Mir base block, Kvant, Kvant 2, and Kristall (1994) klipart

Note the Sofora boom and VDU and the Rapana girder attached to the top of Kvant, the Strela boom attached to the side of the base block, and the support on the side of the Kvant module. A matching support is attached to Kvant’s other side, out of view. Eventually Kristall’s two solar arrays will be relocated to these supports. Soyuz-TM and Progress spacecraft are omitted for clarity.
