We all know that human beings can enter space now, but probably few people know that the first creature to enter space is a dog named Leika, which was trained by scientists of the former Soviet Union and put into a satellite to fly into space.
In fact, the scientists did not prepare to send it back to earth when they put it on the rocket, because the aircraft carrying Leica had no return device at all, and poison was added to Leica’s dog food. According to the scientists’ plan, it was allowed to survive in space for a few days and then euthanized. In the original plan, Leica had a chance to return to earth, but because the former Soviet Union wanted to launch on the 40th anniversary of the October Revolution, it had to change the original plan.
Lycra is tightly locked by a chain. The food in front of it is like jelly. A carbon dioxide collector, an oxygen generator and an electric fan are designed in the satellite module to cool down. After the launch of the artificial satellite, through the data sent back by the medical sensor tied to Leica’s neck, people can see that soon after it left the ground, the pulse rate rose sharply to three times of the normal rate. When it entered the space and was in the weightless state, the pulse rate slowed sharply, then accelerated sharply, and slowly disappeared completely. In the end, people rescued Lycra three times through the remote control centrifuge, trying to recover Lycra’s heartbeat, but there was no effect.
In November 1957, Soviet officials announced that Leica died peacefully after living in space for a week. But the truth is: according to the data sent back to the earth by the automatic measurement recorder on the satellite, shortly after the launch of the satellite, the temperature and humidity of the space capsule kept rising, and the cooling fan didn’t work at all. When the temperature in the cabin reached more than 40 degrees, Leica’s heart beat faster again. Between 5-7 hours after the launch of the satellite (the fourth flight around the earth), there was no life signal from Leica on the ground. That is to say, after leaving the earth, Leica died painfully in the heat and pressure in just a few hours. Five months later, Leica’s aircraft fell to the United States, and its body was disintegrated in space. Poor little dog Leica never returned to earth, and is still floating in space.
