Between the '60s and '70s, there was great competition between the US and the Soviet Union to keep themselves ahead in the Space Race. This was the period when many discoveries were being made in the field of space research. In this context, November 3, 1957 is a very important day in the history of space because on this day the Soviet Union sent a dog named Laika to a spacecraft named Sputnik-2. Not only this, Laika sat in the Sputnik 2 vehicle and made rounds of space in the orbit of the Earth. Under this mission, the Soviet Union was trying to know if a human being could be sent into space, how safe would be, and what would be the effect on him. However, unfortunately, Laika could not return to Earth alive.
It was a suicide mission because this was the period when humans had learned to send spacecraft into space. However, how to bring him back to Earth? Nobody knew anything about this.
The spacecraft in which Laika was sent. There were many technical flaws in it. This rocket was not able to return to Earth after going into space. For this special test, Laika was brought from the streets of Moscow.
In this mission, Laika was being tracked by keeping her pulse and breathing in the spacecraft. Laika was very scared after the rocket took off. Not only this, his heart rate had also increased almost three times.
When it was tracked after 6 hours of orbiting, it was found that Laika had died. Not only this, some reports also say that the Soviet Union had sent another dog named Albina to do research in space during that time.
