The electric-pump cycle is a rocket engine configuration that uses an electric motor to power the pumps instead of a turbine. This offers several expected advantages such as simpler design, lower development costs, and easier restartability, but comes with reduced performance compared to conventional cycles. Previous research has primarily...

Synthetic Aperture Radars (SAR) have demonstrated to be great instruments for space-based Earth observation in the microwave frequency. Metasurface antennas, on the other side, are a new type of planar antennas with a great potential for space applications, as they are compact and easy to produce. Several methods have been developed in the past...

Quasi-satellite orbits (QSOs) are orbits around the smaller primary in three-body systems. The MMX mission (developed by JAXA, to be launched in 2024) will use QSOs to orbit Phobos, before landing on its surface. This work studies the feasibility of using the invariant manifolds of three-dimensional QSOs for designing landing trajectories, using...

Using renewable energy to power a Mars habitat is a technological challenge because resources such as solar and wind are significantly weaker than on Earth. This work investigates the feasibility of using airborne wind energy (AWE) systems in combination with solar photovoltaic (PV) modules to power a Mars habitat. The Luchsinger model and the...

The Brik-II satellite is a Nano-Satellite which has the main objective to be a technology demonstrator and prove the use of self owned military satellites. One of the payloads onboard the Brik-II satellite is called the Store and Forward payload. It has the capability to Store and Forward messages from and to different military assets. To...

Electric propulsion is generally characterized by higher specific impulse than traditional chemical rockets, which gives them propellant saving benefits. These have been applied in deep-space missions and micro-satellites. A Pulsed Plasma Thruster consists of two electrodes around a block of teflon. A pulsed discharge ablates the teflon and...

Since the introduction of Hydrazine to the list of substances of very high concern, REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals), there has been an increase in the investigation of “green” propellant alternatives. At the DLR Institute of Space Propulsion, a mixture of Nitrous Oxide<br/>and Hydrocarbons (Ethylene...

Resonance ignition devices utilize the gas dynamic phenomenon to heat propellant gases to their auto-ignition temperature in order to initiate combustion. These devices are a promising alternative to current rocket engine ignition systems. In this thesis a python code was developed to generate a resonance ignition system design. The design was...

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...

Current and future space missions require agile and reliable spacecraft capable of trailing and keeping the required attitude. Most of the agile spacecraft missions are near-Earth based but some are placed far away from Earth and its influence. One example of such missions is the Athena mission, which requires the spacecraft to perform fast and...

During the last decades, large deployable structures are starting to be seen as a plausible configuration to multiple space missions, such as solar sailing, LEO (Low Earth Orbit) deorbiting missions or solar power generation. Technological advances in key areas, such as thin film solar cells or new deployment methods, as well as the...

Large-scale liquid rocket engines require high-speed turbopumps to inject cryogenic propellants into the combustion chamber. Modeling the impact of secondary path and leakage flows on the performance and axial thrust of the pump is critical during the early design phase. Previous studies derived simplified models and empirical correlations to...

With the introduction of Interplanetary Laser Ranging (ILR), the acquired tracking measurements accuracy of planets can be improved drastically (up to a few millimeters) which can result in an improvement in planetary ephemerides of not only the planet which is the target of laser ranging but also other bodies in the solar system due to...

This master thesis addresses the need for a telemetry processing for Delfi Space spacecraft operations, a nano-satellite program of the Delft University of Technology. It lays the groundwork for the telemetry processing system (TPS) implementation and explores the design guidelines for a highly scalable but robust and adaptive architecture.

Agrawal, Abhishek (author)
We study the orbital motion of regolith around asteroids, lofted from the surface due to impact cratering events, to understand the displacement of material on the surface and in orbit. The cratering events could be natural such as from meteoroid impacts, or they can be induced from spacecraft activities such as in-situ sample collection....

Space exploration could be significantly aided by combining the disciplines of machine learning and computer vision, but these disciplines need to be developed further for specific space-related applications to have merit. One of the applications for space exploration is the detection of certain structures designating areas of interest. This...

Fragments of asteroids and comets constantly encounter the Earth and Moon in their orbits, impacting them as meteoroids. Observations of meteor showers on Earth have been studied for at least 50 years, in order to construct accurate Solar System meteoroid models. More recently, Earth-based telescopic observations of the light flashes produced by...

As technology improves, increasingly higher resolution payload can be achieved using Cubesats for Earth observation. The diffraction limit prevents the resolution to up to a few meters for these missions and are confined to Very Low Earth Orbits (VLEO). At these altitudes, strong disturbances act on the system, limiting its lifetime and the...

The objective of this MSc thesis was to design a miniaturised Raman spectrometer that can be used in terrestrial deep ice applications of the IceMole probe. This probe is a manoeuvrable subsurface system for clean in situ analysis and sampling, developed at FH Aachen University of Applied Sciences since 2008, that is now part of a bigger DLR...

Plasma actuators are fully electronic devices without any moving mechanical parts. Hence they have increased reliability and lower complexity when compared to conventional actuators used for same purposes. Mobile components also contribute to increased vibrations, noise, loss of energy and they require lubrication. Non-thermal plasma actuators...
