Marina Verenikina, a.k.a. Marina V, wrote the lyrics to the theme song, Gagarin March with Chorus. The March was supposed to sound like an authentic 1960s piece straight out of the USSR. "I grew up in Moscow in the very end of the Soviet regime, and I remember singing the Soviet anthem and other Soviet songs as a kid. It really helped me in writing the lyrics for the song. When my mom heard it, she said she was amazed how real it felt", Marina adds.
Narrator Elliott Gould starred in the film Capricorn One (1977), in which NASA fakes a Mars landing.
