Answer:
Soviet Union, Establishment of NASA.
Step-by-step explanation:
- The United States was in competition with the Soviet Union when it relates to “ruling the skies”.
- When Soviet Union launched Sputnik 1 in 1957, it intensified the race between the two countries as US feared of falling behind in the race of space exploration.
- As a result, the National Aeronautics and Space Act of 1958 was established and NACA incorporated itself with the newly established agency to win the competition.
