SOL0054-PIA14762-NASA-JPL-Caltech-MSSS.jpg"Bathurst Inlet" Rock - Sol 54 (Natural Colors; credts: NASA/JPL-Caltech, Malin Space Science Systems)86 visiteNASA's Mars Rover Curiosity held its Mars Hand Lens Imager (MAHLI) camera about 10,5" (---> inches, such as about 27 centimeters) away from the top of a Rock called "Bathurst Inlet" for a set of 8 images combined into this merged-focus view of the Rock. This context image covers an area that is roughly 6,5 by 5" (such as 16 by 12 centimeters). Resolution is about 105 microns per pixel.
MAHLI took the component images for this merged-focus view, plus closer-up images of Bathurst Inlet, during Curiosity's 54th Martian Day, or Sol (such as September 30, 2012). The instrument's principal investigator had invited Curiosity's science team to "MAHLI it up!" in the selection of Sol 54 targets for inspection with MAHLI and with the other instrument at the end of Curiosity's Arm: the Alpha Particle X-Ray Spectrometer.
The "Bathurst Inlet" Rock is dark gray and appears to be so fine-grained that MAHLI cannot resolve Grains or Crystals in it. This means that the Grains or Crystals, if there are any at all, are smaller than about 80 microns in size. Some windblown sand-sized Grains or Dust Aggregates have accumulated on the Surface of the Rock, but this Surface is clean (if compared, for example, to the pebbly substrate below the rock - upper left and lower right in this context image).
MAHLI can do focus merging onboard the MER and, in fact, the full-frame versions of the 8 separate images that were combined into this view were not even returned to Earth -- just the thumbnail versions. In other words, merging the images onboard reduces the volume of data that is supposed to be downlinked to Earth.MareKromium

ZZ-Mercury-Craters-Raffaello_Crater-PIA16307-PCF-LXTT-IPF-1.jpgRaffaello Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)86 visiteThis beautiful Absolute Natural Color image-mosaic of the huge Impact Basin Raffaello (named after the Italian Renaissance painter and having a diameter of approx. 343 Km), taken in the past month of October 2012 by the NASA - MESSENGER Spacecraft, shows us a wide diversity of colors (which, as you know, represent a wide variety of Mineral Compositions) that exist and can be easily identified within the Volcanic Plains that, eons ago, flooded the Raffaello Basin's Floor. Furthermore, many white-colored Hollows appear to be in process of being formed along most of the Rim and the Northern portion of the Floor - and, in both cases, they are forming in the so-called Low Reflectance Material (or LRM for short) - of a smaller - roughly 40-Kilometer (such as approx. 25-miles) diameter -, Unnamed and Highly Complex Impact Crater that is located just South of the center of the giant Raffaello Basin.

This picture (which is an Original NASA - MESSENGER Spacecraft color frame published on the NASA - Planetary Photojournal with the ID n. PIA 16307) has been additionally processed and then re-colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - MESSENGER Spacecraft and then looked down, towards the Surface of Mercury), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. Different colors, as well as different shades of the same color, mean, among other things, the existence of different Elements (Minerals) present on the Surface of Mercury, each having a different Albedo (---> Reflectivity) and Chemical Composition.MareKromium

SOL0139-PIA16706-PCF-LXTT-IPF.jpgSpherules at Gale Crater - Sol 139 (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)86 visiteCaption NASA:"This image from the Right Mast Camera (MastCam) onboard the NASA - Curiosity Mars Exploration Rover shows roughly Spherical Features, which are VERY similar to the ones found by the Mars Exploration Rover Opportunity in the Meridiani Planum Region of Mars. These "Gale Crater's" Spherules are apparently common in this Stratigraphic Unit, informally "Sheepbed"; a Stratigraphic Unit which defines the lower part of the sequences of Strata exposed in the area known as "Yellowknife Bay". These Spherical Features have been interpreted as "Concretions": a definition which implies that they have formed in Water that percolated (---> the movement and filtering of fluids through porous materials) through the Sediment. Curiosity's MastCam obtained these images on the 139th Martian day, or Sol, of the Rover's Surface Operations at Gale Crater (such as December, 25th, 2012)". 11 commentiMareKromium
