Atlantis away. As Atlantis slowly flew around the station, Soyuz TM-21 redocked and the two craft continued to take pictures of each other and Mir. Gibson called this set of celestial maneuvers a "cosmic ballet." However, after the Soyuz module had to redock a few minutes sooner than planned when the Mir onboard computer which controls station attitude and solar array pointing malfunctioned. The station complex, about 10 degrees of the correct attitude, was becoming unstable and starting to drift. The cosmonauts had to get back quickly to regain attitude control of the station. TsUP controllers left the station in free drift while the cosmonauts replaced attitude-control hardware in the computer. First EVA of Mir 19 Before their launch, Solovyev and Budarin had trained to use the new tools created for releasing the stuck Spektr solar array. On July 14, they exited the Kvant 2 hatch and made their way to Spektr using the Strela boom. They quickly cut the offending restraint, and all but one section of Spektr's jammed solar array deployed. Then they were able to route the power input to the complex. They inspected the -Z port docking mechanism and found no signs of damage or pollution, clearing the port for relocation of the Kristall module. Before reentering the Kvant 2 hatch, they inspected one of that module's solar arrays which was not tracking the sun correctly. Their EVA ran five hours and 34 minutes, about twenty minutes over the originally budgeted time. Kristall Relocated Once More In a 90-minute session on July 17, Kristall was transferred by means of its Lyapa arm to the -Z docking port from the -X port where Progress M-28 docked later in July. Problems During the Second Mir 19 EVA The primary purpose of the second space walk on July 19 was to deploy the Belgian-French MIRAS (Mir infrared spectrometer) on the far end of the Spektr module. But minutes after the EA began, Solovyev's Orlan-DMA suit cooling system malfunctioned and the TsUP ordered him to stay attached by an umbilical to Kvant 2. The MIRAS deployment had to be postponed, but Budarin was able to do some preparatory work alone. he also retrieved the American cosmic ray detector, TREK, which had been on Kvant 2 surface since 1991 and switched out cassettes of sample construction materials as part of an ongoing space exposure experiment. his time outside totaled 3 hours
