Re: Past and Present life on Mars

There seems to be a distinct danger that we shall never find out about Mars life as we shan't be allowed to go because we might contaminate Mars, so threatening putative Mars organisms with Earth organisms.
This view ignores the exchange of meteorites between the two bodies over the past three and a half billion years or so.

BITD, that view was only held by extreme "Ecofreaks." It's now become a bit more popular, but remains irrational.

Re: Past and Present life on Mars

The latest video from Anton Petrov is very interesting.

Something on Mars is generating complex organic molecules.  These are rapidly destroyed by the highly oxidising conditions on Mars.  Their existance can only be explained by some mechanism that continuously replenishes them.

"Plan and prepare for every possibility, and you will never act. It is nobler to have courage as we stumble into half the things we fear than to analyse every possible obstacle and begin nothing. Great things are achieved by embracing great dangers."
