NAVSTAR 85 (USA 581) is a payload in MEO orbit, operated by US Space Force Space Systems Command, launched 2026.
Orbital data last updated 3 days ago. This may not reflect the current orbital state, not for operational use or collision avoidance. That number is the age of the measurement itself, not of our last check. We look for newer orbital data every six hours and publish whatever the tracking catalogue has released; when nothing newer has been released, the measurement below stays where it is. This is normal for this orbit. 42 of the 187 tracked objects in MEO were also last measured at least this long ago. Objects on this kind of path spend much of their time far from the ground sensors that track them, so they are re-measured far less often than something in a low orbit passing overhead several times a day.
