ELECTRON KICK STAGE R/B

ELECTRON KICK STAGE R/B is a spent rocket body associated with United States, launched on 2024-01-31 from RLLC on the Lemur SSA 1-4 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 389 km and 398 km with an inclination of 97.4°. It travels at approximately 27,635 km/h (7.68 km/s), completing one full orbit every 92 minutes — that’s roughly 15.58 orbits per day. Its near-polar, sun-synchronous orbit means it passes over any given point on Earth at approximately the same local solar time, ideal for consistent Earth observation lighting conditions. 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 months to ~1 year. 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 394 km in a sun-synchronous orbit (SSO), a specialised subset of LEO where the orbital plane precesses to maintain a constant angle relative to the Sun. This provides consistent lighting conditions on every pass — essential for Earth observation, weather monitoring and environmental science. Within ±50 km of ELECTRON KICK STAGE R/B’s average altitude, there are currently 1,306 active payloads and 84 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1020. This makes it one of the more crowded altitude bands, containing roughly 7.5% of all active satellites. With an inclination of 97.4°, ELECTRON KICK STAGE R/B passes over latitudes between 97.4°N and 97.4°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet. United States operates approximately 12,413 active satellites in total, of which 1,152 share a similar altitude band with ELECTRON KICK STAGE R/B.
