4. Historical Developments The first space mission, Sputnik 1 was an artificial satellite put into Earth orbit by the Soviet Union on 4 October 1957. On 3 November 1957, the Soviets orbited Sputnik 2, the first to carry a living animal into space – a dog. The United States achieved its first successful space probe launch with the orbit of Explorer 1 on 31 January 1958. Explorer 1 weighed less than 14 kilograms compared to 83.6 kg and 508.3 kg for Sputniks 1 and 2 respectively. Nonetheless, Explorer 1 detected a narrow band of radiation surrounding the Earth, named the Van Allen belts after the scientist whose equipment detected it.
