UnknownPayloadHEO
MOLNIYA 1-91 is a payload in HEO orbit, operated by Russian Military Space Forces, launched 1998.
Orbital data last updated 167 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 unusual even for this orbit: only 1 of the 43 tracked objects in HEO are this far behind. We do not know the reason. The tracking catalogue simply has not released a newer measurement for this object. This record was last refreshed on 2026-11-05.Why?
