NASA Tests ERNEST Prototype Rover in California Desert
confidence 90%NASA's Jet Propulsion Laboratory is testing ERNEST, a four-wheeled prototype designed for extreme sloped terrain. The rover recently completed a 16-mile autonomous trek across the Colorado Desert. It is built to be faster and tougher than previous planetary explorers.
What's confirmed:
- ERNEST stands for Exploration Rover for Navigating Extreme Sloped Terrain.
- The rover is a four-wheeled prototype developed at NASA's Jet Propulsion Laboratory.
- During a March 2026 field test near Plaster City, California, the rover drove 16 miles autonomously.
- ERNEST is designed to travel at 10 times the speed of its predecessors.
- The rover serves as a test bed for autonomy software intended for potential lunar missions.
Still unconfirmed:
- The rover drove 16 miles in 37 hours.
- The rover can lift its wheels to climb obstacles.
- ERNEST is 10 times faster than Curiosity.
- ERNEST is 10 times faster than Perseverance.
