Eligius IV

Eligius IV is a mining ship and a space station previously owned by the Eligius Corporation. It was designed to be used for interstellar 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 300 prisoners, 25 guards and 12 crew members on board.

After a mutiny led by Charmaine Diyoza on 4 April 2047, 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 decades. Therefore the prisoners were put into cryosleep, and in 2156, Eligius IV finally returned to Earth.

Throughout the Series
6 years after Praimfaya, the Gagarin (A dropship from Eligius IV) landed on Earth, carrying Charmaine Diyoza and 22 other prisoners.

On the Ark, John 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 284 prisoners in cryo sleep. One of them, Kodiak, was woken up by Rankin to find out the reason the alarm was triggered and was killed by Bellamy and Echo. Later in order to have leverage over the prisoners already on the ground, Raven and Murphy stayed aboard to control the other prisoners still in cryo sleep. In the interval between Pandora's Box and Shifting Sands, the leaders of Eligius prisoners took the remaining people from the ship and brought them back to Earth, including Raven Reyes and John Murphy, thereby leaving the ship abandoned.

Location
Eligius IV is currently located in geosynchronous orbit right above the Eden
