News story: How we protected the UK and space in November 2024
November saw a decrease in collision alerts compared to October. More monitorable objects re-entered the Earth's atmosphere month-on-month but we expect the average monthly numbers to decrease as planned re-entry campaigns dwindle.
All NSpOC warning and protection services functioned as expected throughout the period.
November has seen an increase in the number of objects re-entering Earth's atmosphere when compared to the previous month.
Of the 47 objects monitored for re-entry this month, 32 were satellites, 11 rocket bodies, two were pieces of debris and two were classified as unknown objects, likely to a rocket body and a satellite.

Collision risks to UK licenced satellites declined by 14.4% in November.
Although fluctuations are expected month-on-month, this is in-line with the prediction that the monthly average will remain higher than during the first six months of 2024.
We had expected a slight increase in risks due to planned satellite launches, however this does not seem to have materialised as yet.

NSpOC has continued monitoring the aftermath of the Intelsat-33E GEO communications satellite fragmentation which occurred on 19 October. Objects are still being analysed with 18 catalogued objects on Space-Track.org, however, we expect the debris count to be significantly higher over time.
No other fragmentation events were detected or monitored throughout November.
During the reporting period, space weather activity was generally less impactful than last month.
Key space weather events over this reporting period include:
9-10 November
A Coronal Mass Ejection that arrived on the 09 Nov lead to peak G2 Moderate geomagnetic storm conditions on 10 Nov with possible impacts on satellites in LEO, including increased drag, which may have required corrective manoeuvres.
21-22 November
Solar radiation activity was enhanced with a moderate radiation storm observed. Satellites are likely to have experienced a modest increase in Single Event Upsets to electronic systems
Other than these events, geomagnetic activity was largely muted during the month.
There was an increase to the in-orbit population during November, with 213 newly catalogued objects added to the US Satellite Catalogue.
Two of the objects were following launches from the end of October, 220 were from new Starlink satellites ; a further 50 pieces of debris from the LM-6A (CZ-6A) fragmentation which occurred at the beginning of August; and 18 pieces of debris from the fragmentation of INTELSAT-33E satellite on 19 October.
The Chinese G60 constellation increased by 18 satellites from the launch in mid-October

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.
