Aftermath of firing Curiosity's laser at Martian dune sand:
A merged focus image from the Mars Hand Lens Imager (MAHLI camera) of an array of laser strikes across the crest of a sand ripple called 'Ripogenus'. A series of pits can be seen that have formed as the result of successive strikes by Curiosity's powerful laser.
The process is called Laser-Induced Breakdown Spectroscopy (LIBS) The technique fires pulses of a laser at a target such as a rock or sand. Energy from the laser excites a pinhead-size spot on the target into glowing, ionized gas called plasma. Spectrometers in the instrument analyzes the spectrum of light emitted by the plasma to identify chemical elements in the target. Different elements glow in different wavelengths, or colours, the resulting data is used to accurately determine the mineralogy of the target.
I have added a 3 centimeter scale bar to the bottom of the image based on the cameras focus motor count, I have also processed a 1 millimeter checkered scale around the edge of the image. View this image full screen to see the fine detail of the sub-millimeter grains as well as the variation in grain shapes as well as the different colours / translucency present in this small sample

Sol 1639: Onward to Ogunquit Beach

16 March 2017

Planning was challenging this morning because of some network issues at JPL, but the team figured out how to work around the problem and still managed to put together a good plan! We’ve been at Stop 3 of the dune campaign (now known as “Southern Cove”) for a couple of sols, so in today’s plan it’s time to move on.
On Sol 1639 the rover will begin by retracting the arm and doing some drill diagnostics before taking MAHLI images of the targets “Greenvale Cove” and “Holmes Hole”. After that, we have a remote sensing science block with a Navcam movie to watch for clouds above the crater rim, followed by a Mastcam change detection observation of “Holmes Hole” and a ChemCam observation of the disturbed sand at “Greenvale Cove”. Mastcam will also document “Greenvale Cove”. After the remote sensing is done, Curiosity will drive toward Stop 4 (“Ogunquit Beach”) and collect some post-drive images.

PS: "ofset" s lokacije 1642 na lokaciju 1643- snimanje stereo snimka bazne linije s pancam. Ovaj način se  koristi po prvi put, koliko je meni poznato. Dobra ideja u svakom slučaju.

Sol 1644: Staying put

21 March 2017
The Sol 1644 plan focuses on arm activities, because the volume of data expected to be relayed via the MRO and Mars Odyssey orbiters in time for planning tomorrow is too small to allow both a drive and drill diagnostic tests.  So the tactical science team took advantage of the opportunity for contact science by planning APXS and MAHLI observations of bedrock targets named "The Hop" and "The Horns."  But first, ChemCam and Right Mastcam will observe The Hop, then Right Mastcam will image the target AEGIS selected yesterday and examine rocks named "Heald Mountain," "Caucomgomoc Lake," and "Mooselookmeguntic Lake."  Mastcam will also search for late-morning dust devils.  After the drill diagnostics and full suites of MAHLI images of The Hop and The Horns, the APXS will be placed on The Hop for an overnight integration.  Early the next morning, Navcam will search for clouds and Mastcam will measure the amount of dust in the atmosphere.
