Kosmos 434
Third and final uncrewed test flight of the Soviet lunar module
Kosmos 434, also known as T2K No.3, was the final uncrewed test flight of the Soviet LK Lander. It performed the longest burn of the four uncrewed LK Lander tests, validating the backup rocket engine of the LK's Blok E propulsion system. It finished in a 186 km by 11,804 km orbit. This test qualified the lander as flightworthy.
