During this incident, The Doctor undergoes a partial regeneration in order to repair damage from a Dalek blast; as a result of this, the Doctor's severed hand later forms a mental link with Donna and grows into a second version of the Doctor, but one that's half-human without Time Lord biological abilities such as regeneration. During ths incident, [Martha Jones]], under orders from UNIT, reveals the existence of the Osterhagen Key, a weapon capable of destroying Earth.

 * 02 - Who fandom is caught by surprise when the BBC announces that the actor to play the Eleventh Doctor is to be announced in a special edition of Doctor Who Confidential the next day,
 * 03 - During a special edition of Doctor Who Confidential, the BBC announces that Matt Smith has been cast as the Eleventh Doctor.

 * 06 - John Scott Martin dies.
 * 14 - Production begins on Planet of the Dead with the first cast read-through of the script. David Tennant, as he did regularly during Series 2 and 3 and less regularly during Series 4, records the event for posterity for a series of video diaries (dubbed "The Tennant Tapes") later posted to the BBC's website.

 * 19 - Filming begins on Planet of the Dead, the first of four one-hour Doctor Who specials to air during 2009 and early 2010 in lieu of a full season. These specials will mark the end of David Tennant's era as the Tenth Doctor, and also conclude Russell T Davies and Julie Gardner's tenures as producers. Concurrent with the start of production are rumours that Michelle Ryan and Lee Evans had been cast in the special. The rumours are later confirmed by the BBC, which releases publicity photographs of Ryan with David Tennant. According to Doctor Who Magazine #405, Planet of the Dead is the first Doctor Who episode to be produced in high-definition.

The resulting BBC News report serves as confirmation to earlier rumours that Doctor Who is in fact filming at least part of Planet of the Dead in the Middle Eastern country. This marks the first full-scale production of a Doctor Who installment outside Europe since the 1996 telefilm was shot in Canada and only the second regular TV episode to film major scenes outside Europe since Planet of Fire was partially filmed in the Canary Islands in 1984.

This ends speculation over the future of Doctor Who on the CBC, although it's not yet known whether the CBC or related networks will retain broadcast rights to the first four seasons. Up to at least the end of Series 4, the CBC had been a (sometimes-credited) co-producer of the series; presumably this announcement means that arrangement has ended.
 * 11 - Broadcast of Planet of the Dead, the first of four one-hour special episodes of Doctor Who scheduled for broadcast during 2009 and early 2010 in lieu of a regular season in 2009. Co-written by Russell T. Davies and Gareth Roberts, it is the first episode on which Davies shares writing credit, is the first episode of the revived series to credit two writers, and is the first story to credit two writers since 1993's Dimensions in Time. It is also the first episode (as opposed to telemovie) of the series to be filmed in part outside Europe since 1984. The BBC did not officially announce the broadcast date until 1 April, leading to some erroneous reports that it would air on Easter Sunday itself, 12 April. The special, the first to be filmed in high-definition, was simulcast on BBC HD. An instalment of Doctor Who Confidential followed on BBC Three.
 * 16 - Publication of Judgement of the Judoon, Prisoner of the Daleks and The Slitheen Excursion.

Summer

 * Series 3 of Torchwood is expected to air in the summer of 2009, "possibly late June or early July" according to BBC America president Gareth Ancier speaking after a Television Critics Association meeting in January (contradicting a report in Doctor Who Magazine #400 that said Spring 2009). According to Ancier, the plan as of January 2009 is for both BBC One and BBC America to air the series on the same day, the first time in franchise history such an international broadcast has coincided in this way. The third season will consist of a single five-episode story arc entitled Children of Earth. The cable network Watch has suggested the BBC may air the storyline the week of 15 to 19 June, but this has not yet been confirmed.

July

 * Big Finish marks the 10th anniversary of its line of Doctor Who audio productions.
 * IDW Publishing is scheduled to launch Doctor Who Ongoing, a new comic series featuring the adventures of the Tenth Doctor.

As of January 2009 it's not known yet whether these will be the final Tenth Doctor novels.
 * Scheduled publication of The Dalek Project, the first graphic novel to be published by BBC Books.

Late 2009

 * According to Russell T. Davies in SFX Magazine, the second of the 2009 Specials, The Waters of Mars, is scheduled to air around Christmas 2009 (though whether this means December 25 has yet to be confirmed as of March 2009), followed possibly by one or both of the remaining specials leading to David Tennant's regeneration into Matt Smith. In early April 2009, however, Davies indicated that a "November-ish" broadcast was being considered for The Waters of Mars. As of May 2009 the only official word from the BBC, coming from the trailer featured at the end of Planet of the Dead is "later this year".

December

 * 06 - 20th anniversary of the broadcast of Survival Episode 3, the final episode of the original 1963-1989 series.

Unannounced dates

 * Production of the 2010 series is expected to begin, with Steven Moffat as new head writer and Piers Wenger as new producer and Matt Smith in the role of the Eleventh Doctor. Doctor Who Magazine, in an article on Smith published in early 2009, hinted that production could begin in mid-year.
 * The first season of the Australian-made spinoff series K-9 is expected to air in that country sometime in the second half of 2009, likely carrying over into 2010. Broadcast of the series in other countries has yet to be confirmed.
