Project SCORE

From Free net encyclopedia

Template:Expert Project SCORE (Signal Communications Orbit Relay Equipment) was the world’s first communications satellite. Launched in an Atlas rocket on December 18 1958, SCORE provided a first test of a communications relay system in space and captured world attention by broadcasting a Christmas message via short wave frequency from President Eisenhower through an onboard tape recorder.

The SCORE satellite, an acronym for Signal Communication by Orbiting Relay Equipment was designed and built by Kenneth Masterman-Smith, a military communication research engineer, along with other personnel with the U.S. Army Signal Research and Development Laboratory (SRDL) at Fort Monmouth, New Jersey in a six-month effort.

The payload used store and forward technology, weighed 68 kg (150 pounds) and was built into the Atlas rocket. SCORE was placed into a 183 km by 1,481 km (114 mile by 920 mile) orbit, inclined 32.3 degrees, with a period of 101.5 minutes. Its batteries lasted 12 days and it reentered the atmosphere on 21 January 1959.Thirty years ago, on 18 December 1958, the world's first communications satellite was launched from Cape Canaveral, Florida.

The launching device for the communications package was an Air Force Atlas rocket. Both the rocket and its payload were placed in orbit.

SCORE was basically an experiment designed to test the feasibility of transmitting messages through the upper atmosphere from one ground station to one or more other ground stations. The result of the project was unquestionably a major scientific breakthrough which proved that active communications satellites could provide a means of transmitting messages of all sorts from one point to any other on the planet Earth.

The very first transmitted message from space to the world below: "This is the President of the United States speaking. Through the marvels of scientific advance, my voice is coming to you from a satellite traveling in outer space. My message is a simple one: Through this unique means I convey to you and all mankind, America's wish for peace on Earth and goodwill toward men everywhere."
