LEMUR 2 DEVERILL-M-T

LEMUR 2 DEVERILL-M-T is an active satellite operated by Spire Global (United States), launched on 2023-07-18 from RLLC on the Electron 39 Rideshare launch. It orbits in Low Earth Orbit (LEO) at altitudes between 436 km and 444 km with an inclination of 99.4°. It travels at approximately 27,540 km/h (7.65 km/s), completing one full orbit every 93 minutes — that’s roughly 15.42 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 ~1–3 years. Orbital Radar tracks LEMUR 2 DEVERILL-M-T in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

LEMUR 2 DEVERILL-M-T orbits at an average altitude of 440 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 LEMUR 2 DEVERILL-M-T’s average altitude, there are currently 8,933 active payloads and 135 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 50.1% of all active satellites. With an inclination of 99.4°, LEMUR 2 DEVERILL-M-T passes over latitudes between 99.4°N and 99.4°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 12,673 active satellites in total, of which 8,630 share a similar altitude band with LEMUR 2 DEVERILL-M-T.
