After trying its luck as a hip-hop broadcaster to other planets, #NASA now appears to have gone down the "AI" road, calling repeatedly "AI" what the article reveals is an “adaptive sampling” technique used by #Perseverance with its #PIXL instrument.

The article seems to be calling "AI" everything that's done automatically on the rover, even its AutoNav system, which last time I checked was still called AutoNav.

Here’s How AI Is Changing NASA’s Mars Rover Science

Artificial intelligence is helping scientists to identify minerals within rocks studied by the Perseverance rover.

Here is a sample lab-generated X-ray spectra for the NIST 610 glass standard, which is used for one of the 4 disks in the PIXL calibration disk.
The monthly scan of the calibration disk by PIXL must compare results with similar graphs to measure, and perhaps to correct, any deviations in PIXL's measurements.

The PIXL instrument can detect elements: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Br, Rb, Sr, Y, Ga, Ge, As, and Zr, with important trace elements such as Rb, Sr, Y and Zr detectable at 10’s ppm level.

PIXL for Scientists - NASA

PIXL For Scientists

The PIXL Sensor Assembly is mounted at the end of the rover’s robotic arm. The control electronics are mounted inside the rover body.

The PIXL calibration target is mounted at the base of the robotic arm, on the front side of the rover.

The graphic below shows the location of PIXL and its calibration target, with PIXL looking directly at the calibration target.

PIXL (Planetary Instrument for X-Ray Lithochemistry)

Get help for the Analyst's Notebook, a web application that integrates sequence information, engineering and science data, and documentation from NASA's landed missions on Mars and Earth's Moon.

PIXL measures the fine-scale chemical makeup of rocks using an X-ray spectrometer and a camera. It focuses an X-ray beam to a small spot ~ 150 µm, scans the surface with this beam, and then measures the induced X-ray fluorescence.

The presence of different elements result in spikes at various wavelengths and energy levels, which are measured by PIXL's X-ray spectrometer.

What is that curious looking object imaged by Mars Rover Perseverance yesterday?
No, it is not a target practice plate for SHERLOC the laser zapper, it is the calibration target for PIXL, the Planetary Instrument for X-Ray Lithochemistry, which is mounted at the end of the robotic arm along with SHERLOC and the drilling apparatus.
The calibration target contains 4 sample disks with known X-ray signatures that PIXL scans approx. once a month.
