NASA believes that the first colonizers of Mars could pollute this planet.
Experts are already urging people who are working on drawing up programs for the development of the Red Planet to think about maintaining cleanliness on its surface. They warn that ignoring this issue could lead to Mars being as dirty as Earth. All research vehicles, scientists are sure, should be destroyed after the completion of their mission.
It is equally important to ensure that Earth's bacteria do not get to Mars, so all objects that are sent into space must be sterile. NASA has launched a program called Planetary Defense. Within its framework, specialists monitor the purity of objects that are sent from Earth into space.
The colonizers of Mars, scientists say, will have to follow the rules of disinfection. This will avoid the situation when terrestrial microorganisms get to the planet. According to experts, if a person brings bacteria from Earth to the Red Planet, they can affect his natural development.
