1995-024A
77KSO (TsM-O, TKS 173), the Spektr earth resources module, was finally launched on 1995 May 20. Extra solar arrays were added late in the design process to alleviate Mir's severe power shortages. Launch mass of Spektr was 22000 kg, which was reduced to 19500 kg by the time it docked with Mir. Docking was delayed following problems with reconfiguring Mir to receive the spacecraft. It docked with Mir on the first attempt, unlike the earlier modules.
