Historical Record
The disappearance of the Event Horizon is the defining unsolved loss in the timeline. The ship leaves on its maiden voyage with a gravity drive designed by Dr. William Weir, intended to open a practical route toward Proxima Centauri. During the mission, the drive is authorized for use after the vessel reaches safe distance on ion thrusters. Up to that point, every stage fits the pattern of a controlled experimental test. The ship is new, the drive is the centerpiece of the mission, and the command structure treats the activation as the threshold to a new era in travel. Then the record breaks. Once the drive engages, the Event Horizon stops behaving like an ordinary spacecraft under observation.
What makes the disappearance historically important is the complete nature of the loss. Weir later explains that after activation there is no radar contact, no enhanced optical contact, and no radio contact of any kind. This is not a case of delayed telemetry, partial malfunction, or a ship limping off course. The Event Horizon is effectively removed from known space operations in a single event. From the standpoint of aerospace command, that transforms the vessel from an experimental success candidate into a classified mystery tied to the most ambitious propulsion technology ever fielded. The disappearance is therefore not just a missing ship incident. It is the collapse of certainty around the gravity drive itself.
The canon timeline anchors the disappearance to 2040. The main action of the film takes place in 2047, and the Event Horizon is consistently described as having gone missing seven years earlier. That gap is long enough for the loss to harden into legend inside the service. The ship is no longer simply overdue. It has become a historical absence, a mission everyone knows by name but nobody can explain. That status shapes the later response when the vessel appears again near Neptune. The reason the signal matters so much is that it comes from a craft long presumed lost beyond recovery, one tied to the single most controversial technological leap in human navigation.
Inside the broader chronology, the disappearance is the event that converts aspiration into warning. Before this moment, the gravity drive represents possibility, distance collapse, and interstellar reach. After this moment, it also represents uncertainty, fear, and the prospect that the ship has gone somewhere human planning did not understand. The disappearance matters because it interrupts a clear story of progress and replaces it with a void in the historical record. It leaves command without answers, leaves Weir bound to an unresolved project, and leaves the Event Horizon itself frozen in memory as the vessel that vanished at the exact moment it was supposed to make history.

FAQ
Q: When does the Event Horizon disappear?
The ship disappears in 2040 during its maiden voyage. The year is fixed by the later seven year gap before the 2047 recovery mission, but the exact day is not stated in canon.
Q: Why is the Event Horizon disappearance important?
It turns the first gravity drive mission into a major unresolved loss. It also creates the mystery that later forces command to investigate when the ship reappears near Neptune.
