OUTPOST MISSION 1

OUTPOST MISSION 1 is an active satellite operated by United States, launched on 2023-06-12 from Vandenberg SFB, California. It orbits in Low Earth Orbit (LEO) at altitudes between 250 km and 262 km with an inclination of 97.6°. It travels at approximately 27,920 km/h (7.76 km/s), completing one full orbit every 90 minutes — that’s roughly 16.09 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 weeks to months. Orbital Radar tracks OUTPOST MISSION 1 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

OUTPOST MISSION 1 orbits at an average altitude of 256 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 OUTPOST MISSION 1’s average altitude, there are currently 140 active payloads and 3 tracked debris or rocket body fragments — notable neighbours include STARLINK-1151, STARLINK-1143, STARLINK-1320. With an inclination of 97.6°, OUTPOST MISSION 1 passes over latitudes between 97.6°N and 97.6°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 12,339 active satellites in total, of which 121 share a similar altitude band with OUTPOST MISSION 1.
