Does discovery of flowing water on Mars means that life even in microscopic form is possible ?
CWatters said:I think it's fair to say that over the past 30 years or so we have discovered that life on Earth can survive under surprisingly difficult/extreme condition's. I think you would have to be brave to rule out any possibility of life on Mars based on current knowledge.
I think it's reasonable to assume that the best conditions for life to originate would not be in the sort of environments where extremophiles are found on Earth.rollingstein said:Is there any reason to think that life need conditions more hospitable to originate than to merely to exist in?
Yes, there is strong evidence that liquid water once existed on the surface of Mars. Scientists have found features such as dry river beds, deltas, and minerals that can only form in the presence of water.
It is currently unknown if Mars can support plant and animal life. The planet's harsh environment, including its thin atmosphere and lack of a global magnetic field, make it difficult for life as we know it to survive. However, some extremophile microbes may be able to survive in certain areas.
Scientists are actively searching for evidence of microbial life on Mars. This includes analyzing samples collected by rovers and landers, as well as studying data from orbiting spacecraft. Currently, no conclusive evidence has been found, but the search continues.
It is technically possible for humans to live on Mars, but it would require significant technological advancements and a long-term commitment. The biggest challenges include creating a habitable environment, protecting against radiation, and providing a sustainable food and water source.
The potential for life on Mars is a major driving force behind future exploration and colonization efforts. Studying and understanding the planet's potential for life can provide valuable insights into the origins of life and the potential for life on other planets. Additionally, if life is found, it would significantly impact how we approach and conduct future missions on the planet.
