Sanctuary Base 6

Sanctuary Base 6 was a base staffed with humans and Ood on Krop Tor. Sanctuary bases were well known to the Doctor, and were put together like "flat-pack furniture".

Sanctuary Base 6 was built by the Walker Expedition. The scientists involved were studying K37 Gem 5, a black hole and the power source keeping Krop Tor in perpetual motion around it. The base was destroyed when the planet was on was consumed by the black hole. (TV: The Impossible Planet / The Satan Pit)

It also had a system of service tunnels that ran underneath the base. These could be filled with air from the main control room, although this was challenging to maintain. Other notable features of the base included retractable glass roofs for external viewing, 10-mile lift shaft to Point Zero and a system of numbered doors which could be opened and closed by turning circular wheels. However, Rose noted that the base did not have a swimming pool or a Tesco. (TV: The Impossible Planet / The Satan Pit)

The Tenth Doctor kept his Sanctuary Base 6 space suit in the TARDIS. He wore it on the surface of Mars. The helmet was damaged in the escape from Bowie Base One and abandoned shortly after. (TV: The Waters of Mars) The Eleventh Doctor had replaced the helmet by the time he wore the suit on primordial Earth. (TV: Hide) The Twelfth Doctor later wore this same spacesuit along with similar ones being worn by Clara Oswald and Courtney Woods during their trip to the moon. (TV: Kill the Moon) Clara then wore this spacesuit on a trip with the Doctor and continued to wear it throughout their subsequent adventure with Vikings. The wiring on this spacesuit was later used to channel electricity from electric eels to immobilise the Mire suits. (TV: The Girl Who Died) Priyanka Maratha borrowed this suit from the Doctor and wore it to pilot the Haven. (COMIC: The Swords of Kali)
