Jade Pagoda

The Jade Pagoda was a TARDIS 'escape pod', it was first used by the Seventh Doctor to travel to Earth in 2006 while the TARDIS had broken up between Earth 1909 and Antýkhon 22,000. (NA: Iceberg, Birthright)

In the second instance of its usage, it was used in the TARDIS that the Doctor obtained from a parallel Earth. (NA: Blood Heat)

In this second usage it was utilised by the Doctor and Bernice Summerfield to escape the TARDIS as it passed a black star. (NA: Sanctuary)

Specifics
The Jade Pagoda looked like it was made of marbled jade. It homed in on a main sequence G-type star with a class M planet in orbit. Most of the controls were for life support and homing the TARDIS to its location.

There was a tall mirror within that would become a scanner, there were also various first-aid and survival tools within the Jade Pagoda. Like TARDISes it was dimensionally transcendental, but only had the single console room with a series of cupboards containing the various supplies. (NA: Sanctuary)
