Detailed explanation-1: -On August 12, 1960, NASA sent a 100-foot balloon into Earth orbit. Made of a relatively new plastic material called Mylar with a thin aluminum coating, the Echo 1 balloon became the world’s first passive communications satellite.
Detailed explanation-2: -Launched in 1960, Echo 1 was designed to explore the new field of communications via space. Its design was remarkably simple: Essentially a large balloon, measuring 30 meters (100 feet) across, the satellite provided a reflective surface in space.
Detailed explanation-3: -Echo 1 was 30 m (98 ft) in diameter, had a non-rigid skin made of 12.7 m (0.00050 in)-thick Mylar, and had a total mass of 180 kg (400 lb), weighing 71 kg (157 lb) at launch.
Detailed explanation-4: -On October 4, 1957, the Soviet Union launched the earth’s first artificial satellite, Sputnik I. The successful launch came as a shock to experts and citizens in the United States, who had hoped that the United States would accomplish this scientific advancement first.
