If this underground lake will so exist, the water should be terribly briny -- a combination of metal, Ca and atomic number 11, that area unit all gift in Martian rocks -- so as to remain liquid. Even so, it's terribly fascinating implications for the chance of life on Mars, as life will exist on similar-type water bodies on Earth.
This detection has solely been created by one instrument, thus it is important to substantiate it before we have a tendency to all get our hopes up. Still, this sounds terribly promising, and it's exciting to consider the chances of what else may well be up there.
Thanks for very nice comment.It is true that only one instrument is responsible for the results but it is good as a start. At least now they know where to look and further research is much more important than confirmation that liquid water exist. It will be very exciting to follow research development...
But if this news is considered to be true, I hope it will be good news for us.
