Sputnik in the steppe

The steppe was the protagonist of one of the most important events in the history of space explorations. The very first artificial satellite was launched from Kazakhstan on October 4th, 1957. It was Sputnik 1, a metal ball provided with four antennas, a diameter of 58 cm and a weight of 83 kg. It orbited at an average height of approximately 600 km above the earth’s surface. It contained two radio transmitters powered by chemical batteries. It was followed by the whole world and listened to by the radar of many stations all over the world. The space rush had just began.
