They have gone far beyond the neutron spectrometer work. The new instrument uses cosmic rays and gamma rays to identify many different substances---not just water.

A candidate for the 2020 mission.

A jack-hammer would be a nice addition to the payload. Get the crust off the rocks.

Hell lets go all the way and use some dynamite and stop this BLAH BLAH BLAH pussy-footing around before we all get too damned old and die!!

Silly Mars stuff will still be there.

Now 'THAT' is what the Martians need as a wake-up call from EARTH to get them up for us to see them. Sent those UK MOLES to Mars fast before the Martians escape.

Hurry, Hurry, Hurry! Everyone now...

Perhaps we have the history of a Lost Civilization,, buried deep beneath rock and radar.

Perhaps the last Martians had to move underground.

How can we know until we ''scratch the surface?''

One thing we dam shure know,,,, there is nothing on the surface but rocks and sand.

All repeat... ALL Future Missions should at least partially focus on underground.

Red Dragon to send 2020 mars rover samples back to earth?

On NASATV wwww.nasa.gov/ntv right now, a workshop about exploration of Mars.

"And a rock turner. GOTTA' have a way to flip the rocks over." Hort, I think the wheels on the rover will spin any way the operator wants them to spin. Rotate 5 one way and 1 the other way. With careful manuvering, we could FLIP rocks.

Space.com is reporting that NASA will announce the Selected Instruments for the Mars 2020 mission at a press conference today about 45min from now.

My initial reaction to the instrument suite was one of disappointment. No microscope with 1 micron resolution. No DNA/RNA detection using PCR. No wet chemistry lab.

It seems they have extended the habitability focus to looking for possible bio-signatures of ancient life. But such signatures are notoriously difficult to confirm even for ancient life on Earth, so any detection is likely to engender controversy.

If there are live microbes or spores at the Martian surface, even if they are EXTREMELY sparse, it seems like it would be easier to culture them and detect their presence than finding definitive signs of ancient life.

The sample cache mechanism is taking up a fair amount of landed mass on this rover although there are no plans to collect the samples. If this was omitted, maybe the extra space could be used for some life detection experiment.

On the plus side there is the Raman spectrometer and fluorescence analyzer

http://www.hou.usra.edu/meetings/georaman2014/pdf/5101.pdf

which can detect organics without the problem of being oxidized by the perchlorate.

There is also a trend to use onboard analysis for more efficient detection

and a new SuperCam

http://www.lanl.gov/discover/news-release-archive/2014/July/07.31-supercam-laser.pdf

which seems to be an advanced version of the ChemCam instrument on Curiosity.

A brief summary of MSL 2020 I wonder what they will call it? My shout would be "Fascination"

If names have power, I would call it "Discovery." Smile

On the instrument suite, I'm now thinking the sample cache was a brilliant tactic. If it picks up something interesting, it will be yelling "Come and get me."

Still disappointed that the new rover will
not have an auger, by auger, I mean a meter
or less,long,,2 to 4 inches diameter.

Similar to a post-hole-digger but, hollow in the center,,,, this is where the sample is
taken

Having done literally hundreds, ALL over WSMR,I can see where the process could easily
be made robot friendly.

Oh well,,, can't have it all.

The absolute most important thing of all is
a safe touchdown.
