IOS Mission and Maturation Phase Proposal – In-Orbit Refuelling Assessment

During this Phase 0 maturation study, ASUK, with the support of Thales Alenia Space (TAS), Nammo, MDA and GMV, performed a programmatic, business and technical assessment of a future low-Earth orbit (LEO) refuelling mission. The mission concept proposes developing and demonstrating core technologies in a preliminary service offering to enable a commercial in-orbit refuelling service. Such a service will swiftly redefine how satellites are designed and operated, launching a dynamic and sustainable in-orbit ecosystem with significant potential.

IOS Mission Proposal and Maturation Phase

In the frame of an In Orbit Servicing Maturation Phase (IOSMP) contract, this maturation study has been realised on the START-€ solution which is proposed to extend the lifetime of geostationary orbit (GEO) communication satellites. The START-€ servicer spacecraft will first demonstrate on a GEO communication satellite its ability to perform the critical operations related to its mission, before proceeding with several commercial life extension missions by capturing and taking the AOCS control of aged client spacecraft.

Visualising injector-coupled combustion instability in lox/H2 flames
A recently completed technology activity (ESA-IPL-PTM-sfe-st-LE-2015-510) attempted to systematically test the capability of numerical tools in predicting injection-coupled combustion instability in lres. This type of instability is caused by the coupling of the acoustic pressure field in the combustion chamber to acoustic resonance modes in the injectors. The results demonstrated unsatisfactory predictive capability due to challenges in accurately capturing key aspects in the modelling, such as the distribution of fluid properties throughout the injector-chamber system.

ENCORE – In-Orbit Servicing of an Operational Spacecraft

The market for life‐extension services for geostationary orbit (GEO) satellites is expected to remain healthy for the foreseeable future: over the last 20 years, an average of 22 new GEO satellites were launched per year. In total, ClearSpace expects there will be 370 potential client satellites that will reach their end of life due to the limited fuel they have remaining over the 2026–2041 period. ClearSpace believes a strong market penetration rate is feasible, as more than 30% of all the potential satellites belong to just seven satellite operators.

Preparation of enabling space technologies and building blocks: GNC and Robotic arm combined control

The research activity aimed at the development of relative navigation and combined control algorithms for controlling an autonomous spacecraft equipped with a redundant manipulator used to capture a target spacecraft. Numerical testing of the GNC solution proposed was performed through an accurate and realistic simulation tool. The GNC system shows good performance for all the considered scenarios, although SC3 is the most challenging due to the high rotation rate of the target. The error budget analysis has highlighted the major sources of errors.

Magnetic Powder as Propellant in Electrostatic Thrusters (MPEP)

The main objectives of this project were to develop a thruster prototype based on magnetic powder electrostatic propulsion and to test it in vacuum with direct thrust measurements. The aim was to check the robustness of the concept and to measure and calculate important performance parameters such as thrust and specific impulse, to allow a comparison with other thruster technologies. This project demonstrated for the first time the feasibility of electrostatic propulsion based on powder emission.
