Ceremonial flag of Soyuz MS-18 ISS Expedition 64.

The size of the flag is 39” x 59 “, double faced.

Soyuz MS-18 crew emblem prominently displays the spacecraft on a shield-shaped background. The spacecraft designation, the crew members names and the Roscosmos logo fill the top of the patch design. Blue and purple rays make up most of the background, symbolizing the depths of the cosmos and the far reaches cosmonautics sets its sights on, both in science and in future destinations. Three yellow stars represent the three members of the crew. Soyuz's orbital target, the International Space Station is depicted as a silver silhouette. The lower end of the design is occupied by the Kazabek mountain, representing the call-sign of this mission. The patch border displays the flag of Belarus at the top for commander Oleg Novitskiy's nation of birth, the flag of the Russian Khabarovsk territory on the left representing cosmonaut Pyotr Dubrov's origins and on the right, are the USA's national colours for astronaut Mark Vande Hei. The Russian flag is positioned on the spacecraft itself. A banner across the bottom of the design shows the years 1961 and 2021 and the number 60 in between, commemorating Yuri Gagarin's trailblazing first human spaceflight, six decades ago this year.
