L1S n°1 & LK n°1

The Zond L1S n°1 spacecraft was going to perform a flyby of the Moon.

The LK Model was a mass representative of the Soviet LK crewed lunar lander. The LK spacecraft can be subdivided into the lunar landing aggregate ("Lunnyi Posadochnyi Agregat", "LPA") and the lunar ascent vehicle, ("Lunnyi Vzletnyi Apparat", "LVA'"). Propulsion, both for landing and lifting off the Moon was based on the Blok E propulsion system. The Information Display System (spacecraft control panels and controls) version was called Luch.
