ELECTRON KICK STAGE R/B

ELECTRON KICK STAGE R/B is a spent rocket body associated with United States, launched on 2025-03-15 from RLLC on the QPS-SAR-9 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 553 km and 559 km with an inclination of 42.0°. It travels at approximately 27,309 km/h (7.59 km/s), completing one full orbit every 96 minutes — that’s roughly 15.04 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Spent rocket bodies like ELECTRON KICK STAGE R/B are among the largest pieces of uncontrolled space debris and are priority targets for collision avoidance manoeuvres and future active debris removal efforts.

ELECTRON KICK STAGE R/B orbits at an average altitude of 556 km in the core of Low Earth Orbit, the most heavily utilised altitude band. The balance of moderate drag (limiting debris accumulation) and short signal path (enabling low-latency links and high-resolution imaging) makes this regime the default for most commercial and government missions. Within ±50 km of ELECTRON KICK STAGE R/B’s average altitude, there are currently 3,199 active payloads and 393 tracked debris or rocket body fragments — notable neighbours include STARLINK-1184, STARLINK-1276, ONEWEB-0050. This makes it one of the more crowded altitude bands, containing roughly 18.3% of all active satellites. With an inclination of 42.0°, ELECTRON KICK STAGE R/B passes over latitudes between 42.0°N and 42.0°S, covering the tropical and temperate zones where most of the world’s population resides. Low-to-mid inclination orbits are efficient to reach from equatorial and mid-latitude launch sites. United States operates approximately 12,413 active satellites in total, of which 2,620 share a similar altitude band with ELECTRON KICK STAGE R/B.
