The National Space Operations Centre (NSpOC) has released its monthly report for May 2026, indicating a mixed picture for the safety of UK interests in space and on Earth. While overall risks from space-related threats saw a month-on-month reduction, particularly in uncontrolled re-entries and space weather activity, a notable increase in collision alerts for UK-licensed satellites underscores the growing complexities of orbital management.
During May, the NSpOC, which coordinates the UK's civil and military space domain awareness, monitored a 29% decrease in objects re-entering Earth's atmosphere compared to April. A total of 48 objects re-entered, comprising 43 satellites, four rocket bodies, and one piece of suspected debris. All NSpOC warning and protection services were fully operational throughout the period, ensuring continuous monitoring and response capabilities.
However, the report highlighted a concerning trend regarding potential collisions. Risks to UK-licensed satellites increased by 8% in May compared to the previous month, surpassing the 12-month rolling average. This rise in alerts coincides with a significant expansion of the in-orbit population, with a net addition of 268 objects to the US Satellite Catalogue during May. This continuous growth in Resident Space Objects (RSOs) presents an ongoing challenge for avoiding orbital incidents.
On a more positive note, May saw a considerable reduction in space weather activity. The NSpOC reported significantly lower levels of activity compared to April, predominantly consisting of minor geomagnetic storms. This relative calm in the space environment contributed to the overall decrease in risk to UK interests.
The NSpOC's role is crucial in safeguarding UK interests, promoting prosperity, and protecting against space-related threats and hazards. The centre's ability to combine and coordinate diverse space domain awareness capabilities is vital as the number of objects orbiting Earth continues to expand, demanding constant vigilance and sophisticated analysis to prevent potential catastrophic events or disruptions to essential services.
