Kristall Module

Image of Kristall Module

Berthed opposite Kvant 2 in 1990, Kristall weighs 19.6 tons and carries two stowable solar arrays, science and technology equipment, and a docking port equipped with a special androgynous docking mechanism designed to receive heavy (up to about 100 tons) spacecraft equipped with the same kind of docking unit. The androgynous unit was originally developed for the Russian Buran Shuttle program. Atlantis used the androgynous docking unit on Kristall during mission STS-71.

Added in 1990, Kristall carries scientific equipment, retractable solar arrays, and a docking node equipped with a special androgynous docking mechanism designed to receive spacecraft weighing up to 100 tons.

The purpose of the Kristall module is to develop biological and materials production technologies in the space environment. One component of the Kristall is a radial docking port. Originally designed as a potential means of docking the Russian Buran reusable shuttle orbiter, this port is now attached to the Docking Module.
