UK military satellite launches to boost space power
The UK military has successfully launched its first dedicated Earth-imaging satellite, named Tyche. This washing machine-sized spacecraft is designed to capture high-resolution images of the Earth, capable of identifying battlefield troop positions and vehicles. While Tyche serves as a demonstrator, it is expected to pave the way for a network of satellites equipped with various sensors over the coming decade. Some of these future satellites may even be capable of penetrating cloud cover and eavesdropping on radio transmissions.
Tyche was launched aboard a SpaceX Falcon rocket from California, with lift-off occurring at 11:56 AM local time (19:56 BST). The satellite will orbit the Earth at an altitude of approximately 500km and is expected to remain operational for at least five years.
Historically, the UK's Ministry of Defence (MoD) has relied on alliances, particularly with the United States, to access surveillance and reconnaissance imagery. While the MoD has funded projects in the UK commercial sector before, Tyche represents the first wholly owned imaging capability by the British military.
Commissioned by UK Space Command and built by Surrey Satellite Technology Ltd (SSTL) in Guildford, the 160kg satellite uses optical wavelengths to capture images in the same light visible to the human eye. It can capture 5km-wide spot scenes on the ground, with a best resolution of 90cm, which is sufficient for the British military's general needs, even though it is not as advanced as some classified U.S. satellites capable of resolving features as small as 10cm.
Tyche's development stems from the 2021 Space Command Paper and the 2022 Space Defence Strategy, which committed the previous UK government to invest £970 million over ten years in a program known as Intelligence, Surveillance, Target Acquisition, and Reconnaissance (ISTARI). The goal is to establish a sovereign constellation of military and national security satellites, equipped with technologies like radar sensors that can see through all weather conditions and at night—capabilities that have proven crucial in conflicts such as the one in Ukraine.
"This is the start of a journey," said Maj Gen Paul Tedman, commander of UK Space Command. "The space defence strategy lays out how we're going to become a meaningful space power by 2030. We're hoping to see many more launches of satellites in the coming months and years. Tyche is absolutely the beginning of that.”
SSTL is optimistic about securing more defense contracts, both within the UK and internationally, as many countries establish their own space commands. The Tyche contract, valued at £22 million, showcases SSTL's capabilities in delivering defense missions.
One notable feature of Tyche is its propulsion system, which uses water to maneuver the satellite. The water is heated to produce superheated steam, providing thrust for station-keeping. Tyche carries 10 liters of water, which is expected to provide five to seven years of operational life.
Despite the ambitious goals of the ISTARI program, the UK's Defence Space Strategy has faced criticism. The Commons Defence Select Committee previously described the UK as a "third-rank space power" and expressed concerns about the MoD's ability to deliver major projects on time and within budget. With a new government now in place and a review of UK defense needs and spending underway, policy experts like Julia Balm from King's College London are watching closely to see if the country's commitment to becoming a space power remains steadfast.
"I think if there's anything negative on ISTARI or there are any cutbacks when it comes to things that have already been committed in strategies, then that's just indicative of the UK's inability to deliver any sort of long-term or large-scale project. And it also doesn't really hold a good message about the UK being committed to growing as a space power," Balm told BBC News.
