PROGRESS MS-35

PROGRESS MS-35 is an active satellite operated by Russia (CIS), launched on 2026-09-16 from Baikonur Cosmodrome, Kazakhstan on the Progress 7K-TGM No. 465 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 276 km and 295 km with an inclination of 51.6°. It travels at approximately 27,858 km/h (7.74 km/s), completing one full orbit every 90 minutes — that’s roughly 15.96 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is weeks to months. Orbital Radar tracks PROGRESS MS-35 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

PROGRESS MS-35 orbits at an average altitude of 286 km in the lower reaches of Low Earth Orbit, where atmospheric drag is significant and orbital lifetimes are measured in months to a few years. This is the busiest corridor in space — home to crewed spacecraft, rapid-revisit imaging satellites and the densest part of the Starlink constellation. Within ±50 km of PROGRESS MS-35’s average altitude, there are currently 164 active payloads and 17 tracked debris or rocket body fragments — notable neighbours include STARLINK-1036, STARLINK-1048, STARLINK-1068. With an inclination of 51.6°, PROGRESS MS-35 passes over latitudes between 51.6°N and 51.6°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. Russia (CIS) operates approximately 1,536 active satellites in total, of which 15 share a similar altitude band with PROGRESS MS-35.
