LEMUR-2-NURAY

LEMUR-2-NURAY is an active satellite operated by Spire Global (Germany), launched on 2026-07-07 from Vandenberg SFB, California on the Transporter-17 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 583 km and 598 km with an inclination of 97.8°. It travels at approximately 27,241 km/h (7.57 km/s), completing one full orbit every 96 minutes — that’s roughly 14.92 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. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks LEMUR-2-NURAY in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

LEMUR-2-NURAY orbits at an average altitude of 591 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-NURAY’s average altitude, there are currently 2,084 active payloads and 608 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-3005, STARLINK-3090. This makes it one of the more crowded altitude bands, containing roughly 11.8% of all active satellites. With an inclination of 97.8°, LEMUR-2-NURAY passes over latitudes between 97.8°N and 97.8°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. Germany operates approximately 87 active satellites in total, of which 26 share a similar altitude band with LEMUR-2-NURAY.
