Adaptive sampling on Perseverance's PIXL instrument
Read the instrument's scans of a rock as they came in and decided, on Mars, where to look longer.

What was said, and by whom
-
“For almost three years, the rover mission has been testing a form of artificial intelligence that seeks out minerals in the Red Planet's rocks.”

“This marks the first time AI has been used on Mars to make autonomous decisions based on real-time analysis of rock composition.”

“the software autonomously positions the instrument close to a rock target, then looks at PIXL's scans of the target to find minerals worth examining more deeply”

Claims to a first
- First AI on Mars to decide from the composition of a rock: stands as worded. Scoped to decisions made from real-time analysis of rock composition. AEGIS chose targets on Mars from camera images from 2010, which is earlier and is a different thing.
Notes
Graded U, not R, because the release reports use over years. No launch mark is given: the claim is about software on a rover already on Mars.
