Type of Appointment (learn more):

Directorate: Technology, Engineering and Quality

Workplace: Noordwijk, NL

Location
ESTEC, Noordwijk, Netherlands

Our team and mission
The Life Support and Physical Sciences Instrumentation Section is part of the Optics, Robotics and Life Sciences Division. Our team works in the area of life support technologies for Human spaceflight, In Situ Resource Utilisation, planetary protection and small payload development for planetary missions, like the Moon and Mars. We do technology development for future missions and support flight projects under implementation as well. In this context we work on In Situ Resource Utilisation processes, with a focus on molten salt electrolysis.

Candidates interested are encouraged to visit the ESA website: http://www.esa.int

Field(s) of activity for the internship
Currently, experiments on oxygen production using molten salt electrolysis are being performed in the ESTEC laboratories.
These experiments will reduce the samples to extract the oxygen and turn the samples into metallic powders, potentially suitable for additive manufacturing. Although these electrochemical experiments can use powder material, a sintered block is preferred. The whole process poses many challenges in terms of material and electrolyte stability, process efficiency and yield, sintering process parameters and optimisation.

In this internship, you are expected to:

• learn about the lunar materials and environment;
• learn about the lunar soil simulants and variations to actual lunar soil;
• learn about existing processes in the field of In-Situ Resource Utilisation (ISRU);
• develop a comprehensive procedure to sinter lunar soil and lunar soil simulant;
• characterise lunar soil simulant before and after sintering by SEM/EDX, XRD, XRF, X-Ray Tomography;
• support the electrochemical experiments extracting the oxygen from the sintered lunar soil simulants.
  

You will also be immersed in the ESA environment which includes space mission preparation and experimentation.
