Planetary Instrument for X-Ray Lithochemistry

Planetary Instrument for X-Ray Lithochemistry (PIXL) is an X-ray fluorescence spectrometer to determine the fine scale elemental composition of Martian surface materials designed for the Perseverance rover as part of the Mars 2020 mission.

[1][2] PIXL is manufactured and made by NASA Jet Propulsion Laboratory.

The scientific objectives of the instrument are the following:[3]

Mars Perseverance rover - PIXL studies a rock (artist concept)
Perseverance rover - PIXL (31 July 2014).
PIXL − first chemical maps of a single rock on Mars (20 July 2021)
PIXL imaged on Mars by the rover's navigation camera.
