There is a creature in the world that can survive in space without oxygen. This microscopic creature is called Tardigrade.
Which have been inhabiting the earth's freshwater, oceans, and land for about 500 million years.
When faced with a dangerous climate change, such as a water shortage, it undergoes a process called cryptobiosis.
In the process of cryptobiosis, its metabolism becomes 0.01 and the water level in the body becomes 1%, in which case it stores water in its body. In other words, in cryptobiosis, there is an apparent death on the tardigrade.
Tardigrade was sent on a space mission🛰️ called Photon M3, launched out of Earth's orbit in 2007, and was not affected by gravity and the lack of oxygen delivered directly into space. Some tardigrades even laid eggs during this mission.
In addition, radiation has no effect on the tardigrade. It can survive even at -272 degrees Celsius. And can survive at 151 degrees.
