SPACEMOBILE-SSR03 DEB

SPACEMOBILE-SSR03 DEB is a tracked piece of space debris attributed to United States, launched on 2024-09-12 from Cape Canaveral, Florida on the BlueBird 1-1 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 439 km and 449 km with an inclination of 53.0°. It travels at approximately 27,532 km/h (7.65 km/s), completing one full orbit every 93 minutes — that’s roughly 15.41 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 ~1–3 years. As orbital debris, SPACEMOBILE-SSR03 DEB poses a potential collision risk to operational satellites in nearby orbits and is continuously monitored by the U.S. Space Surveillance Network and other tracking systems.

SPACEMOBILE-SSR03 DEB orbits at an average altitude of 444 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 SPACEMOBILE-SSR03 DEB’s average altitude, there are currently 7,667 active payloads and 157 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1017. This makes it one of the more crowded altitude bands, containing roughly 44% of all active satellites. With an inclination of 53.0°, SPACEMOBILE-SSR03 DEB passes over latitudes between 53.0°N and 53.0°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. United States operates approximately 12,358 active satellites in total, of which 7,342 share a similar altitude band with SPACEMOBILE-SSR03 DEB.
