Increased Space Activity Observed in December
December marked a significant rise in space activities, with a notable uptick in uncontrolled atmospheric re-entries and collision alerts compared to November. However, the influence of space weather on infrastructure was less pronounced during this period.
Re-entry Analysis
Data from the National Space Operations Centre (NSpOC) indicates a 21% rise in the number of objects re-entering Earth’s atmosphere in December, relative to the previous month. A total of 52 objects re-entered, comprising 39 satellites, 11 rocket bodies, and two suspected debris pieces.
Monthly re-entry statistics from January to December.
Collision Avoidance Analysis
There was a slight increase in collision risks for UK-licensed satellites in December, with a 7% rise compared to November. This escalation is attributed to a higher frequency of interactions between UK-licensed satellites and other objects in orbit.
Number of collision alerts from January to December.
Registered Space Objects (RSOs) Analysis
The population of in-orbit space objects showed growth in December, with the US Satellite Catalogue recording a net increase of 383 new objects. This development reflects the ongoing expansion of commercial and government space initiatives.

Fragmentation and Space Weather Analysis
One notable fragmentation incident was reported in December involving a satellite operating in Low Earth Orbit. Investigations are underway to ascertain the extent of debris generated from this event. Conversely, December saw a reduction in space weather activity, with fewer geomagnetic storms and solar flares, alongside an absence of solar radiation storms.
Background
The ongoing activities monitored by the NSpOC are essential in ensuring the safety and sustainability of space operations. Increased satellite launches and the growing presence of debris in low Earth orbit necessitate vigilance in tracking these objects to mitigate potential hazards.
The National Space Operations Centre plays a crucial role in coordinating civil and military efforts in space, aiming to enhance UK interests and promote security from space-related threats.
