Question by rani: The soviets launched sputnik 1 on October 4, 1957. Who were the key people and nations involved in this event?
This is for a homework assignment and i think i know the answer but im not sure. I think that the key nations would be the soviet union and the united states because the soviet union launched sputnik 1 and sputnik 1 also started the space race between the united states and the soviet union. I just dont know the key people and i need help on that. Thanks!!!!!!!!
