What maneuver must an upper stage typically perform when placing a payload into Geostationary Orbit (GEO)?
Answer
A final 'disposal burn' into a graveyard orbit.
For missions going to higher, stable orbits like GEO, the upper stage is intentionally commanded to execute a final disposal burn. This maneuver increases its altitude significantly, placing it into a graveyard orbit where it remains safely separated from active assets for centuries.
