Ancient warship in service during the First Siege of Atlantis. The Aurora was dispatched to the outer rim of the Pegasus Galaxy in the hopes of gathering information pertaining to a weakness in Wraith defenses.
Eventually the Aurora succeeded in its mission, but it was unfortunately ten thousand years late. The ship only began a course back to Atlantis when it reactivated itself following the initiation of a homing beacon in the Lantean System.
The Aurora contained hundreds of stasis pods for the crew to inhabit during extremely extended journeys or in the event that life support failed. Within the pods was a vast network where each user could connect themselves to an artificial reality. This reality was directly linked to the ship's actual computer database. From the virtual environment changes could be made, and files even deleted, from within the artificial world.
The Aurora was destroyed when Colonel John Sheppard was given self destruct codes by the Captain himself, after he realized that he and his crew were too old and beyond help. With the destruction of the ship, two Wraith cruisers were prevented from reporting Atlantis's survival to the rest of the hive who believed it had been destroyed.
Aurora - After locating the Aurora on long-range sensors the Daedalus is sent to intercept the ship and determine what has become of her after ten thousand years.
