How we protected the UK and space in June 2025
The National Space Operations Centre is led by the UK Space Agency and UK Space Command in partnership with the Met Office.
June saw reduced levels of space activity with both uncontrolled re-entry and collision alerts at levels below the 12-month rolling average.
All NSpOC warning and protection services functioned as expected throughout the period.
June saw a 14% decrease in the number of objects re-entering Earth's atmosphere, tracked by NSpOC, when compared with the previous month.
Of the 55 objects that re-entered, 50 were satellites and 5 were rocket bodies.
July: 44, August: 89, September: 50, October: 35, November: 47, December: 83, January: 115, February: 129, March: 85, April: 92, May: 64, June: 55
Collision risks to UK-licensed satellites were lower in June with a 19% decline when compared with May, caused by fewer interactions between UK licenced objects and other spacecraft or debris over the previous 30 days.
July: 1,795, August: 2,137, September: 3,041, October: 3,181, November: 2,722, December: 2,142, January: 2,694, February: 2,567, March: 2,588, April: 2,620, May: 1,546, June: 1,259
The in-orbit population increased in June, with a net addition of 235 objects to the US Satellite Catalogue.
July: 28,864, August: 29,669, September: 29,649, October: 29,657, November: 29,816, December: 29,867, January: 29,996, February: 30,027, March: 30,124, April: 30,253, May: 30,504, June: 30,739
The number of Resident Space Objects (RSOs) reported may be subject to small adjustments over time as the way objects are tracked is refined. Figures in this report reflect the most current available data and may differ slightly from those published in previous months
There have been no new fragmentation (break-up) incidents this month.
June saw an increase in space weather activity, particularly geomagnetic events, compared to the previous month
The National Space Operations Centre combines and coordinates UK civil and military space domain awareness capabilities to enable operations, promote prosperity and protect UK interests in space and on Earth from space-related threats, risks and hazards.
