> NASA JPL (Jan 30) detailed the first AI-planned Mars rover drives: Anthropic’s Claude helped plot Perseverance routes executed Dec 8 and 10, 2025 in Jezero (~400m-class rocky terrain). Engineers validated waypoints in simulation before uplink—generative AI in science ops, not onboard autonomy alone.

Planetary ops are high-stakes workflows: scarce airtime, multi-million-dollar hardware, irreversible mistakes. The proprietary frame: Claude contributed to **ground planning**—with human-in-the-loop validation—not a story about an unsupervised rover LLM on Mars.

**NASA JPL** on January 30 announced that **Perseverance** completed the **first AI-planned drives on another world**, using **Anthropic’s Claude** to help generate navigation plans for drives on **December 8 and 10, 2025** in **Jezero Crater**. Claude assisted with ~**400-meter-class** routing through rocky/boulder and ripple terrain (some coverage cites ~456 m combined context). Process: Claude analyzed imagery/terrain data to propose waypoints; **JPL engineers validated** outputs in operational simulations before commands were uplinked. Impact claim: engineers reported substantial route-planning time savings (Anthropic: on the order of **half** in engineer estimates). Framing: ground LLM/VLM planning stack—not a replacement for onboard autonomy systems alone.

## Claims vs checks

Achievement framing, dates, and human-validation process are **NASA JPL primary** plus Anthropic’s “Claude on Mars” feature. Distance figures and “half the time” estimates are engineer/company-reported—not a controlled time-motion study published here. Engadget and science/tech wires same-day.

## Limits

- Ground planning ≠ onboard closed-loop LLM driving.
- Two December drives are a landmark case, not a new default ops mode for all sols.
- Time-savings percentages are estimates.
