The United Kingdom’s oldest satellite, Skynet-1A, has baffled scientists and space experts alike after it was discovered far off its intended orbit. Originally launched in 1969 to support British military communications, the half-tonne satellite now hovers 22,369 miles above the Americas, far from its original station over East Africa. This dramatic relocation has left experts scratching their heads about who moved it, why, and how.
Piece of Space History Gone Astray
Skynet-1A was a significant technological leap for Britain in the post-Apollo era. Manufactured in the United States by aerospace firm Philco Ford and launched aboard a US Air Force Delta rocket, the satellite was designed to bolster British telecommunications and connect forces across distant regions, such as Singapore. For years, it fulfilled its mission, stationed strategically over East Africa.

However, recent observations reveal Skynet-1A has drifted—or perhaps been deliberately moved—thousands of miles off course. It now resides above the Americas at 105° West longitude, a region known as a “gravity well,” where satellites experience oscillatory movement akin to a marble rolling in a bowl.
Who Moved Skynet-1A?
Scientists are certain of one thing: Skynet-1A did not move on its own. Orbital mechanics and its weight make such a significant shift improbable without human intervention.
Space consultant Dr. Stuart Eves has scoured satellite catalogues, archives, and operational logs but remains unable to determine who might have moved the satellite or when. “Whoever did move Skynet-1A did us few favours,” he said, noting its new location puts it at risk of colliding with other satellites. Since the satellite is defunct but still considered UK property, the country is responsible for any resulting damage.
Plausible Theories
Rachel Hill, a PhD researcher at University College London, offered a potential explanation. She revealed that during periods of essential maintenance at the RAF’s satellite control facility at Oakhanger, the satellite was temporarily handed over to US operators at Sunnyvale, California—also known as the Blue Cube. These “Oakouts,” as they were called, could have provided an opportunity for the satellite to be moved, either intentionally or accidentally.
Others suggest its thrusters might have been fired deliberately during the 1970s, though official records of such a maneuver are missing. Logs indicate the final commanding authority might have rested with the US in 1977, after Oakhanger lost sight of the satellite.
Modern-Day Risk
While Skynet-1A may have become a historical artifact of British space exploration, its current status poses a threat to modern satellites. As Dr. Eves warned, the satellite’s proximity to active orbital traffic increases the risk of a collision.
Professor Moriba Jah from the University of Texas highlighted the dangers of such debris: “Pieces of space junk are like ticking time bombs… When these things explode or collide, they create thousands of pieces of debris, posing further hazards.”

The Ministry of Defence confirms that the UK’s National Space Operations Centre actively monitors Skynet-1A. However, moving the satellite again would require considerable effort, given its defunct state.
