The mission provided scientists with the first data on the behavior of a living organism in the space environment.
Although the time between Sputniks 1 and 2 was only 32 days, the plan to launch a dog was planned more than a year in advance.
What was Sputnik 2 mission?
Sputnik 2 was launched on a Sapwood SS-6 8K71PS launch vehicle (essentially a modified R-7 ICBM similar to that used for Sputnik 1) to a 212 x 1660 km orbit with a period of 103.7 minutes. The orbit of Sputnik 2 decayed and it reentered Earth’s atmosphere on 14 April 1958 after 162 days in orbit.
What was the purpose of Sputnik?
Sputnik’s official designation was “PS-1” or “Elementary Satellite 1” in Russian. The satellite was launched from what is now called the Baikonur Cosmodrome on Oct. 4, 1957. The 184.3-pound (83.6 kg) craft’s primary function was to place a radio transmitter into orbit around the Earth.
Who built Sputnik 2?
Why did Laika the dog die?
In 1999, several Russian sources reported that Laika had died when the cabin overheated on the fourth orbit. In October 2002, Dimitri Malashenkov, one of the scientists behind the Sputnik 2 mission, revealed that Laika had died by the fourth circuit of flight from overheating.
Is Sputnik 2 still in orbit?
Sputnik 2 reentered the atmosphere on April 14, 1958 after 162 days in space and about 2500 orbits. After Sputnik 2 reached orbit, the interior temperature rapidly climbed to over 40 °C (100 °F), and Laika survived for only a few hours instead of the planned ten days.
Is Sputnik 1 still in orbit?
The Vanguard 1 satellite is still up there and is the oldest human-made object in space. It’s our first piece of space archaeology. Other early satellites – such as Sputnik 1, the first satellite to leave Earth in 1957, and Explorer 1, the first US satellite – have long since re-entered the atmosphere and burnt up.
