Ok. Dish. Why do you think life is currently on Mars?
It's a belief I have that's steadily got stronger over the years thanks to the excellent work done by NASA and their rovers , we know that Mars once
had a magnetic field and a thicker atmosphere but now we know it also had significant quantities of water at its surface , all pointers to a
hospitable place for life .
Here's an image created using data from the MARSIS radar on Mars Express of a former ocean of Mars .
was released last month that suggests life may have started on Mars before
it did here on Earth and got transported from there to here , if that is the case then are we to believe that all life on Mars ceased to be because of
the apparent loss of its water and magnetic shield ? , or is it more likely that it migrated underground to cave systems that were created by water
using the same processes that occur here on Earth .... I find that a likely scenario .
Prof Benner explained: "It’s only when molybdenum becomes highly oxidised that it is able to influence how early life formed.
"This form of molybdenum couldn’t have been available on Earth at the time life first began, because three billion years ago, the surface of the
Earth had very little oxygen, but Mars did. "It’s yet another piece of evidence which makes it more likely life came to Earth on a Martian
meteorite, rather than starting on this planet."
Early Mars is also thought to have had a drier environment, and this is also crucial to its favourable location for life's origins. "What’s quite
clear is that boron, as an element, is quite scarce in Earth’s crust," Prof Benner told BBC News, “but Mars has been drier than Earth and more
oxidising, so if Earth is not suitable for the chemistry, Mars might be. "The evidence seems to be building that we are actually all Martians; that
life started on Mars and came to Earth on a rock," he commented
And of course we have the image of possible flowing briny water on Mars today , I think it's possible that there are underground pools in those cave
systems kept liquid by heat from the planets core , again a suitable habitat for life .
Of course I could be wrong and Mars may well be a baron lifeless planet but I believe that our red neighbor holds many surprises for us and ET
microbial life is top of the list
