ES-2204 - PhD Student
ES-2204 - PhD Student in precision size classification for Luna Soil
Are you passionate about space resources? So are we!
The return of human and robotic exploration missions to the Moon in the near future will mark a new era of space exploration. Future missions will rely on resources found in space, for example oxygen from lunar soil, to provide consumables for refuelling, to support human life and to build the infrastructure required. The development of equipment, processes and systems to characterise, extract and use materials produced from space resources is a dynamic and exciting field. This is what we do at ESRIC.
The European Space Resources Innovation Centre (ESRIC) is a joint initiative of the Luxembourg Space Agency (LSA), the European Space Agency (ESA) and the Luxembourg Institute of Science and Technology (LIST). ESRIC was formed in 2020 with an aim to become an internationally recognized centre of expertise for scientific, technical, business and economic aspects related to the use of space resources for human and robotic exploration, as well as for a future in-space economy.
As a new initiative, ESRIC has an ambitious vision in an evolving international environment. Being part of a growing team and contributing to building successful activities with ESRIC’s partners is common to all of ESRIC’s positions.
You’d like to contribute as a researcher? Join us!
As part of the development of ESRIC’s research capabilities, we have received funding from the FNR (Luxembourg’s national funding agency) to build a new research team under the PEARL programme. This multimillion Euro flagship funding will support several postgraduate and postdoctoral researchers in novel space resources topics. The programme, SolSR (Solutions for the Sustainable and Responsible use of Space Resources), has a strong focus on enabling technology, circular economy and environmental impact for space resource utilisation. You will join this team, developing world-leading research expertise in a supportive environment.
Aufgaben und Einsatzfelder
How will you contribute?
Many processes have been proposed to produce usable materials from the lunar soil (regolith), including extraction of oxygen using reduction or electrolysis, additive manufacturing, and construction using sintering. All of these processes will require a controlled feedstock from the excavated regolith that provides a defined particle size distribution. Separation and sorting of lunar regolith by size (beneficiation) is an area of space resources that has received relatively little attention, but that is a critical enabling technology.
In this project, you will design, test and build a regolith size classification system for the Moon. You will explore the limits of precision for separation of fine particles (e.g. <50 micron) for small samples and propose novel methods for separation of particles by size that could be used for small sample sizes on early prospecting missions. Current suggestions are often based on sieves and screens, which have significant limitations under lunar environmental conditions and with dry, abrasive particles. Possible techniques to explore in this project include vibrational segregation. You will evaluate critically potential candidate technologies and use this as a basis for your experimental system. You will use advanced imaging (e.g. XCT) and/or high speed imaging to analyse the efficiency of the system and to optimise experimental conditions. Simulations, e.g. using DEM, may be applied to further improve the design. You will explore the effects of particle size and shape using idealised particle mixtures, in addition to using lunar regolith simulants. The goal of this research is to generate operating guidelines for small-scale particle size classification technology and to produce a concept that can be developed as a payload.
As a PhD student within LIST, you will have the following responsibilities:
- Follow and advance a research plan in agreement with your supervisor(s)
- Know the state of the art on the research topic of the thesis to be undertaken
- Manage the daily research work allowing you to deepen your knowledge of your research field
- Contribute to the preparation of progress reports on research for funding bodies and key stakeholders as required
- Contribute to the overall activities of the RDI group and department as required
- Actively collaborate with other researchers (ESRIC or external) and participate in group meetings, meetings with academic and non-academic collaborators
- Contribute to the drafting and submitting of papers to peer reviewed journals and conference proceedings
- Contribute to the creation of intellectual property rights (patents, licences, etc.)
- Prepare posters and presentations for conferences
- Present your work at local, national and international meetings with guidance and prior internal review
- Defend your thesis within the required time frame
