A professor in the USA suggested that the American Space and Aviation Administration (NASA) may have transported microbes from the world to Mars with Perseverance. Suggesting that a possible life on the Red Planet can be taken from Earth, Prof. Dr. Christopher Manson warned that microbes can wreak havoc when they arrive in a new ecosystem and pose a major threat to astronauts’ health.
While expeditions continue on Mars, Professor of Cornell University in the USA. Dr. Christopher Manson questioned whether life discovered on Mars originated in NASA laboratories. Mason, of the Weill Cornell School of Medicine, said such a scenario could have happened despite the spacecraft assemblies that went through difficult cleaning processes in private rooms.
Manson explained that NASA’s Mars rover Perseverance was built in fully sterilized rooms with air filters and stringent biological procedures, and all equipment was cleaned before being added to the machine.
Stating that these methods restrict bacteria, viruses or fungi in the machines to be sent to a mission, Mason said, “However, it is almost impossible to reach zero biomass in a spacecraft. Microbes have been on Earth and everywhere for billions of years. “He can stay secretly.”
However, two recent studies by Mason showed how fast microbial species can grow in space, as well as how some organisms can survive the cleansing process and the journey to Mars.
“Apparently, cleanrooms can trigger an evolutionary selection process for the toughest microbes, and they may have a better chance of surviving a journey on Mars,” Mason wrote. Clean rooms in NASA’s Jet Propulsion Laboratory pose the greatest risk, as there is evidence of microbes with greater resistance to radiation and cold environments.
On the other hand, Mason added that if these microbes appeared on Mars, it would cause what researchers call “advanced contamination,” meaning that humanity could deliberately or unintentionally transport microbes from one planet to another. He warned that microbes could “wreak havoc” when they arrive in a new ecosystem and pose a major threat to the health of astronates.
On the other hand, Persevance landed on Mars in February and began looking for signs of life on the planet. NASA said it has taken extra precautions to ensure that all samples taken from Mars are safely contained. However, the scientists said they were aware that tests might need to be done to make sure the findings were of Mars origin.
The “Perseverance” reconnaissance vehicle, launched from the world in July last year, is equipped with a two-meter long robotic arm, 19 cameras and two microphones. The rover had landed on Mars on February 18, and it is scheduled for many years to research traces of possible microbial life on Mars.
