NAVSTAR 73 (USA 260) is a payload in MEO orbit, operated by US Air Force Space and Missile Center, launched 2015.
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. We could not compare this object with others in the same orbit just now, so we will not guess at a reason.Why?
