Atlas-Agena
From Memory Alpha, the free Star Trek reference
The Atlas-Agena was a 20th century expendable rocket used by NASA for launching payloads into space.
A black-and-white drawing of the launch sequence for the Atlas-Agena was stored in the USS Enterprise library computer. This drawing was later retrieved by the Talosians when they accessed the starship's computers in 2254. (TOS: "The Cage")
