OMAR – On orbit manufactured spacecraft

The objective of this activity is to assess the system level and design impacts of optimising a satellite design for on-orbit manufacturing and assembly, as well as preparing it to be refurbished, reused or recycled on orbit afterwards, and to identify the technologies needed.

Analysis of space debris recycling potential to supply raw materials for construction on the Moon

As on Earth, space debris should not only be seen as a threat. Instead, the value of waste as a recycled good should be understood. On Earth, this potential is already fully recognised. The German recycling industry alone generates more revenue than the entire European space industry. Nevertheless, this treasure was never lifted in space.

Preliminary design of on-orbit manufacturing of large antenna reflectors

This study aims to carry out the conceptual design of a large-parabolic-antenna reflector that is manufactured and assembled on-orbit.

Through its Clean Space initiative, ESA has been devoting an increasing amount of attention to the environmental impact of its activities, including its own operations as well as operations performed by European industry in the frame of ESA programmes. In its Technology Strategy, ESA identified 'Inverting Europe’s contribution to space debris by 2030' as one of the four technology development targets.

Basalt fibre reinforced geopolymer made from lunar regolith simulant

The objective of the study was to investigate the performance and shielding abilities of lunar regolith-based geopolymer when reinforced with basalt fibres and cured under environmental conditions of the lunar surface. The geopolymer building materials should be suitable for
3D-printing on the Moon. Since there is a very limited supply of water on the moon, the study also focuses on lunar geopolymers with a reduced amount of water in the recipes, without the need for raw materials that cannot be resourced locally on the Moon.

Additive manufacturing of functionally graded ceramics with in-situ resources

In this activity, lunar regolith simulants were characterised based on their thermal behaviour, particle size distribution and composition, in order to inform the choice of consolidation method for functionally graded materials (FGMs) – powder characterisation results are provided in the 'conference paper' deliverable.

Firstly, an extensive literature review study (deliverable 'Literature Review') identified Digital Light Processing (DLP) and Spark Plasma Sintering (SPS) as promising consolidation techniques.

Passive damped deployment of full composite structures

This study aimed to demonstrate the feasibility, use and functionality of carbon fibre-reinforced flexible epoxy (CFRFE) materials for self-deployable space structures (such as deployable tape-spring hinges) by designing, simulating, manufacturing, testing and correlating a classic (100% carbon fibre-reinforced plastic -rigid resin- CFRP) deployable tape-spring hinge and a CFRFE deployable tape-spring hinge and compare their mechanical and dynamic behaviours.

Design of space hardware using a CDF like methodology (AMCDF)

The project aimed to establish a structured approach to an optimised part or component by applying Concurrent Design methods. It intended to incorporate all necessary disciplines and competencies that are required for a potential spacecraft part. Within the activity, advanced manufacturing included various novel techniques, not only additive manufacturing. It means that the Concurrent Design approach was developed for the engineering of units to be built with a broad range of advanced manufacturing technologies.

Robotic manufacturing of fibrous structures in space

Motivation: This study aimed to develop promising robotic fabrication methodologies for a fibre-based in-situ robotic fabrication process, for application in a lunar habitat as an alternative to existing additive manufacturing methodologies. Previous work has verified that fibre composite fabrication processes are capable of a high degree of automation and structural performance.

GreenSat

Due to the harsh nature of outer space, stringent requirements and performances are required from space systems. Thanks to evolving environmental awareness and the building up of a knowledge base at ESA, we are becoming more wary of the environmental impact of space activities on Earth. Through the GreenSat project, ESA wants to evolve from the assessment to reduction of environmental impact through redesigning an existing satellite mission. The project allows ESA to check the feasibility of implementing ecodesign in the development of space missions.

REACH into LCA – Integration of REACH and CRMs into the Life Cycle Assessment framework

For the REACH assessment, the proposed method relies on both ESA’s existing Life Cycle Assessment (LCA) framework and the Materials & Processes Technology Board (MPTB) database. Then, the method was structured through three steps:

  • Firstly, a commonality was found between the LCA and MPTB databases: ECSS classes, which help define small groups of materials defined as 'clusters', are used to 'bridge the gap' in terms of level of precision between the LCA model of a space system and the MPTB database;
