# NASA JPL: Perseverance Enhanced Autonomous Navigation

Communication latency requires local path authority.

Function: Engineering design. Patterns: Creator to judge. Evidence: verified.

Freshness: current. Reviewed: 2026-08-23. Updated: 2026-08-22.


Source quality: 1 peer reviewed, 1 primary; publication outcomes are verified.

## Before

1. **Earth rover planners** — Use orbital and rover imagery to define route goals and commanded drive segments. (control: Communication delay prevents real-time joystick control; prior rover comparison provides no uniform terrain-adjusted cycle time.)
2. **Rover and ground team** — Executes a commanded segment and waits for telemetry review before subsequent planning. (control: Ground mission safety review.)

## After

1. **Enhanced AutoNav** — Builds local terrain maps, checks collision/slip risk, and selects paths onboard. (control: Conservative wheel bounding boxes, FPGA vision, and stop behavior.)
2. **Earth operations team** — Sets goals and corridors, reviews telemetry, and handles hazards that stop autonomous progress. (control: Human mission authority; ENav owns only bounded local motion.)

## Decision rights

ENav owns local motion; Earth owns mission goals.

## Exception path

Hazard or uncertainty stops rover for ground review.

## Outcomes

- **Autonomous distance share** (verified): Earlier rovers at most 5% in cited comparison → About 90% of 32.1 km used ENav. Cross-generation mission comparison.

## Executive lesson

Humans specify intent; the machine owns safe local action.

## Anti-pattern

Do not compare speed without terrain context.

## Questions for leaders

- Where is the operating threshold set and who can override it?
- What measured result would trigger rollback or retraining?
- Which residual decisions must remain human-owned?
