Appearance

Mars Perseverance rover - PIXL studies a rock (artist concept)
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.
Science objectives
[edit]The scientific objectives of the instrument are the following:[3]
- Provide detailed geochemical assessment of past environments, habitability, and biosignature preservation potential.
- Detect any potential chemical biosignatures that are encountered and characterize the geochemistry of any other types of potential biosignatures detected.
- Provide a detailed geochemical basis for selection of a compelling set of samples for return to Earth.
