Mission control centers process, analyze, and distribute spacecraft [[telemetry]], and issue [[telecommand|command]]s, data [[upload]]s, and [[Software maintenance|software updates]] to spacecraft. For mannedcrewed spacecraft, mission control manages voice and video communications with the crew. Control centers may also be responsible for [[configuration management]] and data [[backup|archival]].{{r|Fortescue-GS}}{{rp|483}} As with ground stations, there are typically backup control facilities available to support continuity of operations.

====Staffing====

Control centers may be [[shift work|continuously]] or [[Business hours|regularly]] staffed by [[flight controller]]s. Staffing is typically greatest during the [[Launch and Early Orbit phase|early phases]] of a mission,<ref name=ley/>{{rp|21}} and during [[mission-critical|critical]] procedures and periods.<ref name=aiaa/> Increasingly commonly, control centers for unmanneduncrewed spacecraft may be set up for "lights-out" (or [[automation|automated]]) operation, as a means of controlling costs.<ref name=aiaa/> Flight [[remote monitoring and control|control]] software will typically generate [[notification system|notifications]] of significant events – both planned and unplanned – in the ground or space segment that may require operator intervention.<ref name=aiaa/>
