The company stands out for its commitment to sustainability, using bio-propane as fuel, which significantly reduces carbon emissions compared to traditional rocket propellants. Orbex has secured launch contracts and is working toward first orbital flights from Space Hub Sutherland.

The Scottish Space Hub

Scotland has emerged as a surprising powerhouse in the UK space landscape. The country manufactures more small satellites than any other European location and hosts a growing cluster of space companies in Glasgow and central Scotland. Combined with the development of multiple spaceports in the Scottish Highlands and islands, Scotland is positioning itself as a vertically integrated space hub covering everything from satellite production to launch.

Virgin Orbit Legacy

Virgin Orbit attempted to bring horizontal air-launch capability to the UK through its partnership with Spaceport Cornwall at Newquay Airport. The January 2023 launch attempt, the first orbital launch from UK soil, ended in failure when the rocket experienced an anomaly. Virgin Orbit subsequently filed for bankruptcy, but the effort highlighted UK ambitions for sovereign launch access and paved the way for continued spaceport development at Cornwall and other sites.

Defense, Intelligence, and National Security Space

The UK maintains a significant defense and intelligence space presence. The Ministry of Defence operates the Skynet military satellite communications system, which provides secure communications to UK and allied forces globally. The latest generation, Skynet 6, is being developed by Airbus Defence and Space to deliver enhanced capacity and resilience.

The UK's defense space strategy emphasizes space domain awareness, resilient satellite communications, and intelligence capabilities. The Defence Space Command, established in 2021, coordinates military space operations across the armed forces. The country also participates in the Five Eyes intelligence-sharing alliance, which extends into space-based signals intelligence and Earth observation.

Several UK companies support the defense space sector, including CGI, BAE Systems, and QinetiQ, which provide satellite ground systems, data analytics, and space situational awareness capabilities.
