The Soviet Union was the first country in the world to launch artificial Earth satellites and one of the largest spacecraft launches, and its achievements in space had been remarkable throughout the world, with highly developed space science and technology keeping the Soviet Union at the forefront of space.
In the 1960s, the Soviet Union had been fighting for human space technology, and on 12 April 1961, a well-known Soviet astronaut, Gagarin, had become the first Earthman to enter space in the history of mankind, which was a remarkable step in its history.
But Gagarin was not the first creature to enter space, and in 1957 Leika, a three-year-old, entered space on Soviet satellite-2 on behalf of all mankind, a stray dog chosen by Soviet scientists.
"The stray dog" has spring too.
In the 1950s, with the flourishing of aviation in various countries, humankind was curious to explore the universe, and the technological power of development underpinned their dream of entering space.
However, the United States and the Russians dispute who was the first to enter space, and no one wants to be a pioneer in the face of an unknown journey to space.
After a stalemate, both countries had reached a mutually satisfactory outcome, namely, the selection of a dog to represent human beings into space, which would avoid human experiments and reduce the risk of human attack into space.
Soviet scientists believed that stray dogs had stronger bodies and stronger mentalities than domestic pet dogs, and then they went to great lengths to choose Leika.
They believed that Leika had survived the harsh conditions in the field and certainly had the aviation test.
Before launching Leika into space, Soviet scientists first conducted a series of high-intensity training and appraisals of Leika.
Following a rigorous examination, Leyka fell short of expectations and was able to bear it together, becoming a real “space dog”. This is probably the brightest moment of Leyka's life.
On 3 November 1957, Leika welcomed its high-light moment, when it boarded the spaceship Satellite-2, becoming the first living creature on Earth to enter space. Leika began her space trip with the eyes of all mankind.
"Ascotch Dog"
Leika represents the first time that all humankind has entered space, and the scientists of the Soviet Union have taken it very seriously. They had perfect protective measures for Leika and had also implanted a sensory chip in it to facilitate the measurement of Leica ' s breathing, heartbeat and blood pressure to ensure its vital characteristics.
Leika was placed in a sealed chamber by Soviet scientists, in which the Soviet scientists adjusted the appropriate pressure and temperature and were supplemented with energy to ensure the safety of the living environment of Leika.
However, after Leyka entered space, he died only four days in space.
The official Soviet response was that scientists on the ground had discovered that Leyka was healthy in the space environment through remote surveillance and the sensory chip in Leyka, and that it was able to travel and eat in a sealed chamber.
The Soviet official also declared that, because Satellite-2 had not designed a safe return device, they had prepared a highly toxic meal for Leyka and decided that Leyka would die, which was why Leyka died.
On 14 April 1958, a satellite carrying Leika crashed on Earth as a result of natural energy depletion, and Leika's bones were burned with the satellite crash, which killed Leika for a short life.
Leyca's experience was a little flattering, but more people are wondering if Leyka really died from taking a very toxic diet? The mystery of Leika's death lies in people's minds, and the truth comes out.
Leyka's death mystery.
In 2002, a space conference was held in Houston, United States, and the former Soviet scientist Marasankov, who had participated in the Leika space experiment, was present.
At this meeting, Marayamakov revealed the real cause of Leyka ' s death, revealing that the Soviet response to the Leyka incident was a great lie.
According to Marayamakov, the temperature of the sealed chamber where Leyka is located has been increasing at an altitude of more than 1,000 km from the ground, and the cooling technology previously installed by scientists has not solved the problem of the temperature rise in the chamber.
On the ground, scientists were able to detect a sharp increase in the Leika heart rate by monitoring the sensory chips implanted in Leika.
The heart rate of Leika was detected 100 times a minute on Earth, and after Leika entered space, it was detected more than two hundred and forty times a minute, more than twice that rate, exceeding its carrying capacity.
Five hours after the satellite entered orbit, Soviet scientists were gradually unable to monitor Leika ' s heartbeat and pulse, and seven hours later scientists were no longer able to monitor Leika ' s vital features.
After four rounds of satellite orbiting the Earth, Soviet scientists have largely confirmed Leika ' s death.
That is to say, it is not Leika who spent four days in space and died because, hours after the spacecraft had been launched, his body could not withstand the heat and pressure.
While the death of Leika is a cause for consternation, more people remember Leika and go and remember him.
In commemoration of Leika, the Soviet Union issued stamps on Leika during the year that Leika entered space, and soon again there was a cigarette branded Leika. Leyka ran through the entire Soviet society at the time, and that is precisely how the Soviet people commemorated it.
In 2007, in order to better commemorate Leika, Russia built a statue for it in Moscow, the capital, at the Space Research Institute entrance.
The statue of Leika is made of the hand of man and the hand of Leika, which stands on the hand of man and symbolizes that man will always hold Leika in his hand.
On 3 November of each year, the Russian population also spontaneously commemorates Leika, which some satellite space companies treat as a major day. “Leika” has become a beacon on their space path, after all, the first creature to enter space.
The fate of Leika is undoubtedly tragic in terms of the development of the space industry, which, despite its sacrifices, has provided invaluable experience for people to board space and has contributed greatly to the development of the space industry.
From a emotional point of view, Leyka's fate is tragic. It's just a mouse in the history of human space development. No one in the United States or the United States is willing to do it. When the first person to board space, Leika's fate was doomed to death.
In 1961, cosmonaut Gagarin became the first Earthman in the world to make it into space, after which Gagarin joked, “I simply cannot understand who I am, and the first person in the universe is the last dog.”
That kind of joke speaks of the danger of him going into space, like Leika.
