Laika is one of the names that are known to the female dog that November 3 1957 left Earth aboard the space capsule Soviet Sputnik 2 .
Kudrjavka His real name was, and is often called Muttnik (from which in English means mutt mutt Sputnik and the name of the dish). The capsule
Sputnik 2 was equipped for life support and carried food and water but did not plan to return, then the fate of Laika was marked from the beginning of the mission. The capsule was also equipped with sensors that permit monitoring of the passenger's vital signs as blood pressure , heartbeat and breathing rate . Until recently it was certain that after the launch of Sputnik 2 from the Baikonur Cosmodrome , Laika had come alive in orbit but after the entry into the orbit of the details his fate was uncertain. There are in fact different versions of the facts mixed.
According to some sources, Laika died a few hours after the entry into orbit, while others estimate that Laika survived for about ten days (hypothesis unlikely because the batteries that powered the systems of Sputnik 2 ran out after about six days).
The official version of the time given by the Soviet government is that Laika survived for "over four days." However, in October 2002 were made public the results of new research by a Russian scientist ( Dimitri Malashenkov ), which revealed that Laika survived for only a period of between 5 and 7 hours after takeoff because of hot and cold temperature changes.
