TOMORROW-R2

TOMORROW-R2 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 237 km and 249 km with an inclination of 97.6°. It travels at approximately 27,947 km/h (7.76 km/s), completing one full orbit every 89 minutes — that’s roughly 16.12 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 TOMORROW-R2 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

TOMORROW-R2 orbits at an average altitude of 243 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 TOMORROW-R2’s average altitude, there are currently 126 active payloads and 3 tracked debris or rocket body fragments — notable neighbours include STARLINK-1143, STARLINK-1411, STARLINK-1606. With an inclination of 97.6°, TOMORROW-R2 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 12,360 active satellites in total, of which 109 share a similar altitude band with TOMORROW-R2.
