Well, if I were one of the scientists who selected this landing site based on what was expected at Mount Sharp I would be getting a little worried. We're seven months into the 2 year mission - and Mt Sharp is a VERY long way away, at least a years driving I think.

Well, that was disappointing.

Only the engineering cameras raw data are in the first Curiosity Analyst Notebook release - and they are not readable by my imagej PDS plugin. ( NASAVIEW can read them. )

I repeat: NONE of the science data - contrary to the laws of the United States and bought and paid for by the American public - are in the release.

Another example of the growing lawlessness in the USSA. Booo!!

I was a bit disappointed as well but they did release the REMS data which I scheduled myself to convert into something usable for next week (no time over the weekend) - lets see what the humidity sensor really shows...

Regarding that, I guess here is another patch of frost upper left in the shadow of that rock on this sol 137 morning observation (8:37 LMST):

Looks like frost can be observed quite regularly in the morning and evening hours in and around the Yellowknife Bay area - now I wish we could correlate this with the according full REMS readings...

Wonderful image, MPJ. I had my doubts about the previous example but this one is crying out frost. A correlation with the REMS humidity readings would be most welcome---if they are there in the PDS release.

The above National Geographic article seems a little more pessimistic about the potential for delay. But from the Craig Covault article it looks like they might have already had some data before this malfunction occurred.

Nice find Re 250 MPJ! Is that damp soil just below the frost?, or am I seeing shadow? If it is damp soil, the frost is melting and running downhill a bit before evaporating.

Does anyone here know what the scale of this image is? Is the rock face 3' or 3"; I have no idea.

Sol 0137 3D enhanced difference false color of possible frost under a rock in Yellowknife Bay:

My best guess is that the bright area under the rock is rock in sunlight on the other side of the rock - and not frost in shadow under the rock.

The bright color "under" the rock is close to the color of the rock in sunlight.

Also, in 3D, the edges of the bright areas "under" the rock look very much like the edges of dark rocks under the rock - not like the edges of bright areas under the rock.

3D is always better.

I think Horton is right, so this time not light shining trough but low sun angle hitting a raised surface in the shadow area of a bigger rock. This kind of imaging (low sun angle) can be very deceptive I guess. Still I wouldn't rule out frost completely - even if it was a raised edge(rocks) frost would aid in making it that reflective in the shadow of the big rock. Confused
Nevertheless I spotted some more but far smaller suspicious white flecks in that panorama but without comparative later (midday-) images and/or ChemCam data (luxury I know) its really hard to say something definitive like in the former example.

Thanks for the 3d Hort - but it still looks different to me under the rock than from the sun's glare coming off the top. And a different texture? as well. You are likly right and my eyes are getting pretty old to boot. I'm getting sore eyes from studying MPJ & your images. Appreciate the work from both of you.

Cosmic Ray may have caused the Computer glitch on Curiosity it's going to take a while to get it up and running again but nothing to worry about at this stage other than lost mission time.

I wonder how long will it take them to identify all those broken up pieces of heavily structured and layered rocks to be carbonate rocks? Maybe the upcoming LPSC? Smile

The Rocknest pano again shows loads of stuff which is suggestive (to me at least) of a shaken and broken up ancient cold water coral reef with its fossilized pieces now scattered and mostly buried beneath the top dust layer in this area...

MPJ: your 250, so interesting feature on that rock.

These rocks are amazing because they show signs of [insert chemical structure here] which indicates flowing water on Mars at some point in the distant past. This sample has qualities just like rocks on Earth that have been formed by flowing water. This means Mars was once [soaking/drenched/any-other-very-wet-adverb with water] at some point in the distant past. Water is a key ingredient to life as we know it. This warmer and wetter Mars could have been habitable by microbial life.

[Pathfinder/Spirit/Opportunity/Curiosity] are on a __ [month/year] mission to investigate whether Mars was once a warmer and wetter place so scientists can build upon prior speculation and further speculate about whether there was, or is (!), microbial life there while getting no closer to actually answering that question due to the current snail's pace rate which only yields the same major, groundbreaking water discoveries.

Water, water, everywhere; nor any drop to drink.

Sorry for the spoiler.

The planetary scientists seem to want a sample return mission to be the one that discovers life.

But the only way they will get a sample return mission is if MSL comes up with at least a strong presumption of life.

I wouldn't hold my breath for us to hear about that presumption, that's for sure. MSL isn't looking for life, they say. Sure, the third "goal" is "identify features that MAY represent the effects of biological processes," but when you look at all the other goals, you'll not find another where they articulated so pendulously.

That wasn't an accident. They chose their words wisely and intentionally. It's totally noncommittal. They wouldn't have put biosignatures as a goal if it wasn't one they could not attain.

When it comes to reduced funding, an agency like NASA has to stack the deck for itself to ensure future funding. The last thing you do is make one of your top goals for your top mission, which will serve as a measure of mission success or failure, one you MAY find.

They've likely already identified numerous biosignature features with prior missions. Now, they can tell us about a warmer Mars drenched with super-mega amounts (it was just 'mega' before MSL) of gushing AND gently flowing water that was once habitable (wow!) with organics and where there's water, there's life. Bam. Curiosity is, to quote Borat, "great success!" Humans are natural explorers. Who wouldn't want to keep looking, right? There's all is water! Water everywhere! Water is life! COULD there be life? MAYBE! Just think about all at water.

They'll get their sample return. Can't wait until 2030 to see it.

I really wonder how long those planetary scientists will keep the silence and the "eyes wide shut" stance in relation to all the latest imagery without looking like morons on the long run... Smile

I mean one can choose to believe in a god just like to believe in mere coincidence on Mars in order to not attack a current paradigm... Razz

I say a sample return mission is not necessary to robustly confirm past/present life on Mars - its just about good/clever use of the available (robotic-) assets and to dig the right conclusions from ALL available information (past/present) - not only a pure geologic subset.

Barsoomer; Hope this is not another false alarm like all the previous ones that announced another small find confirming ancient water on Mars. But being an eternal optimist, I am betting that this time they have found real organics in that grey rock.

I had thought that they would have reached this milestone within a couple monts of curiosity landing. But als that was not to be.

So where do we go from here? Liquid water? Wonder what the RH measurements say? The Temperature and pressure measurements say that frost should exist fairly frequently at yellowknife bay since above triple point conditions from the REMS data seem to be the rule rather than the exception on a daily basis.

Levin and his people must be on tenterhooks waiting for that press conference.

Maybe, LWS, but remember how the drill bit wasn't "properly sterilized." Water could allow those Earth microbes to survive, remember?

So, we get pendulous results yet again.

Organics, wow! But, wait, they COULD be from Earth. Crap. But they COULD be for Mars. Wow! Are they Martian organics? MAYBE! But maybe not. But we know the water is Martian. Where there's water, there's life. Life is made of organics. So, they COULD be Martian. Maybe we will find out some day if we keep exploring!

So this "potentially historic" announcement will not historic at all because of the "potential" that the organics are from Earth. Thus, it's more speculation with no answers. It will be historic on in retrospect. Flashforward to 2038: "Oh yeah, they had the data in 2013, they just didn't know it yet."
