when did sputnik 2 come back to earth
Sputnik 2 Sputnik 2 reentered the Earth's atmosphere 14 April 1958, at approximately 0200 hrs, on a line that stretched from New York to the Amazon. Its track was plotted by British ships and 3 “Moon Watch Observations”, from New York. It was said to be glowing and did not develop a tail until it was at latitudes south of 20 degrees North. Estimates put the average length of the tail at about 50 nautical miles. The satellite burned up in the atmosphere.[22]

Laika, a stray dog from the streets of Moscow, was selected to be the occupant of the Soviet spacecraft Sputnik 2 that was launched into outer space on November 3, 1957.
