This diagram depicts the sensor head of the Planetary Instrument for X-RAY Lithochemistry, or PIXL, which has been selected as one of seven investigations for the payload of NASA's Mars 2020 rover mission. PIXL is an X-ray fluorescence spectrometer that will also contain an imager with high resolution to determine the fine-scale elemental composition of Martian surface materials.

Mars 2020 is a mission concept that NASA announced in late 2012 to re-use the basic engineering of Mars Science Laboratory to send a different rover to Mars, with new objectives and instruments, launching in 2020.

NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages NASA's Mars Exploration Program for the NASA Science Mission Directorate, Washington.
