How can spaceships from another planet be sterilized?

We have been in touch with space for many years. Satellites, spaceships, sports cars, libraries… We sent everything. One of the most important goals of space studies is searching for extraterrestrial life.

The first thing to pay attention to when doing all these curious studies is, Spaceships are germ-free. Really, how is something this important achieved?

How can spaceships return germ-free?

Temperature is one method. Spaceship parts; at controlled humidity level, At temperatures of 110-200 degrees being heated. For the highest level of sterilization, this process can be done for several days. However, assembling the spaceship is not that easy. Instead, there is a more advanced method.

Spaceship parts are exposed to powerful rays, or radiation, that damage and kill the DNA of microbes. Against the odds of survival alcohol and hydrogen peroxide It is deleted with .

Other methods are also used to avoid leaving things to chance.

Use of heat, radiation and chemicals; It may be effective in getting rid of bacteria, but some bacteria It has very high adaptability and heat resistance. For these naughty people, a method called plasma sterilization is used.

The plasma method, invented to sterilize medical equipment sensitive to moisture and heat, eliminates microbes in a way. disrupts biological processes by bombarding and it damages the DNA of even those who are resistant to heat and chemicals and kills them.

All these methods are Taking bacteria from Earth to other planets It prevents research from being disrupted and prevents possible disasters that may occur on Earth.
