Uncertainties and robustness with regard to the safety of a repository for high-level radioactive waste: introduction of a research initiative

Published in Environmental Earth Sciences, 2024

The Federal Company for Radioactive Waste Disposal (BGE mbH) is tasked with the selection of a site for a high-level radioactive waste repository in Germany in accordance with the Repository Site Selection Act. In September 2020, 90 areas with favorable geological conditions were identified as part of step 1 in phase 1 of the Site Selection Act. Representative preliminary safety analyses are to be carried out next to support decisions on the question, …

Field-test performance of an ice-melting probe in a terrestrial analogue environment

Published in Icarus, 2023

Melting probes are a proven tool for the exploration of thick ice layers and clean sampling of subglacial water on Earth. Their compact size and ease of operation also make them a key technology for the future exploration of icy moons in our Solar System, most prominently Europa and Enceladus. For both mission planning and hardware engineering, metrics such as efficiency and expected performance in terms of achievable speed, power requirements, …

Ice Transit and Performance Analysis for Cryorobotiv Subglacial Access Missions on Earth and Europa

Published in Astrobiology, 2023

Ice-covered ocean worlds, such as the Jovian moon Europa, are some of the prime targets for planetary exploration due to their high astrobiological potential. While upcoming space exploration missions, such as the Europa Clipper and JUICE missions, will give us further insight into the local cryoenvironment, any conclusive life detection investigation requires the capability to penetrate and transit the icy shell and access the subglacial ocean directly. …

Ice Melting Probes

Published in Handbook of Space Resources, 2023

The exploration of icy environments in the solar system, such as the poles of Mars and the icy moons (a.k.a. ocean worlds), is a key aspect for understanding their astrobiological potential as well as for extraterrestrial resource inspection. On these worlds, ice melting probes are considered to be well suited for the robotic clean execution of such missions. In this chapter, we describe ice melting probes and their applications, the physics of …

Preparing for InSight: Evaluation of the Blind Test for Martian Seismicity

Published in Seismological Research Letters, 2019

In December 2018, the National Aeronautics and Space Administration (NASA) Interior exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission deployed a seismometer on the surface of Mars. In preparation for the data analysis, in July 2017, the marsquake service initiated a blind test in which participants were asked to detect and characterize seismicity embedded in a one Earth year long synthetic data set of continuous waveforms. …

A nodal discontinuous Galerkin approach to 3-D viscoelastic wave propagation in complex geological media

Published in Geophysical Journal International, 2017

A nodal discontinuous Galerkin (NDG) approach is developed and implemented for the computation of viscoelastic wavefields in complex geological media. The NDG approach combines unstructured tetrahedral meshes with an element-wise, high-order spatial interpolation of the wavefield based on Lagrange polynomials. Numerical fluxes are computed from an exact solution of the heterogeneous Riemann problem. Our implementation offers capabilities for modelling …

A Nodal Discontinuous Galerkin Solver for Modeling Seismic Wave Propagation in Porous Media

Published in Poromechanics VI, 2017

This paper is about a nodal discontinuous Galerkin scheme for solving the poroelastic wave equation for materials saturated by one or two immiscible fluids. The presented wave equation is based on Biot’s theory and accounts for macroscopic flow. Using an example of a numerical simulation we show the existence of the third P-wave. The velocity and amplitude of this wave are significantly smaller than the velocities and amplitudes of the first and second P-wave. …

Wave Propagation in Porous Media Saturated with Two Fluids

Published in Transport in Porous Media, 2014

When it comes to geological storage of CO2, monitoring is crucial to detect leakage in the caprock. In our study, we investigated the wave speeds of porous media filled with CO2 and water in order to determine reservoir changes. We focused on deep storage sites where CO2 is in a supercritical state. In case of a leak, CO2 rises and eventually starts to boil as soon as it reaches temperatures or pressures below the critical point. At this point, …
