UK and Space Safeguarded in April 2024

The National Space Operations Centre (NSpOC) protects UK interests in space and on Earth and works with international partners to ensure space remains safe and accessible to all.

Summary

Overall risks to UK interests in space and on Earth from space-related threats, risks and hazards were lower in April than March. We are anticipating an increase in objects re-entering the Earth's atmosphere in May but expect many of these to burn-up in the atmosphere.

Uncontrolled Re-Entry Early Warning

There were 12% fewer objects re-entering the Earth's atmosphere in April than March. We monitored 22 uncontrolled re-entries in April to protect the UK and UK Overseas Territories as well as support our international partners.

In-Space Collision Avoidance

We warned UK-licensed satellites of 1,899 potential collision risks in April allowing operators to take critical manoeuvre actions to avoid potentially catastrophic collisions. This represents a 0.2% reduction in potential collisions involving UK-licensed satellites compared to March.

Fragmentation incidents

We investigated two potential fragmentation incidents in April including an incident involving a 24-year-old rocket body that experienced 'out-gassing' and significantly increased its rate of spin.

Out-gassing occurs when materials designed to contain gas or fuel fail which results in gas escaping. Neither fragmentation incident posed a substantive risk to UK licenced satellites.

Space weather

The Met Office issued ten critical space weather alerts in April. This represents a 60% reduction from March.

Number of Objects in Space

There were 277 additional objects recorded in space in April taking the total number to 28,752. These numbers do not include small items of debris and therefore the total number of actual space objects is much higher.
