Polaris

Polaris, or 13th Station (formally known as Polaris Station), was a space station owned by Becca's company. It was used by Becca to conduct research on A.L.I.E. 2.0 for two years after the Nuclear Apocalypse. It was destroyed by Alpha Station on Unity Day in order to get the other stations to come into line and join the Ark.

History
Polaris Station is where Becca traveled to conduct her research on A.L.I.E. 2.0 after isolating A.L.I.E. in the mansion.

In 2054, Polaris was due to join the other twelve federation stations to form the Ark. However, upon discovering the nature of Becca's research on the station, Commander McAdams refused to begin docking maneuvers in fear of infecting the entire Ark mainframe with the second AI that Becca had made. Other stations threatened to stop docking maneuvers because Polaris has not started, and Alpha Station threatened them to comply with the docking or they would be blown out of the sky to send a clear message to the other space stations. Soon after, Polaris was destroyed by missile lunched from Alpha Station. Since then, Polaris was scrubbed from the Ark's history and considered a myth.

Moments before Polaris was blown up, Becca took the AI and launched down from the station in an escape-pod, becoming the sole survivor of Polaris' destruction. According to A.L.I.E. and Raven's trajectory calculations, debris from Polaris Station fell into the ocean.

Throughout the Series
The 13th Space Station is first mentioned by Finn in Unity Day, stating that it was destroyed in a conflict before the remaining stations decided to work together in order to obtain peace, something that wasn't talked about much on the Ark.

In Thirteen, Jaha is interested in finding out the truth about Polaris now that A.L.I.E. needs to find her second version and reveals what he knew as Chancellor, that the 13th Station, called "Polaris", was blown out of the sky. They hope to find the station Polaris, but A.L.I.E. and Raven's trajectory calculations show debris from Polaris Station fell into the ocean.

Notes and Trivia

 * Polaris links both Sky people and Grounder origin stories.
 * Becca was the sole survivor of Polaris' destruction. Becca took an escape pod just as the station was blown to bits. She traveled down to Earth, wearing an orange jumpsuit labeled "Commander", where she became the Commander and her Escape Pod inspired the name "Polis" for the Grounder capitol.
