The Mutara Interdimensional Deep Space Array System, or MIDAS array for short, was a Federation communications array that was in service with Starfleet in the late 24th century. Located near a small gas cloud, it utilized hyper-subspace technology to greatly reduce the time it would take for a message to reach its destination.

In 2376, Deep Space 9 predicted that a pulsar would pass close to the array. By firing a tachyon beam at the pulsar, Pathfinder Project was able to create a micro-wormhole through which they made contact with USS Voyager for a brief period.

Later, Pathfinder found a way to amplify the signal from the MIDAS array by bouncing it off a class B pulsar. This allowed a brief compressed data stream to be sent to Voyager about every thirty-two days, coinciding with the pulsar's rotation cycle. Initially Starfleet sent many letters, as well as tactical updates and stellar maps.

By 2378, Voyager was close enough to perform Operation Watson, which would allow eleven minutes of contact with the Alpha Quadrant through the array every day.
