1970-072A
The standdown period for E-8-5 and for Proton came to an end in Sep 1970 following a successful suborbital launch the previous month, and the Soviet lunar program finally met with success. E-8-5 No. 406 left the pad on 1970 Sep 12 and returned a handful of lunar soil to Kazakhstan twelve days later.
