Is Mars the Possible candidate to become a habitable planet?
A recent study by the NASA Institute of Space Science suggests that it very well could be. The study was led by Dr. John Johnson of the University of Arizona. His research was part of a mission to study the Habitability of Mars, specifically at its poles and at its equator. This would help determine if there is water present in the atmosphere and how much.
If there is water present, would it be suitable for life forms. Dr. Johnson found that there are trace amounts of water ice existing on Mars. If there is ice, it would be thin and invisible under the snow. That would mean that it would be a cold planet, much like Earth. However, it is not cold enough to be a suitable abode for microbial life.
In addition, there are large quantities of nitrogen and sulfur, which are present in the soil of Mars. It would be extremely hostile to microbial life and quite inhospitable to animals, and plant life as well. Mars does not have enough air pressure to hold these gases against the Martian atmosphere. The atmosphere would become too thin to support any life. Which means that there are no prospects for life on Mars at the moment.
