An analysis of 20 years of spacecraft data from NASA dismisses the possibility of terraforming Mars، a hypothetical process of making the Red Planet hospitable like Earth، as Technical Times said. Ultimately، the study ruled that there is an inadequate supply of carbon dioxide on Mars to create an atmosphere that can sustain life. The team of scientists who worked on the analysis said the CO2 on the planet is not thick enough to produce liquid water on its surface. The team tallied all the possible scenarios of releasing enough CO2 on Mars، but it all leads to the conclusion that there is no available technology on Earth at present to make the terraforming possible. Elon Musk disagreed. In a tweet، he said Mars has massive CO2، and it can only take either an artificial or natural fusion to release them. For the study، published in Nature Astronomy on July 30، the team of scientists analyzed the quantity of carbon-bearing minerals and the presence of CO2 in polar ice using data from NASA Mars Reconnaissance Orbiter، Mars Odyssey spacecraft، and data on why ancient life forms did not survive on the Martian planet.
The scientists found that Mars has enough water ice that can create water vapor، but low temperature prevents the water ice to vaporized and produce CO2. Releasing chlorofluorocarbons or other fluorine-based compounds may raise the atmospheric temperature، but that will require a large-scale manufacturing process that is، at present، impossible to do.
