The STS-74 crew patch depicts the orbiter Atlantis docked to the Russian Space Station Mir. The central focus is on the Russian-built docking module, drawn with shading to accentuate its pivotal importance to both STS-74 and the NASA-Mir Program. The rainbow across the horizon represents the Earth's atmosphere, the thin membrane protecting all nations, while the three flags across the bottom show those nations participating in STS-74: Russia, Canada, and the United States. The sunrise is symbolic of the dawn of a new era in NASA space flight , that of International Space Station construction.
