Summary

Description	English: PIA16817: Major Volatiles Released from the Fourth 'John Klein' Portion http://photojournal.jpl.nasa.gov/catalog/PIA16817 Target Name: Mars Mission: Mars Science Laboratory (MSL) Spacecraft: Curiosity Instrument: SAM Product Size: 1242 x 782 pixels (width x height) Produced By: JPL Full-Res TIFF: PIA16817.tif (2.915 MB) Full-Res JPEG: PIA16817.jpg (134.4 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: As the Sample Analysis at Mars (SAM) suite of instruments on NASA's Curiosity Mars rover heats a sample, gases are released (or "evolved") from the sample and can be identified using SAM's quadrupole mass spectrometer. This graphic shows the principal gases evolved from the fourth portion of powder delivered to SAM from the sample material collected when Curiosity first drilled into the "John Klein" target rock in the "Yellowknife Bay" area of Mars' Gale Crater. The mass spectrometer signal is scaled separately for each gas so that the same graph can illustrate the patterns for various gases showing what temperatures caused the gas to be released. These evolved gases and the temperatures at which they evolved suggest the presence of hydrated minerals, carbonates, perchlorates, sulfates and sulfides, and clays in the rock-powder sample. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Mars Science Laboratory Project and the mission's Curiosity rover for NASA's Science Mission Directorate in Washington. The rover was designed and assembled at JPL, a division of the California Institute of Technology in Pasadena.
