Eligius IV

Eligius IV is a mining ship previously owned by the Eligius Corporation. It was designed to be used for deep space missions to mine asteroids or to search for habitable planets.

On the side of the haul it states "Powering a Better Tomorrow", this most likely refers to the prisoners mining a renewable source of energy to power utilities.

History and Background
Sometime in the past, the Eligius Corporation sent out a mining mission into deep space with about 250 prisoners on board.

After a mutiny lead by Charmaine Diyoza, that killed the captain and the crew of the ship and destroyed one of the engines. The mutineers decided to return to earth, but with one less engine working, the journey home would take too long. Therefore the prisoners were put into cryosleep, and in 2156 Eligius IV finally returned to earth.

Season Five
6 years after Praimfaya, the Gagarin (A drop ship from Eligius IV) landed on earth, carrying Charmaine Diyoza and 22 other prisoners.

On the Ark, Murphy saw the station in the distance. Raven tried to radio the ship, but there was no response. As a quest to solve the group's fuel problems they flew to Eligius IV and found over 200 prisoners in cryo sleep. In order to have leverage over the prisoners already on the ground, Raven and Murphy stayed aboard to control the other prisoners still in cry sleep.
