I do know
Actually I doubt they will ever find life on Mars. Maybe fossils, but
just because the planet once had water does NOT mean life automatically
followed. Mars was not like Earth and never will be.
NASA is wasting its time focusing so much on Mars and searching for
life there. The place didn't have canals, didn't have ancient civilizations,
didn't have lichen, and now it looks like it doesn't even have microbes.
So what's it going to take to get off the Mars Life train and put all
that money and effort to somewhere more viable, if alien life is what
you want?
