NASA announcement 7th June
Discussion
Wonder what this one is about, participants include:
Jennifer Eigenbrode, a biogeochemist and geologist with expertise in organic and isotope biogeochemistry and interests in astrobiology. Her current research platform includes investigations of biosignatures in Mars analogs (rocks and ice)
Ashwin R. Vasavada researching the climate history of Mars
Chris webster: interests include Mars chemistry and habitability.
Paul Mahaffy, directory of planetary exploration.
I know it's probably evidence that Mars could have supported life in the past but how cool would it be if they've found a fossil.

Unless there are fossils everywhere there is or was water (as is the case on earth).
Curiosity was deliberately landed on a site that was thought to have a strong indication that substantial water had once lain there. The rover has more or less proved that there was at the very least a substantial lake at Gale and possibly even a shallow sea.
So, it's a good spot where some sort of fossils might be found.
In actual fact, I doubt if a fossil has been found - just some additional evidence for the presence of substantial water at that location at some time in the past.

I'm watching this with baited breath. I've got a very good idea what they'll announce, I doubt they've found a fossil though.
I'll be placing a bet that they've cracked a rock, examined the chemical data from within and found the remnants of amino acids that have been radiologically examined an traced back to an epoch when life could have existed on Mars.
If they have found a fossil, it didn't come from Mars. Hating to burst bubbles, but Mars is simply too small a planet for life to evolve on the planet. Energy sources are a bit thin on the ground, the best source of energy is the sun (obviously) and the next best source is geothermal.
Gravity acts towards a single point; the contents of a planet (eg earth) are pulled from the exterior towards the interior by gravitational forces, and causes it to get really hot. That b
ks they taught you in school - about the earth being boiling hot, and loads of volcanoes and dinosaurs - is bks. The earth was stone cold, and as it formed, gravity pulled all the bits together - mainly iron, nickel, silicates and hydrocarbon - and made it get nice and warm. Ergo - earth wasn't boiling hot and is cooling down - it was stone cold and warmed up.
That in turn generates heat energy, and can be used as an energy source for "life".
There's a probe heading to Mars later this year to study tectonic activity. If there's geothermal energy, that will manifest itself as tectonic plates andearthquakes marsquakes and make the possibility of evolutionary life occurring far more probable.
What's tickling me at the moment is this probe costing $$$squillions might simply show what can easily be predicted following the analysis of biological markers on the planet

Not sure what you were taught at school but we were taught that there was no Earth until gases, elements etc all coalesced to form the Earth and the heat was generated by this process, dinosaurs were real as are volcanoes last time i checked...

Some of the eco nut jobs in NASA are desperate to find some sort of life on Mars. It would give the excuse they need to avoid sending manned missions and they'd no doubt work to get the planet roped off forever.
Don't think the other nations will play ball. I think China would plant their flag everywhere they can and claim it is theirs.Maybe they have found the 9th planet. - https://www.space.com/38431-new-evidence-planet-ni...
