Stalin did not decide to proceed with Soviet production of this copy of the German V-2 until 1948. Despite the threatening supervision of the program by Stalin's secret police chief, Beria, and the assistance of German rocket engineers, it took eight years for the German technology to be absorbed and the missile to be put into service. It was almost immediately superseded by later designs, but the effort laid the groundwork for the Soviet rocket industry. Surplus R-1's were converted to use as a sounding rockets for military and scientific research missions.]]> 2021-09-09 00:21:03 UTC https://padlet.com/tabayawickrama/en05hd07rnhnoatl/wish/1726335333 tabayawickrama https://padlet.com/tabayawickrama/en05hd07rnhnoatl/wish/1726336559 Explorer 6, or S-2, was an American satellite launched on August 7, 1959.
