The tardigrades are critters that can survive extreme conditions, but earlier studies show that they are indestructible. These are the hardest critters that can be found in the Animal kingdom.
They are microscopically visualized organisms, and these are one of the creatures that can survive any kind of worst situation. They can found in volcanoes. They can survive in a vacuum, can survive in Antarctica, and they have survived even after remaining frozen for three decades.
Although earlier studies say that they are indestructible, recent studies proved that they could also withstand up to some limited situations.
To prove their survival limits, A canister filled with tardigrades was shot with a gun at a different speed. It was seen that when shot with a gun speed of up to 900 meters per second, they were able to make it, but at any higher speed than 900 meters per second, they could not survive.
When they were shot with 2000 mph speed, they experienced 1.14 gigapascals of pressure which is equivalent to the standing of 40,000 people on one’s back.
The tardigrades have other names like Moss piglet or water bears. They can withstand temperatures up to 458 degrees Fahrenheit. They also have the potential to survive radiation since they go into hibernation and hence withstand temperature. Moreover, they can survive in the absence of Oxygen. And they remain in a state called cryptobiosis.
As they have this much survival quality, they were sent to the moon by Israeli spacecraft. The spacecraft crash-landed on the moon, but still, scientists believed that it would survive.
But scientists still had doubts over its survival, so they performed an experiment where they shot the tardigrades with high-speed guns and noted that they could not survive over 900 MPs speed. Hence, the crash landing of the spacecraft would definitely have killed them.
Since they were not able to survive the crash landing on the moon and hence it can be predicted that they can not survive the asteroid collision with other planets.
