoplanet research strategies and knowledge about biological methane production on Earth to investigate the biological context. Bayes formula is the foundation of the Bayesian...

Cragg, Phil (author)
Presently, there exists no “off-the-shelf” option for power generation on the order of magnitude necessary for sustaining a long-term human presence on the surface of Mars. In this thesis work, an investigation was performed to determine the optimal design for a large-scale, static, autonomously deployable, lightweight Martian surface solar...

Recent studies have shown the feasibility of differential dynamic programming (DDP) in optimizing Earth-centered solar-sail trajectories. In order to further demonstrate the ability of DDP in the optimization of solar-sail trajectories, this work investigates the performance of DDP for optimizing interplanetary solar-sail trajectories. The...

For the first time since the 1970s, concrete plans are in motion to bring humans back to the Moon through the Artemis programme. The dawning era of space exploration aims to set the groundwork for long-term off-Earth settlement, with sights on bringing the first humans to Mars. In order to provide a safe means of inhabiting extraterrestrial (ET)...

Madabhushi, Pranav (author)
To survive on the surface of a near atmosphere-less Mars, humans must be able to provide thermal energy to buildings to sustain temperature changes from -73°C to 20°C. The goal of the thesis is to create a passively-working thermal battery using materials currently available to humans; it must be the sole heat source to the Martian buildings....

Hedayati, R. (author), Stulova, Victoria (author)
Due to payload weight limitations and human vulnerability to harsh space conditions, it is preferable that the potential landing location for humans has an already constructed habitat preferably made from in situ materials. Therefore, the prospect of utilizing a readily available Martian material, such as regolith, in an easily programmable...

Heavily resource-reliant transportation and harsh living conditions, where humans cannot survive without a proper habitat, have prevented humans from establishing colonies on the Moon and Mars. Due to the absence of an atmosphere, potential habitats on the Moon or Mars require thick and strong structures that can withstand artificially...

This study presents a hybrid framework to predict stability solutions of buried structures under active trapdoor conditions in natural clays with anisotropy and heterogeneity by combining physics-based and data-driven modeling. Finite-element limit analysis (FELA) with a newly developed anisotropic undrained shear (AUS) failure criterion is...

Mars is expected to become a focal point of exploration (human and robotic) in the coming century, with a very likely need for a robust space infrastructure. Be it communication and navigation satellite constellations or scientific missions in low Mars orbits (LMO) and Areosynchronous orbits (ASO), every individual satellite will have a...

Well clogging was studied at an aquifer storage transfer and recovery (ASTR) site used to secure freshwater supply for a flower bulb farm. Tile drainage water (TDW) was collected from a 10-ha parcel, stored in a sandy brackish coastal aquifer via well injection in wet periods, and reused during dry periods. This ASTR application has been...

Interplanetary CubeSat missions are currently becoming more popular, with a significant number of recently planned missions. The context of this paper is a Mars mission, starting from a parking orbit around Earth: the adoption of a chemical propulsion system for the Earth-Mars transfer phase is investigated, considering the recent...

For economic, scientific and survival reasons, colonisation of other planets is proposed. Mars is the most suitable place to start. To start an early Martian colony, viable In-Situ Resource Utilisation (ISRU) methods of low energy consumption are required to manufacture strong bulk construction materials. Most other studies have used infeasible...
