A scientist at Southwestern Research Institute created an atmospheric model on Mars to determine that the saltwater bag on the Red Planet could not be inhabited by life as we know it on Earth.
Due to the low temperature of Mars and very dry conditions, a drop of liquid water on its surface will immediately freeze, boil, or evaporate unless the salt drops dissolve in it.
This salt water will have a lower freezing point and will evaporate more slowly than pure liquid water. There is salt everywhere on Mars, so salt water can form there.
“Our team is examining certain areas on Mars – areas where water temperatures and accessibility restrictions allow replication of known terrestrial organisms – to determine whether they can be inhabited,” Dr. Alejandro Soto, a senior researcher and researcher who wrote this research.
“We use Mars climate information from atmospheric models and spacecraft measurements.”
“We developed a model to predict where, when and how long the salt on the surface and flat surface of Mars will be stable.”
Very dry conditions on Mars require lower temperatures to achieve high relative humidity and tolerable water activity. This is a measure of how easily the water content can be used for hydration. The maximum expected temperature of salt water is -55 F – at a theoretical limit for a lifetime low temperature.
“Even extreme life on Earth has its limits, and we have found that salt from certain salts can cause liquid water to be more than 40% of the surface of Mars, but only seasonally for 2% of Mars years,” Soto continued. It will obstruct life as we know it.
While pure liquid water is unstable on the surface of Mars, models have shown that salt water that is stable from the equator to the high latitudes of the Martian surface can form and last for several percent years to six consecutive hours, a wider area than before thought. . However, the temperature is far below the lowest temperature to save lives.
“This new result reduces the risk of exploring the Red Planet while contributing to future work on the potential for habitable conditions on Mars,” Soto said.
