The wait is nearing it's end, as we are now only hours away from the broadcast of The Waters of Mars. The long anticipated episode is the second of the Doctor Who 2009 specials and stars David Tennant as The Doctor, and Lindsay Duncan as Adelaide, the captain of Bowie Base One and The Doctor's companion for this adventure. The story sees The Doctor visit the Human pioneers of Mars on a fixed day in history where what happens can not be changed. With The Flood infecting the crew of the Mars base, and Adelaide facing certain death, it seems that there is more to the red planet then meets the eye. The episode runs for approximately one hour and will be broadcast at 7.00pm on BBC One and on the BBC HD channel, with it's accompanying episode of Doctor Who Confidential being transmitted at 8.00pm on BBC Three. The special Doctor Who episode will be followed by a trailer for the next special, which is expected to reveal the title of the episode, and that will be posted here, on The Gallifrey Vortex, after. I hope that you fully enjoy tonight's broadcast of Doctor Who: The Waters of Mars.
