Finding signs of alien life on other planets has been of great interest to explorers and scientists. However, so far not much has been achieved. But scientists haven’t given up on their search and seem determined to unravel the mysteries surrounding our solar system. A promising attempt to answer the most vexing questions: Are we alone in this world and are there or have ever been more extraterrestrial species? Are other planets capable or capable of supporting spirits? In a recent interview, Jim Green talked about his COLD scale and explained how we can reshape Mars to make it habitable for humans.
green join NASA In 1980 and since then he has taken part in key roles in many missions and experiments by the space agency. He has helped NASA perform a variety of complex tasks, including understanding Earth’s magnetic field and searching for life Mars. After spending four decades at NASA, during which 12 years he headed the Division of Planetary Sciences, Green retired from the agency in the new year. One of his brilliant proposals was the “Confidence in Discovering Life” or the Cold scale. Green suggested that humans could someday live on Mars if we created a giant magnetic field on the Red Planet to prevent the Sun from stripping the atmosphere there, increasing the temperature on Mars.
Mars is hard and cold because its thin atmosphere is made up of 95% carbon dioxide. On average, this arid planet has a temperature of around minus 60 degrees Celsius. During winter, temperatures near the poles can drop to 125 degrees below zero.
Against this backdrop, how well does Green scale work? He was asked about it during the interview New York TimeOn his COLD scale, Green says, the odds of living are measured from one to seven, where seven means life. Explaining its importance, he said two years ago, some scientists said they had discovered phosphine on Venus. To them, it is huge but on the scale of COLD it is “one”. Later, they realized that there was contamination in their signal, and that what they found was not even phosphine.
A lot of methane has been found on Mars. “(But) we are only at COLD level 3.”
Even though NASA has been exploring Mars since 1976, is it surprising that we haven’t found life on the Red Planet yet? “Yes and no,” said Green. He said that scientists have made great achievements since the beginning. For example, now we know that Venus It was once a blue planet with a vast ocean. “Maybe he already has a life,” he added. Likewise, Mars was once a blue planet.
Talking about his proposal to create a giant magnetic shield between Mars and the Sun, which would allow the red planet to trap more heat and increase its warmth, he said, “It’s possible.” He added that Mars would repair itself with increasing pressure and temperature. Higher temperatures and pressures will allow us to start the process of growing plants in the soil.
He said he was trying to get his hands on the “paper” he had been working on for two years. However, he continued, it would not be well received by the planetary community who “do not like the idea of reclamation”. But Green says he believes we can also transform Venus with physical shields.
