Kosmos 434
Kosmos 434 ((ロシア語:Космос 434); meaning ''Cosmos 434'') was the final unmanned test flight of the Soviet LK Lander. It performed the longest burn of the four unmanned LK Lander tests. It finished in a 186 km by 11,804 km orbit. This test qualified the lander as flightworthy. The LK was the only element of the Soviet manned lunar programs that reached this status. In 1980-81 there were fears that it might carry nuclear fuel. When in reentered over Australia on August 22, 1981 the Soviet Foreign Ministry in Australia admitted that Kosmos 434 was an “experiment unit of a lunar cabin,” or lunar lander. ==See also==
