Labels:text | screenshot | font | number OCR: FACT FILE KVANT, THE FIRST addition to the main Mir module, docked directly onto Mir's rear port; the other modules each docked with the multiple docking adapter. To prevent destabilizing the space station, each first docked in-line with the main module, on the end port of the adapter. A manipulator arm then gently moved the module to its permanent position on a side port of the adapter, leaving the end port free for Soyuz craft.
