Intern in Space Transportation Technology Coordination, Reusable Space Transportation Systems

Intern in Space Transportation Technology Coordination, Reusable Space Transportation Systems- **Job Requisition ID**:19908- **Date Posted**:1 November 2025- **Closing Date**:30 November 2025 23:59 CET/CEST- **Publication**:External Only- **Type of Contract**:Intern- **Directorate**:Space Transportation- **Workplace**:Paris, FR**Location**
ESA Headquarters, Paris, France
** Our team and mission**-
-The Directorate of Space Transportation (D/STS) mission is the European independent access to and freedom in space. The Directorate's main activities are related to the:
-- development and exploitation of Ariane and Vega launch systems;
- maintenance and upgrading of the European Space port (CSG) in Kourou, French Guiana;
- development of new launch and space transportation systems, including reusable demonstrators.
-Within the Directorate, the Space Transportation Technology Coordination Office (STS-CT), part of the Chief Technical Advisor Office (STS-C) is involved in selected critical preparatory activities with the industry for enabling critical informed decisions by Member States on developing future European transportation capabilities, and has the mission of fostering transversal technology synergies across STS and ESA, seeking shared and optimised technology roadmaps for Europe.-
** Field(s) of activity for the internship**-
-** Topic of the internship: Composite Structures for Reusable Space Transportation Systems**-In the framework of this internship, you will perform analysis cross-checks to support the design optimisation of reusable space transportation systems, with a focus on launchers' primary structures such as composite stages, tanks, interstages and fairings, with the specificities of reusability (e.g. service life, detection of defects, delamination, repairability). Therefore, your internship will focus on the design optimisation of several structural elements of different reusable launch and/or re-entry vehicle architectures employing composite materials. The objective is to investigate the design trade-offs and performance implications, with particular attention to structural components delamination for reusability.
More specifically, your tasks will include:
-- review existing expendable and reusable space transportation systems configurations;
- define reference missions and baseline reusable vehicles parameters (e.g., vehicle mass, structural loads);
- identify possible composite structural solutions for the different elements (e.g., stages, tanks, interstages, fairings);
- perform conceptual design optimisation, mass estimation and structural sizing of the vehicles;
- assess the impact of reusability on key design parameters and loads;
- provide advantages and disadvantages of the investigated composite structural solutions.
