Specifics
The Jade Pagoda looks like it is made of marbled jade. It homes in on a main sequence G-type star with a class M planet in orbit. Most of the controls are for life support and homing the TARDIS to their location. There is a tall mirror inside which becomes a scanner, there are also various first aid and survival tools within the Jade Pagoda. Like the TARDIS it is dimensionally trancendental, but only has the single console room with a series of cupboards containing the various supplies. (NA: Sanctuary)
