Question

Short on sputnik satellite

Answer 1

Sputnik 1 was the first artificial Earth satellite. The Soviet Union launched it into an elliptical low Earth orbit on 4 October 1957, orbiting for three weeks before its batteries died, then silently for two more months before falling back into the atmosphere.

The control system of the Sputnik rocket was adjusted to an intended orbit of 223 by 1,450 km (139 by 901 mi), with an orbital period of 101.5 min. The trajectory had been calculated earlier by Georgi Grechko, using the USSR Academy of Sciences' mainframe computer.

Im 2018 NASA says that sputnik satellite was 200 million km away from Earth and NASA wants to wait 30 hour's to receive its one signal....
