Emergency EVA and hard dock. On April 11 Romanenko and Laveikin exited Mir to examine and, if possible, repair the problem with Kvant. They discovered a foreign object lodged in the docking unit, probably a trash bag they had left between Progress 28 and Mir’s drogue. On command from the TsUP, Kvant extended its probe unit, permitting the cosmonauts to pull the object free and discard it into space. Kvant then successfully completed docking at a command from the ground. The EVA lasted 3 hr, 40 min. The Kvant FSM undocked from Kvant on April 12, freeing the module’s aft port to fill in for the Mir aft port (figure 2-14).[1] |

Mir power shortage. The Soviets acknowledged that Mir was short on electricity. The situation became particularly difficult when melts lasting days were conducted using Korund 1-M. The Tamyrs spent most of May conducting medical experiments and Earth resources photography, activities which required little electricity.[2] |
