To launch a rocket to the edge of space using a pressure fed rocket system with liquid oxygen as propellant, you need to know exactly how much pressurant gas (helium) you need to take along. In this thesis a practical investigation on cryogenic tank pressurization is conducted together with DARE. The measurement results are used to validate...

This thesis presents the results of a developed density inversion tool, which estimates lunar crustal density anomalies from Bouguer anomalies. The tool is run through a number of tests for verification, culminating in the forward modeling and subsequent inversion of synthetic density anomalies, showing a > 97% recovery of the original density...

The ballistic coefficient β of a satellite indicates the influence atmospheric drag has on the orbital decay of said satellite. The method developed in this study estimates the ballistic coefficients of 1U CubeSats by analysing both its historical TLE data and the density it experienced along its trajectory according to the empirical density...

An interesting concept related to photovoltaic energy is Concentrated Photovoltaics (CPV), in which sunlight is focussed on a PV cell through lenses and mirrors, thereby increasing the incident irradiance on the PV cell. Solar concentration is proven to not only increase the output power of PV cells, but also to increase the electrical...

The Jupiter flyby of Cassini in 2001 allowed to study the gas giant in detail. Jupiter’s inner magnetosphere is populated by high energy particles, causing an intense radiation observable throughout the microwave regime. The re-calibration of the Cassini RADAR instrument has allowed for constraining the energy distribution of the electron...

The use of deployable structures for space telescopes has the advantage of enabling options to improve their optical performance and reducing the launch volume. The Deployable Space Telescope (DST), which is currently developed by the Space Systems Engineering (SSE) department, will make use of a high precision deployable structure to extend the...

Re-entry is a term that is applied when one would like to transport some (human) payload from an orbit around a certain body towards the surface of that body. With an entry velocity of multiple kilometers per second, having the vehicle carrying this payload not smashed into pieces at the end of flight is one of the key points of re-entry. Using...

In recent years it has become feasible for private entities to launch smaller satellite missions. However, these entities usually lack worldwide tracking and communication abilities. Therefore, autonomy is becoming increasingly important. In this thesis project a flexible, autonomous navigation system was designed, which uses magnetometers, Sun...

Active propulsion is required in order to further develop the capabilities of small satellites like CubeSats. At TU Delft a micropropulsion system is being developed based on a Vaporizing Liquid Microthruster (VLM), using liquid water as propellant. This research presents the manufacturing, characterization and testing of an existing VLM-design....

In 1997, the descent of the lander Pathfinder into the Martian atmosphere revealed temperatures in the meso- sphere below CO2 condensation point. As CO2 is the main constituent of the martian atmosphere, the pres- ence of mesospheric CO2 ice clouds has been suggested, and then confirmed by spectro-imaging observa- tions coming from satellite...

Space debris, composed of man-made objects orbiting around Earth in an uncontrolled fashion, represents a critical issue for long-term sustainability of outer space activities and for space safety. A reliable and accurate mapping and monitoring of space debris is therefore a critical necessity for modern space industry. For relatively low...

The role of traditional entry guidance systems is to ensure that the vehicle is brought from a nominal entry interface point (EIP) to the neighborhood of a designated landing site at an acceptable energy state. Such systems are designed in such a way that the landing site can be safely reached even if off-nominal conditions are present at the...

Focusing on the rapidly increasing debris population around Earth as well as the scientific and corporate interest in Asteroids, multiple missions for interaction with non-cooperative bodies have been proposed over the last years. Applications such as the Electrostatic Tractor (ET) aiming to reduce the debris populations and missions introducing...

The success of CubeSat, after 2005, resulted in bright future expectations of Spacecraft with a mass below one kilogram. Although these spacecraft are usually known as Pico and FemtoSat, their ambiguous nature and inconsistent use in literature resulted in the use of an alternative, namely Sub One Kilogram Spacecraft, or simply said SOKS....

The definition of the CubeSat is already nearly two decades old. This results in the trend that a large fraction of CubeSat missions are leaving the domain of (educational) technology demonstration and entering that of commercial applications. Therefore a larger focus is put on the reliability and compatibility of commercial of the shelf systems...

Conventional control techniques, such as PID control and LQRs, are commonly used to design the attitude control laws for entry vehicles. However, in the non-aerospace industry, expert or knowledge-based control methodologies, such as neural networks, fuzzy logic, and model predictive control, are commonly applied to improve to performance of the...
