Definition

The instant when a spacecraft applies the departure impulse from a parking orbit (e.g., LEO). Departure time is a key parameter affecting the existence of transfer solutions and insertion cost, often fixed or used as a continuation parameter in pseudo-arc continuation.

Application Value

Departure Time plays an important role in orbit maneuver design, analysis, and transfer planning for cislunar missions.
