Oct 16, 1975: Launch
This was the second attempt by the Soviet Union to send an "advanced" lunar sample return craft to the Moon, equipped with the capability to dig for a deeper core. The first spacecraft (Luna 23) was damaged during landing on the Moon in October 1974.
On this mission, the first three stages of the Proton-K launch vehicle worked without fault, but the Blok D stage, during its first burn for insertion into Earth orbit, failed. The expensive payload burned up in Earth's atmosphere without ever reaching Earth orbit.
Launch Vehicle: 8K82K + Blok D (Proton-K no. 287-02)
Spacecraft Mass: About 5,800 kg
- stereo imaging system
- improved drill for sample collection
