The name "Sputnik" ("Спутник") comes from Russian where it means "satellite" or "fellow traveller".
Sputnik 1 was launched on October 4, 1957.See that page for mission details.
Sputnik 2 was launched some months later, and carried the first living passenger, a dog named Laika.The mission planners did not provide for the safe return of the spacecraft or its passenger, making Laika the first space casualty.
The first attempt to launch Sputnik 3 on February 3February 3 is the 34th day of the year in the Gregorian Calendar. There are 331 days remaining, (332 in leap years). In the Northern hemisphere, there are 88 days in winter (in a non-leap year).

Its tape recorderIn general, a tape recorder tape deck or tape machine is any device that records a fluctuating signal by moving a strip of magnetic tape across a tape head, which is a strong electromagnet. Current flowing in the coils of the electromagnet cause the magne failed, however, making it unable to measure the Van Allen radiation beltThe Van Allen radiation belt is a torus of energetic charged particles around Earth, trapped by Earth's magnetic field. When the belts "overload", particles strike the upper atmosphere and fluoresce, causing the polar aurora. The presence of a radiation bs.

Sputnik 5 was launched into orbit on August 19, 1960 with the dogs Belka and Strelka ( Russian for "Squirrel", or more likely "Whitey" from Russian "belyj", which means "white", and "Little Arrow"), 40 mice, 2 rats and a variety of plants on-board. The spacecraft returned to earth the next day and all animals were recovered safely.All Sputniks were carried to orbit by the R.7 launch vehicle, originally designed to carry ballistic warheads.
The surprise launch of Sputnik 1, coupled with the spectacular failure of the first two Project Vanguard launch attempts, shocked the United States, which responded with a number of early satellite launches including Explorer I, Project SCORE, Advanced Research Projects Agency and Courier 1B. Sputnik also led to the creation of NASA and major increases in U.S. Government spending on scientific research and education. See: Sputnik crisis.
