NASA is close to discovering life on Mars but the world is not ready for the revolutionary implications of the discovery, says the agency’s “chief scientist”. Dr. Jim Green warns that both NASA and ESA rovers can find evidence of life only months after Mars arrives in March 2021. The ExoMars rover also called Rosalind, according to British chemist Rosalind Franklin, will be searching for 2 meters underwater. The samples will be crushed and analyzed for the presence of organic matter in a mobile laboratory. Dr. Green likened the potential discovery to when 16th-century astronomer Nicholas Copernicus stated that the Earth orbits the sun. “It will open up a whole new line of thinking. I think we’re not ready for the results, “he told The Sunday Telegraph. “I’m worried about that because I think we’re close to discovering and making some statements.”
NASA’s Mars 2020 rover will dig in rock formations on the planet before sending samples back to Earth, bringing Mars material to Earth for the first time. Dr. Green adds that the discovery of life on Mars will give scientists a new set of research questions. “What comes after that is a whole new set of scientific questions. Is it kind of like us? How are we connected? ”He says. “Can life travel between planets or do we have a spark and a real environment to make life – like us or not like us – based on the chemical environment in which it is located?”
Labor published this month also claims that Venus may also have been inhabited 2 to 3 billion years before its atmosphere became incredibly dense and hot 700 million years ago. According to Dr. Green research suggests that there could be civilizations on other planets. “There is no reason to think that there are no civilizations elsewhere because we find exoplanets everywhere,” he says.
His comments came less than 24 hours before tech entrepreneur Elon Musk unveiled a new SpaceX spacecraft designed to bring manned and cargo to Mars or other planets in the Solar System before returning to Earth. According to Musk, the company’s spaceship is essential to the viability of the spaceflight because of the ability to use the spacecraft multiple times. The ship is expected to fly for the first time in about two months and reach nearly 20km before landing on Earth.
Hundreds of millions of years ago on Mars there was a zone suitable for the survival of microbes, according to new findings from a science team led by Jesse Tarnas of Brown University in Providence in Rhode Island, USA.
The analysis is based on data obtained from the Mars Odyssey orbital probe.
According to scientists, there was a sufficient amount of hydrogen on the Red Planet to maintain that “primitive flow” through life. a process of “water radiolysis”.
These processes can occur on a larger surface, and the energy released thereby can keep primitive microorganisms alive. Similar processes have occurred on Earth millions of years ago.
According to scientists, lithotrophic organisms can also exist at a depth of 1.5 kilometers underground, according to a paper published in the journal Science and Planetary Science Letters.
