16th expedition to Mir.

First Soyuz without a probe and drogue docking system since 1976.
It carried
an APAS-89 androgynous docking unit different from the APAS-75 unit used for ASTP in 1975, yet similar in general principles.
Soyuz-TM 16 used it to dock with an androgynous docking port on the Kristall module.
This was a test of the docking system in preparation for dockings by the Space Shuttles with Mir.
