Empress of Mars" is the ninth episode of the tenth series of the British science fiction television series Doctor Who. It is written by Mark Gatiss and was broadcast on 10 June 2017 on BBC One. "Empress of Mars" received generally favorable reviews from television critics.

The Doctor (Peter Capaldi), Nardole (Matt Lucas), and Bill (Pearl Mackie) travel to Mars, but upon arrival, they find themselves in the middle of a conflict between the Ice Warriors and Victorian soldiers. The episode marks the return of the Ice Warriors, last seen in "Cold War", an episode of the seventh series that was also written by Gatiss.




On Earth 2017, NASA finds the words "God save the Queen" made of rocks buried under the ice cap of MarsThe DoctorBill and Nardole venture to Mars in 1881 to investigate, and they discover that the planet is occupied by human soldiers from Victorian Britain. Nardole goes back into the TARDIS, but it departs for unexplained reasons, returning to the university in present day. Nardole has to ask Missy for help getting back.

The humans have befriended an Ice Warrior they have named Friday. Captain Catchlove says they rescued Friday from his crashed spaceship while on patrol in Africa. In exchange, Friday allowed the soldiers to use his species' technology to travel to and mine Mars. The Doctor surmises that Friday is using them to access to his hive. They soon unearth the tomb of the Ice Queen. Despite Colonel Godsacre's order to not approach it, one guard cuts a crystal from the base of the tomb which revives the Ice Queen, Iraxxa.

Iraxxa's waking leads to a confrontation with the humans. Friday tells Iraxxa it has been 5,000 years, and Mars' surface is uninhabitable; the Doctor asks Iraxxa to show mercy and gain help from the humans. Dismissing the Doctor and the soldiers, she asks Bill for her opinion, as a fellow woman. She decides to relent based on Bill's word, but then a soldier suddenly fires his rifle, the shot harmlessly glancing off Iraxxa's helmet. Provoked, she returns fire. Catchlove takes command, locking up the Doctor, Bill, and Godsacre, and traps Iraxxa and Friday within the tomb, where they start reviving more Ice Warriors.

As the Ice Warriors launch their attack, Friday allies himself with the Doctor and Bill and helps the Doctor gain control of the mining device. The Doctor threatens to use it to bury all under the ice cap. Catchlove holds Iraxxa at knifepoint and attempts to force her to help him pilot a spaceship back to Earth. Godsacre manages to surprise Catchlove and kills him, then begs Iraxxa to kill him. Iraxxa calls off the attack in exchange for Godsacre pledging himself to the Ice Warriors. The Doctor covertly contacts Alpha Centauri to assist the Ice Warriors.

The Doctor and Bill help Godsacre leave the message that NASA will discover. Nardole re-appears with the TARDIS. Missy is also on board and expresses concern about the Doctor's health.
