English: PIA16705: Veins in 'Sheepbed' Outcrop
http://photojournal.jpl.nasa.gov/catalog/PIA16705 Target Name: Mars Is a satellite of: Sol (our sun) Mission: Mars Science Laboratory (MSL) Spacecraft: Curiosity Instrument: Mastcam Product Size: 1344 x 1200 pixels (width x height) Produced By: Malin Space Science Systems Full-Res TIFF: PIA16705.tif (4.84 MB) Full-Res JPEG: PIA16705.jpg (456.9 kB) Click on the image above to download a moderately sized image in JPEG format (possibly reduced in size from original) Original Caption Released with Image: Annotated Image Click on the image for larger version This image of an outcrop at the "Sheepbed" locality, taken by NASA's Curiosity Mars rover with its right Mast Camera (Mastcam), shows well-defined veins filled with whitish minerals, interpreted as calcium sulfate. These veins form when water circulates through fractures, depositing minerals along the sides of the fracture, to form a vein.These veins are Curiosity's first look at minerals that formed within water that percolated within a subsurface environment.These vein fills are characteristic of the stratigraphically lowest unit in the "Yellowknife Bay" area -- known as the Sheepbed Unit. Mastcam obtained these images the 126th Martian day, or sol, of Curiosity's mission on Mars (Dec. 13, 2012). The view covers an area about 16 inches (40 centimeters) across.A superimposed scale bar is 8 centimeters (3.15 inch) long. The image has been white-balanced to show what the rock would look like if it were on Earth. Polski: Zdjęcie wychodni w miejscu "Sheepbed", wykonała prawa kamera masztowa (MastCam) łazika Curiosity, pokazuje dobrze zdefiniowane żyły wypełnione białawymi minerałami, interpretowanymi jako siarczany wapnia.
Takie żyły tworzą się gdy woda krąży wzdłuż załamań osadzając minerały po obu stronach tych miejsc, tworząc żyłę. Te żyły, to pierwsze spojrzenie kamery łazika Curiosity na minerały, które powstały w wodzie na drodze perkolacji w środowisku podpowierzchniowym. Te żyły wypełnia charakterystyczna stratygraficznie najniższa jednostka w obszarze "Yellowknife Bay" - znana jako Sheepbed Unit. Kamera (Mastcam) wykonała zdjęcia w 126. dniu marsjańskim, lub Sol 126, misji łazika Curiosity na Marsie (13 grudnia 2012).Widok obejmuje obszar około 40 centymetrów w poprzek. Nałożony przymiar kreskowy ma 8 cm długościZdjęcie miało przeprowadzony balans bieli, aby pokazać skałę taką, jakby była na Ziemi.
