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...

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...

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...

The JUICE spacecraft is an ESA mission to the Jovian system that will be launched in 2022. It will collect scientific data about Jupiter and its Galilean moons thanks to a flyby tour of Europa, Ganymede, Callisto and a final Ganymede orbiting phase. A high number of flybys will be performed with minimumaltitudes of 200 km. The tracking of the...

The habitability of exoplanets is determined by their surface properties and atmospheres, spectropolarimetry is a powerful tool to characterize these. Numerical models can be used to simulate the polarimetric signals of these exoplanets, but these computed signals have to be compared with observations. The best test-case for such a comparison is...

During the entire era of space flight air launch is seen as a very promising concept. Despite its claimed advantages, air launch is up till now only a marginal success with the Pegasus launch vehicle from Orbital Sciences. In this study is investigated for which conditions expendable air launched vehicles can achieve a performance gain compared...

55 years have passed since the launch of the first man-made space vehicle, Sputnik 1. While spaceflight has changed significantly in many ways, further improvement in rocket technology is still being pursued. Launch-assist systems, which give the launch vehicle a combination of initial velocity and initial altitude, could create such an...

The Cryosat-2 mission is an European Space Agency mission with the main objective to measure and monitor the variation in sea-ice and main ice sheets on Earth, located at Greenland and Antarctic. The satellite's main instrument is a state of the art altimeter, which can measure the distance between the satellite and the ice surface with extreme...

A transition through the Earth's atmosphere is inevitable if it is desired to bring or return something useful from space. The transition is also known as the atmospheric entry, which is characterised by a highly energetic vehicle. Three types of entry can be distinguished: ballistic, glide and skip entry. In the hypersonic transition of a glide...

Four decades after Neil Armstrong's 1st steps on the Moon the time has come to take it one step further, the permanent occupation of humans on lunar soil. Permanent occupation of humans will revive the dream of exploring space and will open the doors for space flight to Mars or even further. For this reason this project investigates the...

Saturn’s moon Titan is unique in that it is the only moon in the Solar System with a significant atmosphere. Its atmosphere is thicker than the Earth’s and it contains several layers of hazes. Knowing the properties of the hazes is crucial for understanding the existence and evolution of this atmosphere and the dynamical processes that take...

In the past few years, a new spirit for the exploration of the Solar System spread among the space community and reaching the Moon has been set as the first step of this new program. In this frame, going back to the Moon is needed to familiarize with a new way of living in a different environment, adapting to it and testing new technology. It is...

Understanding the Sun's natural processes helps us to understand how the Earth responds to the Sun's variations and helps improve our ability to predict its behavior. A probe in polar orbit around the Sun would be able to help provide a more complete picture of the Sun by studying coronal features from various angles, by linking particle and...
