Starship Mission Status reports are a computer display available to Starfleet officers to brief them on the activities of other Federation starships and installations.
A readout of this nature for Sectors 21538 to 23079 was often displayed on a screen in the observation lounge of the starship Enterprise-D during the mid-to-late-2360s.
Background
The mission status readout was devised by Michael Okuda's art department, and featured the registry numbers, classes and assignments of many Federation starships mentioned during TNG's run. This display was never clear on screen, but has been reproduced in other media, and the info within has been adhered to by many later works including the Star Trek Encyclopediae.
