Mars, 2059. Bowie Base One. Last recorded message: "Don't drink the water. Don't even touch it. Not one drop."

Doctor Who will return to Ö÷²¥´óÐã One on Sunday 15 November for The Waters Of Mars – the second of four specials airing throughout 2009.

Starring David Tennant as The Doctor and guest starring acclaimed British actress Lindsay Duncan – best known for her roles across stage and screen (Margaret, Rome) – The Waters Of Mars is set to be one of the most scary episodes of the series to date, as a creeping infection beneath the Martian surface threatens not only the human race, but also the Doctor's most fundamental beliefs – with terrifying results.

Lindsay Duncan stars as Adelaide – the Doctor's cleverest and most strong-minded companion yet.

Neighbours, Flying Doctors and Casualty star Peter O'Brien also guest stars as Ed, Adelaide's second-in-command at the base.

The Waters Of Mars is the second of four specials which will air throughout 2009.

The Waters Of Mars is written by Russell T Davies and Phil Ford and is directed by Graeme Harper. The producer is Nikki Wilson.
