On 18th December in 1958, World's first communication satellite, SCORE (Signal Communications by Orbital Relay Equipment), was launched. SCORE provided the second test of a communications relay system in space, the first broadcast of a human voice from space, and the first successful use of the Atlas as a launch vehicle. It captured world attention by broadcasting a Christmas message via shortwave radio from U.S. President Dwight D. Eisenhower through an on-board tape recorder.This satellite was to demonstrate the feasibility and explore problems associated with, operation of a satellite communication system. The performance was nominal with experiment operation for 12 days, planned orbit lifetime 20 days, actual orbit lifetime 34 days.
