Explorer

Explorer 1 was the United States' first satellite, launched on January 31, 1958. It was 203 cm long, 15.9 cm in diameter and weighed 14 kg. Its primary instrument was a cosmic ray detector to measure the space environment in low Earth orbit. Explorer 1 orbited Earth in a looping path every 1.6 hours at an altitude of 1,454 km, and its measurements confirmed the existence of the Van Allen radiation belts around Earth. It transmitted data until reentering the atmosphere and burning up on March 31, 1970 after completing over 58,000 orbits.
