NASA's Curiosity rover has discovered ancient organic molecules on Mars. That plus the methane is strongly suggesting that life may have existed on Mars back when liquid water existed on the surface.
NASA's Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on the Red Planet. While not necessarily evidence of life itself, these findings are a good sign for future missions exploring the planet's surface and subsurface.
The new findings – "tough" organic molecules in three-billion-year-old sedimentary rocks near the surface, as well as seasonal variations in the levels of methane in the atmosphere – appear in the June 8 edition of the journal Science.
Organic molecules contain carbon and hydrogen, and also may include oxygen, nitrogen and other elements. While commonly associated with life, organic molecules also can be created by non-biological processes and are not necessarily indicators of life.
"With these new findings, Mars is telling us to stay the course and keep searching for evidence of life," said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters, in Washington. "I'm confident that our ongoing and planned missions will unlock even more breathtaking discoveries on the Red Planet."

How many stories have there been about methane found on mars? Oodles!
From what we know, mars was once much nicer than it is now. On Earth, we find life virtually everywhere. I suspect that once we can get some samples back from mars (or have an actual lab on mars), we will find life there too.
I would be shocked if mars was completely sterile. I also think that the lift we do end up finding on mars will be almost identical to life found on earth (ie. it will fit into our existing classification systems).
But then again, I don't really know anything about biology or geology. ¯\_(ツ)_/¯

Basically, TFS and TFA say, "Hey, we found a hydrocarbon on Mars!" An indicator that we already knew existed. Now - if/when they find CHO compounds undergoing some chemical changes, some excitement may be justified. Maybe. A CHO compound is probably an indicator that there is life around, and watching it undergo some kind of chemical reaction will probably reveal that life. Then again - maybe not. We can't yet rule out the possibility that CHO's form and then oxidize in the absence of life. Not yet, anyway.

Did anyone think the Administrator would say anything else?
Seriously, this finding was telegraphed, then embargoed, then announced with great fanfare. Just like the blueberries, which were also signs of life. Molecules buried in rock. In all these years, nothing approximating a fossil of moss or even a sea bed slime.
OK. Molecules in rocks. But it seems a tad over-hyped if you ask me. A budget play?

I am pretty sure that "I hear Mars speaking to me" is a symptom of a psychiatric disorder.
And if not, then what was Mars "telling you" when the when the Mars Climate Orbiter [nasa.gov] burned up entering the Martian atmosphere or when the Mars Polar Lander [thecanadianencyclopedia.ca] crashed in flames? "Go die in a fireball?"
I humbly suggest we, as a space-going people, not ascribe anthropomorphic statements to low-survivability planets in general, that we not be discouraged by what they predominantly have to say.

Well for the polar lander, the Wikipedia page says that chronic underfunding and mismanagement were the underlying causes of failure there. So maybe Mars is telling us to stop being so incompetent about management and funding.
And the climate orbiter I think was the one that failed because the teams didn't know what units they were using (one metric, one English, with the data given without any units, and the units merely assumed). So on that one, maybe Mars is telling us to not be stupid and to stop using archaic measurement systems and to always specify units no matter what system you're using (this is something I was taught in first-year engineering school!!!).

So in that vein, for Curiosity's mission to determine habitability and life factors eventually finding hydrocarbons in 2018 after landing in 2012, it is maybe saying "Years after your lander was supposed to be long dead, you finally found some molecules that might be interesting and might not."
I can actually see hearing that as "stay the course", like Zurbuchen did. It's encouraging. And maybe the fiery deaths of the polar and climate landers were saying "Mars could use some global warming", which would sure make it more comfortable for explorers, settlers, and castaways from Earth.

Wouldn't it be funny if after all this time, the lander is dead and they've got an AI computer in some room feeding the other computers fake data showing results.

Roy: "We set up a voice activation system on your computer... i think you're going to like it...might just take a while to get the pitch right on the voice but none the less, go ahead."

My guess is that interplanetary microbes that haven't evolved near humans won't be harmful. The diseases that isolated human populations have spread between themselves throughout history were still evolving alongside humans on either end.

My guess is that they won't be "directly" harmful because they haven't evolved near earth-life, however, precisely _because_ they haven't evolved along with earth life or in earth environment they may have very different metabolisms and biochemistry, and some of the chemicals they produce or rely on or excrete may well be harmful. Consider clostridium botulinum as an earth bound example - it ain't the bacteria that gets you its the neurotoxin it produces. My gut feeling is that this type of thing is far more likely than an attack from the microbe itself.

Thank you. That is an excellent answer.
I'm thinking that some other life, based on long chain hydrocarbons can probably eat us, and we can eat them. Maybe not all. But it would seem likely that some could be. If not most. I'm no biologist or organic chemist (software developer here), but it seems that organic chemistry, with the same periodic table, probably works the same everywhere. (Hey, 19th century chemistry works on Mars! Who knew!) Long chain hydrocarbons are formed. More and more complex molecules are formed. Eventually amino acids. Proteins. And up and up to bigger and better structures until you get to DNA.
These atoms only form certain molecules. These molecules only fit together certain ways. All planets start out with the same periodic table of Lego bricks. If you keep jumbling the Lego bricks together in an endless ocean stew, you eventually form the same things.
