Joint Chiefs Chairman Gen. Joseph Dunford described the re-establishment of the new U.S. Space Command as a "Sputnik moment" in a ceremony at Peterson Air Force Base in Colorado Springs, Colo.

Dunford compared President Donald Trump's re-start of the U.S. Space Command to President John Kennedy's call to action after the Soviet Union started the space race with Sputnik, the first space satellite, and 1961's first manned launch into space.
