|  Overview STS-84 launched on May 15, 1997 with crew member Mike Foale. He replaced 
        Mir astronaut John Blaha and spent a total of 134 days in orbit. Foale 
        returned to Earth with STS-86, on October 6, 1997. Foale's mission proceeded 
        fairly normally until June 25, when during a test of a manual docking 
        system, a Progress resupply ship collided with Mir's Spektr module, causing 
        a depressurization of the space station. The crew closed the hatch to 
        Spektr, which stabilized the station's air pressure, while Spektr's pressure 
        dropped to a vacuum. The collision knocked Mir into a spin, at a rate 
        of about once every six minutes, but the crew members were able to stabilize 
        the station. Many of Foale's experiments and personal effects were isolated 
        within Spektr. Fortunately, food, water and other vital Mir supplies were 
        stored in other modules. In August, Foale's Mir-23 crewmates, Vasily Tsibliev 
        and Aleksandr Lazutkin, were replaced by Mir-24's Anatoly Solovyev and 
        Pavel Vinogradov, who arrived in a Soyuz vehicle. Later in the mission, 
        Foale and Solovyev conducted a 6-hour EVA to inspect the damage to the 
        punctured Spektr.
