reboost

/ˌriːˈbuːst/

Definition

The act of increasing the altitude or velocity of a spacecraft or satellite that has begun to drift from its intended orbital path due to atmospheric drag or other factors.

Etymology

The word is a combination of the Latin-derived prefix 're-', meaning 'again,' and the English verb 'boost,' which likely originated from 18th-century slang meaning to lift or push from below. In an aerospace context, it was adopted in the mid-20th century to describe the specific maneuver of pushing a craft back to a higher trajectory.
