STS-79 was the fourth in a series of NASA docking missions to the 
            Russian Mir Space Station, leading up to the construction and operation 
            of the International Space Station (ISS). As the first flight of the 
            Spacehab Double Module, STS-79 encompassed research, test and evaluation 
            of ISS, as well as logistics resupply for the Mir Space Station.
          STS-79 was also the first NASA-Mir American crew member exchange 
            mission, with John Blaha (NASA-Mir 3) replacing Shannon Lucid (NASA-Mir 
            2) aboard the Mir Space Station. The lettering of their names either 
            up or down denotes transport up to the Mir Station or return to Earth 
            on STS-79.
          The STS-79 patch is in the shape of the Space Shuttle's airlock hatch, 
            symbolizing the gateway to internationa cooperation in space. The 
            patch illustrates the historic cooperation between the United States 
            and Russia in space. With the flags of Russia and the United States 
            as a backdrop, the handshake of EVA-suited crew members symbolizes 
            mission teamwork, not only of the crew members but also the teamwork 
            between both countries' space personnel in science, engineering, medicine, 
            and logistics.
