During the Cold War, the two superpowers (the United States and the Soviet Union) competed for dominance in spaceflight capability. Who accomplished these achievements first?
It's amazing how many firsts the Soviets established. I wonder if Moon and/or Mars bases would already be a thing of the past if they were still around.
18 is wrong, lunar soil samples were returned to earth with Apollo 11, over a year before Luna 16 brought samples back to Earth. The Soviets just built the first AUTOMATED soil sample return mission.
