Top 3 Most Congested Orbital Altitudes

Tracking the regions of space where active satellites and debris density create the highest risk of collision, necessitating missions like SSPICY.

The top 3

  1. Low Earth Orbit (LEO) - 800km: The 800km altitude remains the most densely populated region, containing a high concentration of fragmentation debris from past satellite collisions.
  2. Sun-Synchronous Orbit (SSO) Corridor: Extensively used for Earth observation, this orbit is highly congested due to the standardized paths required for repeat imaging passes.
  3. Geostationary Orbit (GEO) Belt: Though further out, this narrow ring is heavily crowded by communications satellites, leading to strict 'graveyard orbit' disposal requirements.
