If tardigrades can exist at -270 degrees, I think it's highly likely there's life on Mars in one form or another.

Is there Life on Mars?

Are we about to find out something amazing? Life changing or just thought provoking?

My guess is that they'll only announce finding more evidence of something (water, past climate conditions etc) on Mars that might have been able to support evolution of life sometime in the past.

Im picking they found evidence of past life. Not a big deal IMO. Mars was very like Earth, liquid water, same elements, rotating iron core, volcanoes, and electricity from weather. It must have had life. Then the core stopped, it cooled, atmosphere blew away, radiation got in.

I feel like that myself most days!

The remains of some ancient civilisation - plastic bags! 

It's life Jim but not as we know it.

Of course there is. Here is a documentary...

Regardless of tomorrow mornings major announcement by Nasa - it was at least a great song!

Don't think there'll be anything new that we haven't heard before.

Didn't know it's a song!

Dammit, I was gonna post that!

IMO that would be a very big deal indeed.

Would probably create a debate about whether life on adjacent planets evolved independently or if it was panspermia, and I guess that would be very hard to resolve.

True. They would need DNA from it?  IMO it is all based on universal beings as such. Our solar system has the same elements as the planets have the same source. Assume other systems are the same, depending on the power of the supernova that created the elements. Life forms would vary a lot, as they do here, depending on the environment

I sung the thread title to myself.

Now it is stuck in my head.

So if it was DNA based, and even if that DNA had shared sequences with life on earth, that doesn't "prove" it didn't evolve (more correctly abiogenesis didn't happen) independently.

It could be that for life to happen in what we call "goldilocks zones" - it most probably has to happen the same way it did here.
