Laika is the first dog (female) to ever fly in space.
It is also the first living being that left the atmosphere of Earth and reached space, making 9 rotations around the earth, then dying.
She was born on August 10, 1954 on Earth and died on November 3, 1957 in space, being the first living thing to ever die outside of Earth.
On November 3, 1957, Laika was boarded the Sputnik 2, Sputnik 2 ship was hastily built by Russian engineers, because it was a launch deadline that had to be met. But they managed to finish it.
of the Soviet Union, after being chosen from a group of 3 dogs (Mușka, Albina and Laika) to be able to walk in space.
Laika was equipped with an oxygen cosmonaut's jacket, was properly equipped and was placed in a kind of container a little bigger than her and put on the ship.
The Sputnik 2 took off on November 3, 1957.
A few hours after take off , the ship detached from the components it did not need and began to rotate around the Earth.
After a few more hours, one of the compartments in the upper right of the ship showed "Failed" and it didn't work. In this time the Russians were constantly monitoring the ship. At first the puppy's heart rate increased, but then returned to normal, when the ship lost the upper right compartment.
The compartment began to burn and spread the fire throughout the ship. Laika died within minutes of the fire and several hours after launch, unable to go anywhere.
It was known in advance that it was a suicide mission, because the ship with which it took off could not return to Earth, meaning it was not designed for such a thing.
It was the first mission and it was not known exactly what was happening in the cosmos, so the Russians wanted to see what was happening to a living being.
Now, we owe Laika everything for the space travel we do these years.
Without her and without this experiment, we could not reach space now.
However, something strange happened 162 days after the rocket was launched and Laika's death. The remaining components of the Sputnik ship have returned to Earth! And he returned to Earth and the container in which Laika was. Unfortunately, everything was burned in that compartment, so Laika was indeed a space hero!
