Through its Clean Space (CS) 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. On-orbit manufacturing and recycling is a concept that has been gaining momentum in the past years. A number of isolated technology...

Mr Joerg Kreisel (JKIC)23/09/2021, 15:10Debris removal and servicing
Space Sustainability has become an important topic over the last two decades fueled by the debris issue and an increasing number of space infrastructure elements. Besides servicing and debris removal partly sharing technologies, new system solutions are proposed to broaden the scope of space mission, to improve their economics and to make space sustainable in the long-term, also regarding...

Mr Declan Jonckers (TU Braunschweig, Institut für Raumfahrtsysteme)23/09/2021, 16:10Debris removal and servicing
Large format, on-orbit additive manufacturing (AM) and assembly is actively being considered as a modular solution that facilitates resource efficient manufacturing, operations, and servicing in space. Customizable structures that can be manufactured in space bring a myriad of benefits that can significantly contribute towards sustainable space missions. To realize this, a novel AM approach to...

Mr Andrew Bacon (Space Forge)23/09/2021, 16:40Debris removal and servicing
The opportunity for in-space manufacturing is significant. The potential for in-space manufacturing to create new materials, composites, and alloys by leveraging the conditions of the space environment is high. As is, the ability to use in-space manufacturing technologies for future exploration and In-Situ Resource Utilisation (ISRU) needs.
However, in-space manufacturing is limited due to...

Through its Clean Space (CS) initiative and to fully benefit from the removal of constraints linked to on-ground manufacturing and launcher requirements, ESA has set up the OMAR (On-orbit Manufacture, Assembly & Recycle) initiative. It is a system approach aiming to give an overview of the most interesting applications, to map the state-of-the-art and to derive a roadmap for the critical...

Laszlo Szegedi (Admatis Ltd., Miskolc, Hungary)24/09/2021, 09:55Debris removal and servicing
In terms of design for removal, passive technologies installed on the target satellite may potentially ease identification, tracking and pose estimation of the target. From far to close rendezvous, planar distributed 2D markers can be used for such purpose, while for the last moments of the rendezvous, up to capture, a single 3D marker is required to perform pose estimation. Installing LRRs on...

In the last years many space agencies and national entities have raised the problematic of introducing and/or already introduced Space Debris Mitigation (SDM) requirements within the design and development of the next generation of space missions, LEO scenarios/platforms in particular. The introduction those SDM requirements has a not negligible impact both at system and sub-system level on...

Thermal one-way effect Shape Memory Alloy (SMA) actuators are a lightweight, robust and cost effective alternative to conventional actuators like pyrotechnics or electromagnetic actuators. Parts machined from SMA could be pseudo-plastically deformed in cold state, later they return to their previously machined shape by simply heating them up to their phase transformation temperature. During...

An Vercalsteren (VITO)EcoDesign for Space
CO2M is a mission to measure and identify hotspots of anthropogenic CO2 emissions. In order to assess, and if possible improve, the environmental impact, that designing, building and testing the satellites for CO2M has, a life cycle assessment is performed regularly throughout the development of the mission. This LCA covers two aspects:

Mark Fittock (OHB)Managing the end of life
OHB’s key challenges for LEO End of Life are in the selection of the best spacecraft design options available to fulfil the requirements of the missions at stake. The primary decision to be reached is whether the re-entry requirements can be met through controlled or uncontrolled re-entry. For some missions, the selection is clear, however, between these lie a trade-off space whereby either...

Dr Martin Dunstan (University of Dundee)Debris removal and servicing
Space Debris Removal applications will require precise navigation and orbital manoeuvres so may include a variety of onboard sensors to support different types of autonomous guidance systems. Vision and LiDAR-based Guidance Navigation and Control (GNC) systems are well-established for space applications including planetary landers, small-body approach and landing, hazard detection for precise...
