eSpace leads several innovative space engineering research projects with partners such as Innosuisse and ESA.
They can rely on an intense collaboration with a number of state-of-the-art labs on EPFL Campus with expertise in navigation, materials, robotics, etc. An extended list of these labs can be found HERE.
This project is a collaboration with the HEIG-VD, ClearSpace and the EPFL labs CVLab, ESL and RGLab. ClearSpace will build and operate a commercially viable solution to address failed satellites and prevent the proliferation of debris that could endanger future space operations. The aim of the project is to develop digital AI-based technologies for relative navigation and rendezvous with the targets.
- Relative navigation (estimation of the 6 degree of freedom of a Target object) and radar R&D
- Bring the technology maturity from a TRL 3 to TRL 4 (alpha version for the relative pose estimation and a tested prototype for the radar)

Capture System Concept Validation
ClearSpace is building up a service to remove debris from space. ClearSpace proposes to develop the key technologies needed for a successful capture in this Innosuisse project, to guarantee that a high TRL can be reached quickly and in a most efficient way through the use of the knowhow of the research partners such as CSEM and EPFL labs LSMS and Rehassist. The project increases the TRL from 2 to 4 for the proximity and contact sensing system, and the tentacle control to reach a robust adaptronic capture system design.
Capture Dynamics Simulation Tool which allows:
- Simulating relative movement and dynamics of target/chaser
- Predicting stresses within the capture system
- Simulating the motions of the arms
- Control Algorithms

In-Situ Resource Utilization and Additive Manufacturing
Sustainable and affordable missions to the lunar surface (and beyond) are an aspiration which will need to be supported through a combined scientific and technological progress in in-situ resource utilization (ISRU) and additive manufacturing (AM). The entire lunar surface is covered by an unconsolidated layer of regolith rich in minerals and oxides, constituting several meters of thick soil which could be de-oxidized and yield oxygen and metallic by-product intended for sustainment of human life, propellant and construction of lunar infrastructure.
EPFL lab LMTM has proposed a comprehensive investigation on the printability of these by-products followed by mechanical characterization and the recycling effects of the powder feed-stock and the LPBF processed parts. These parts can be used in structural and load-bearing applications on the lunar surface and cis-lunar missions.

Design for Demise
This thesis project at LPAC and eSpace is focused on the design of a novel composite structure panel that will improve the overall demisability of a spacecraft during its destructive reentry in the atmosphere at the end of its mission. This technology is planned to be integrated into the ClearSpace-1 spacecraft active debris removal mission planned for 2025. This study includes numerical and experimental aero-thermo-mechanical interactions analysis regarding the different types of reentry conditions according to the selected decommissioning strategy.
As part of a Network Partnering Initiative (NPI) supervised by EPFL and ESA, this project aims to get a step forward in the mitigation of reentry surviving space debris threat.
