The display in Leicester opened on November 13 and will be there until January 6, 2008.
According to promotional material, it includes Martha's and the Master's costumes, as well as Weeping Angels, Witches (presumably Carrionites), Daleks and Cybermen plus other foes, although the official exhibitions site says there will be just one each of the Angels, Witches and Cybermen, plus a Dalek Encounter.
The centre also hopes to have exhibits from the Christmas special, Voyage of the Damned, in January.
Entry is free for all ticket-holders to the National Space Centre. However, school bookings do not include entry to the exhibition. The centre is open Tuesdays to Sundays. During school holidays, it is also open on Mondays.
The centre, in Exploration Drive, previously hosted an Up Close exhibition from November 22, 2005 to January 8, 2006.
