This object will re-enter the atmosphere sometime around September 2037. Click here for a plot of this object's inclination and perigee distance over time, running from shortly after its launch in 1977 to re-entry. The pattern of oscillations in perigee eventually leading, decades later, to re-entry is a common one. The spacecraft launched by this booster did the same thing, re-entering in January 2019, as did 1964-054A = OGO-1 in August 2020.
