Vostok 1
From Memory Alpha, the free Star Trek reference
The Vostok 1 was an early Human spacecraft that carried the first Soviet cosmonaut into space in 1961, concluding with a single successful orbit of Earth.
An image depicting Vostok 1 was contained in the library computer aboard the USS Enterprise. This data was flashed on a viewscreen when the Talosians scanned the Enterprise computer in 2254. (TOS: "The Cage" remastered)
