Fishing on Europe: Dynamics of the Jovian moon and its subsurface ocean

Huibregtse, J.N. (author)

The interior of Europa, one of the moons in the Jovian system, is still mainly unknown. There are, however, indications that below an icy outer layer a subsurface ocean is present. Moreover, it has been estimated that in total the ice and ocean are between 80 and 170 kilometers thick. Concerning the thickness of the ice layer, there exist two...

Automatic and fast generation of sub-optimal and feasible low-thrust trajectories using a boundary-value pseudo-spectral method

De Vogeleer, B.J.T.V. (author)

Some problems in Astrodynamics, such as the ones posed in the several editions of the Global Trajectory Optimisation Competition, include both a combinatorial and a trajectory optimisation problem. The combinatorial problem consists of finding the sequence of a fixed number of asteroids that will allow to find the optimal trajectory. The...

Weak capture and the weak stability boundary: An investigation into the restricted problem of three bodies

Kumar, K. (author)

Weak capture in the restricted problem of three bodies refers to transitory motion between the primaries. Such behavior has interesting applications in space mission design, notably, in finding optimal transfer trajectories that surpass the performance of traditional Hohmann transfers. The Weak Stability Boundary (WSB) is a mathematical set that...

Surface motion modeling for the southeastern Carpathians: Processing and analysis of GPS observation data from the Vrancea seismic region in Romania

Broerse, D.B.T. (author)

The SUBDUCT (Surface Behavior and Dynamical Units of the Southeast Carpathians Tectonics) research program, in which the TU Delft participates, aims to model the surface kinematics of a 350 x 350 km wide area around the Vrancea seismic region in Romania by means of GPS observations. The goal of the project is to relate surface motions to the...

On the integral-conservative numerical solution of few-body gravitational problems: With applications to capture trajectories

Verzijl, C.J.O. (author)

On the design and implementation of integral-conservative numerical integration schemes for few-body problems in astrodynamics. Focuses on exact and approximate energy and angular-momentum integrals in the Jacobi 3-body problem, and related Jacobi-type integrals in the circular restricted 3-body problem and a 4-body model for ballistic lunar...

Validation of Oceanic Mass Changes derived from GRACE Gravimetry: A comparison with independent data from Bottom Pressure Recorders in the Southern Ocean

Rietbroek, R. (author)

The satellite mission GRACE (Gravity Recovery and Climate Experiment) provides monthly solutions of the global gravity field of the Earth. Temporal variations in gravity reflect mass redistributions over the Earth. Those mass movements are caused by physical phenomena such as ice sheet dynamics, accumulation of hydrological masses over land, the...

3D temperature modeling for the South China Sea using remote sensing data

Twigt, D.J. (author)

The South China Sea's (SCS) seasonal, large-scale temperature cycle is governed to a large extend by the monsoon. This phenomenon modulates the large-scale circulation, transport and mixing as well as the exchange processes with the Pacific Ocean and the East China Sea. Also, significant variations in net surface heat flux will contribute to the...

Impact of the space and satellite environment on the optical path differences of Darwin

Sterken, V.J. (author)

ESA's space interferometry mission Darwin will make use of optical delay lines (ODL) to help control the optical path differences (OPD) between the satellites to the nanometer level. In order to determine the required ODL control bandwidth, this study investigates the order of magnitude of the high-frequency (> 1 Hz) disturbance forces, and...
