Research Fellowship Opportunity in the Directorate of Human and Robotic Exploration Programmes.


ESA is an equal opportunity employer, committed to achieving diversity within the workforce and creating an inclusive working environment. For this purpose, we welcome applications from all qualified candidates irrespective of gender, sexual orientation, ethnicity, beliefs, age, disability or other characteristics. Applications from women are encouraged.


This post is classified F2.


EAC, Porz-Wahn, Germany  


Our team and mission

The European Astronaut Centre's tasks are centered around the “human” component of human spaceflight: astronaut selection, training, medical support and surveillance, as well as support of astronauts and their families during preparation for and during while on space missions to the International Space Station (ISS). 

In order to make the operational experience of EAC available also to other ESA activities, in particular for the preparation of human exploration, EAC has created the Spaceship EAC initiative, to foster innovation and low technology readiness (TRL) concepts and technologies. Within this initiative, the topic of radiation shielding has been investigated, in particular understanding the shielding potential of processed lunar regolith. To date the research has been predominantly carried out with radiation transport code (e.g. FLUKA, GEANT) combined with empirical understanding of regolith material gained from literature, ESA and Spaceship EAC studies. 

This position is made available by the Italian Space Agency (ASI) as part of the ESA-ASI integrated team.

Field(s) of activity/research for the traineeship

You will join the Spaceship EAC team, which is part of the Exploration Preparation, Research and Technology (ExPeRT) team of ESA. The Spaceship EAC team is composed of Research Fellows, Young Graduate Trainees and university interns performing their final year projects within the fields of research and development indicated below. You will mentor some university students and assure an appropriate level of research to be compliant with their university requirements. 

You will also be working on the following activities:

  • Performing applied research in the area of radiation shielding for human spaceflight and exploration, in particular focusing on low TRL concepts and technologies in this domain;
  • Supporting the on-going activities in the development of a strategy for radiation protection of hardware required for a medical system for future human exploration missions.
  • Assuring that the research is coordinated and aligned with 
  • The ESA Exploration Strategy, Space Resources Strategy and the objectives of the Directorate
  • Currently discussed lunar exploration scenarios and related logistical constraints;
  • Relevant on-going R&D activities at ESA or funded by ESA;
  • Supporting the liaison with other ESA teams active in the area of radiation studies relevant to human spaceflight and exploration;
  • Supporting the development of the Spaceship initiatives and related EAC and ExPeRT activities;
  • Actively participating in conferences and meetings to share and promote your knowledge.
