< Atlantis
- "An ascension machine?"
- ―John Sheppard[src]
The Ascension lab is located in one of the previously flooded areas of Atlantis. The Ancients used it to develop a means to rapidly evolve in order to ascend. A device in the center of the room, when triggered, causes the user to evolve at an accelerated rate, eventually reaching a point where they can ascend if they have the discipline; otherwise, it results in death.
The room was discovered while searching the area for a device the Ancients turned back on when they were once again in control of Atlantis. (SGA: "The Return, Part 1")
Dr. Rodney McKay entered the room and stepped up to the console and inadvertently activated the device. (SGA: "Tao of Rodney")
