TECHNICAL DEFINITION

A Mission Timeline is a chronological sequence of planned events, commands, and maneuvers for a spacecraft or mission, specifying the precise timing and duration of critical activities, payload operations, and system reconfigurations.

BACKGROUND

Missions to the Moon have been numerous and represent some of the earliest endeavours in space missions, with continuous exploration of the Moon beginning in 1959.
