At 9:07 a.m. Moscow time on April 12, 1961, a former Soviet astronaut named Yuri Alexeevich Gagarin rode on the Vostok 1 spacecraft Successfully went into space. He was the first person to enter space, realizing mankind's desire to enter space. Before him, humans had conducted many experiments. In order to verify the impact of space flight and the space environment on humans, animals were first sent up.

However, in the first few batches, because the spacecraft could not be recovered, most of the animal astronauts were sacrificed in the spacecraft. Rats, geckos, gerbils and snails were the first to be sent into space, but half of them died before reaching orbit. Among them, the first Earth Morning in space was not any of the above, but a dog. The puppy was a stray and was less than three years old when people saw it on the street.

There were nine other dogs with it at the time, and it was named Laika. Laika didn't understand what was going to happen next, but she knew she had a home and her wandering life was over. But this does not mean that it is lucky, because it has to undergo extremely rigorous training at the Institute of Space Medicine on the outskirts of Moscow. Of course Laika didn't understand why. What she knew was that she didn't need to find food by herself. After completing the training, there would be delicious food waiting for her.

After a long period of training, Laika became the best one, and at this time, it was already three years old. On October 4, 1957, the former Soviet Union launched the first artificial satellite in human history, and a month later the second satellite was about to be launched. This time this one is a little different, because there will be a guest on it, and this guest is the puppy Laika. Laika's excellent results make it the first earthly life to fly into space. Scientists have installed sensors on the surface of Laika's body and under the skin.

This is to monitor its heartbeat and breathing, and the data can be quickly transmitted back to the earth. Then, Laika was sent into a pressurized sealed cabin specially designed for it. This sealed cabin is at the head of the rocket, facing a camera. After everything was ready, Laika took off at 10:28 a.m. local time on November 3, 1957. As an animal, no one knows its mood. It is probably frightened, but it will leave a heavy footprint in human history.

A few hours later, Laika lost its life, the results announced by the former Soviet Union were. It completed a one-week flight mission and died after eating a highly toxic dinner at an altitude of 1,600km above the earth as planned. In fact, this was not the case. In 2002, the truth was announced. Laika suffered severe pain before her death. Just a few hours after flying into the sky, Laika died of fright and heat exhaustion. This is what many data show, published by former Soviet scientist Dimitri Malashankov.

Laika died in fear, but mankind has always commemorated it, even today more than 60 years later. American newspapers also deliberately called the former Soviet Union's satellite Laika's satellite. In 1957, the Soviet Union even issued a stamp for it. It has also become a trademark of cigarettes. In 1997, more than 40 years after his death, people built a memorial hall where he originally trained. So far, six songs have been written about it around the world.

Laika’s short three-year life has been remembered for more than 60 years, and humans will never forget it. Its body and space capsule are still flying in the orbit of the earth. Although it has only been up for a few hours, it has proven that mammals can accept the post-launch environment, paving the way for future manned flights. Nowadays, humans have not only completed space flight, but also successfully landed on the moon.
