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...

The dual spacecraft mission BepiColombo is the first joint mission between the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA) to explore the planet Mercury. BepiColombo was launched from Kourou (French Guiana) on October 20th, 2018, in its packed configuration including two spacecraft, a transfer module, and...

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...

In interplanetary space missions, it is convenient to have a second departure opportunity in case the first is missed. Two distinct approaches to minimizing the maximum of the two Delta-V budgets of such a trajectory pair, are developed. The first (‘a priori’) approach optimizes the variables of both trajectories at once. The second (‘a...

This research aims at modeling the trajectory followed by the Galileo spacecraft during a variety of flybys about the Galilean moons. The chosen flybys have good Earth’s elevation angles and either low or high closest-approach altitudes, so that the comparison of the two can give relevant insight into the accuracy of the corresponding...

Since December 1990, a number of spacecraft have performed a flyby around Earth in which an unexpected change in velocity has been observed, which has not been explained so far: the so-called flyby anomaly. The effect on the excess velocity has been expressed in an empirical relation by Anderson, which was based on data on 6 such flybys. However...

Around 1610 Galileo Galilei made his discovery of the four large moons orbiting Jupiter which are referred to now as the Galilean moons. The moons Europa and Ganymede attract a significant amount of scientific interest due to potential present subsurface oceans. As consequence, the design of missions to go there and explore the moon system are...

De Smet, S. (author)
The goal of this thesis research has been the improvement of a validated, robust low-thrust optimization tool for interplanetary trajectory design, written during the author's internship. This improved tool has then been applied to design crewed Martian flyby missions. Such a mission is a crucial step within the flexible path scenario for human...
