UK space domain awareness update reported elevated risks and re-entries

Background

  • UK space domain awareness update reported slightly elevated risk levels for UK interests.
  • Uncontrolled re-entry hazards and collision hazards were assessed as more.
  • The National Space Operations Centre's warning and protection services were functioning.
  • 58 objects re-entered Earth's atmosphere, including 51 satellites, 5 rocket bodies and 2 likely debris pieces.
  • Collision risk to UK-licensed satellites was 16%, below the 12-month rolling average.

What happened

The record describes a UK space domain awareness update in which risk levels for UK interests were slightly elevated. Uncontrolled re-entry hazards and collision hazards were assessed as more. NSpOC warning and protection services were functioning.

What we know

UK interests were assessed at slightly elevated risk levels. Both uncontrolled re-entry hazards and collision hazards were rated as more, and NSpOC warning and protection services were functioning.

The NSpOC monitoring figure for objects re-entering Earth’s atmosphere was 7 percent. The re-entered total was 58 objects. The counts were 51 satellites, 5 rocket bodies, and 2 likely pieces of debris.

Collision risks to UK-licensed satellites were 16 percent. Their status was below the 12-month rolling average.

The in-orbit population increased, and the US Satellite Catalogue count was 163. The record includes 1 fragmentation incident in Low Earth Orbit, while debris assessment was ongoing.

Space weather activity was lower. Solar radiation and geomagnetic storms were both very limited.

The National Space Operations Centre brings together the UK’s civil and military space domain awareness capabilities and coordinates them.

Why it matters

The update shows collision hazards and uncontrolled re-entry hazards assessed as more, with UK interests at slightly elevated risk. For lunar-industry readers, this matters because space domain awareness and hazard monitoring shape the operating environment for space assets.

The functioning of the National Space Operations Centre’s warning and protection services matters because it brings together and coordinates the UK’s civil and military space domain awareness capabilities.
