port just vacated by Progress M-27. On May 28, in their fourth EVA of the mission, Dezhurov and Strekalov moved a docking cone (Konus), from the -Y port to the -Z port to serve as the docking receptacle for Kristall in its next move. The space-suited cosmonauts did this work from inside the depressurized base block transfer compartment. Second Kristall Move In another undocking and relocation sequence controlled rom inside the station, on May 30, Kristall was moved from the -X port to the -Z port. Because of a temporary failure in the hydraulic connections, the docking was not successful until the third attempt. June 1995 - Mir Expansion and Historic Docking Spektr Docking and Fifth EVA Despite anxieties about the automatic docking, the Spektr module successfully docked to the -X port under control of the Kurs system on June 1. The next day, in their fifth EVA, the cosmonauts again entered the depressurized base block to transfer compartment and moved the Konus from the -Z to the -Y port. With the Mir crew and TsUP ground controllers in joint control of the Spektr Layappa arm, the module was moved to the -Y port on June 2. After the redocking, the crew began checking out and activating the new module's systems and transferring new supplies of food, fueled and equipment from Spektr to other parts of the complex. On June 5, one of Spektr's four solar arrays failed to fully unfurl because a restraint that held it in place for launch failed to release, and the crew was unable to extend it by sending pulses of power to the motor or by firing Mir's thrusters. TsUP controllers, aided by videos transmitted to them by the crew, began plans for a sixth EVA so that the cosmonauts could release the stuck array. Thagard Surpasses Previous American Record Norm Thagard held a press conference on June 6, the day he surpassed the long-held record of U.S. human spaceflight duration of 84 days set by the Skylab 4 crew from November 16, 1973, to February 8, 1974. Kristall Relocated Again Before its last scheduled move of the Mir 18 mission, the cosmonauts had to install two new batteries in Kristall to boost its power supply enough to accomplish the undocking and redocking. Then on June 10, the module was undocked from the -Z port, and again with the use of Lyappa, moved to
