injury healed and the EVA plans proceeded. First Mir 18 EVA On May 12, Dezhurov and Strekalov began their first EVA to prepare the station for Spektr's arrival, exiting the Kvant 2 airlock at 4:20 UTC and transferring to the Kvant astrophysics module by means of the STrela boom. There they installed electrical cable attachments and adjusted solar array actuators. Then they moved to Kristall and practiced folding three panels of the solar array to be moved to Kvant. Thagard supported the crew from inside Mir by relaying instructions from the ground or from reference manuals when the station was not in range of ground communications. The spacewalk lasted 6 hours and 15 minutes. Problems on the Second EVA In their second space walk, on May 17, the cosmonauts successfully folded the solar array panels, assisted by Thagard, who controlled servomotor switches from inside Kristall. The spacewalkers disconnected the array from Kristall, attached it to the Strela boom, and moved it to Kvant. The work took so much time that, having already almost used the oxygen available through their suits, they were forced to secure the array to Kvant with tool teathers and postpone electrical connection. Even so, the EVA lasted 6 hours and 52 minutes. Power supply inside the station suffered without the connection of the array, necessitating interim agumentation by Progress M-27 and Soyuz TM-21's solar arrays. Solar Array Redeployed in Mir 18 Third EVA On their May 22 walk of 5 hours and 15 minutes, Dezhurov and Strekalov successfully connected the solar array to Kvant, and Thagard commanded its redeployment from inside the station. The cosmonauts then returned to Kristall, where the retracted 13 panels of another solar array to provide clearance for rotation of Kristall during its relocation to make room for Spektr. Approximately 60% of that array was still available as a power source. Progress M-27 Undocks to Free -X Port Progress M-27 left Mir at 23:53 UTC on May 22 and made a destructive reentry into the Pacific on May 23. Thus the -Y port was freed for use in the multiple module relocation that would be necessary for the docking and ultimate permanent placement of Spektr. First Kristall Move and Fourth EVA From inside the station, Dezhurov controlled the undocking of Kristall on May 26 from the -Y port. Then the module was moved by means of its Lyappa arm to the -X
