Orbit Fab and Thales Alenia Space have launched a joint project to explore the possibilities of refueling electric-propulsion satellites directly in orbit. Supported by the U.K. Space Agency, this initiative is part of a strategy to develop European space infrastructure and create reusable systems. This is reported by Ixbt.com .
The project, called Refuelable Electric Engine Flatsat, will be carried out by both companies' UK teams. The partnership focuses on integrating the RAFTI (Rapidly Attachable Fluid Transfer Interface) developed by Orbit Fab with Thales Alenia Space electric engines, specifically xenon Hall thrusters.
The RAFTI interface is a specialized port designed to connect satellites to orbital depots or service vehicles. Previously, this technology was approved by the U.S. Space Force for use on military satellites, including demonstration missions for hydrazine transfer.
To test the technology, the project participants will build a "flatsat" — a specialized ground test bench. This stand will allow for verifying satellite component performance, practicing fluid transfer processes, and exploring refueling concepts for electric-propulsion spacecraft before a flight model is assembled.
This development aims to extend the service life of satellites and expand the maneuvering capabilities of spacecraft. This area is currently becoming one of the most important vectors for the development of the European space sector.
