Revolutionizing Satellite Longevity: UK Facility to Test In-Orbit Satellite Servicing

In an effort to combat the increasing threat of space debris and enhance satellite longevity, the UK Space Agency has announced a significant investment of almost £3.5 million into technological advancements. This initiative promises to contribute to space sustainability by enabling the repair and refuelling of satellites directly in orbit.

Central to this endeavor is a £2 million upgrade to the Westcott Space Cluster’s Satellite Applications Catapult’s In-Orbit Servicing and Manufacturing (IOSM) facility. This funding will usher in a new era of capabilities for UK companies, providing a testing ground for a wide array of in-orbit operations which include repairs and refuelling. The UK plans to leverage its expertise and strategically position itself in the rapidly growing IOSM market, expected to be worth £11 billion by 2031.

Grounded in the UK’s National Space Strategy, the investment also aligns with collaborative efforts to establish space sustainability standards. The upgraded IOSM testing grounds boast features such as dynamic tracking and a gravity off-load system to accurately mirror the harsh conditions of space, while digital twin technology will enhance virtual simulations.

In addition to the improvements at the IOSM facility, the package includes nearly £1.5 million for studies into the feasibility of satellite refuelling in space, aiming to breathe new life into aging satellites and thus minimize space debris.

Three contracts have been awarded for the research into refuelling technologies, including adaptations to existing debris-removal spacecraft and development of innovative interfaces and solutions for fuel transfer in space. These partnerships bring together entities like Astroscale, ClearSpace, and Orbit Fab with aerospace leaders such as Airbus Defence & Space and MDA, signifying a concerted push towards more sustainable space practices.

This strategic funding underscores the UK’s commitment to leading the charge in space sustainability, setting a global precedent for responsible space exploration and utilization.
