NASA Tests Extreme Terrain Rover for Mars & Moon
21 Jun
Summary
- Ernest prototype navigates extreme slopes and obstacles.
- It boasts advanced active suspension for greater mobility.
- The rover achieved a top speed of 0.6 mph in recent tests.

NASA has unveiled its Ernest prototype rover, designed to tackle the extreme terrains of Mars and the Moon. Current Mars rovers are slow and struggle with obstacles, but Ernest features a unique design with four independently steerable wheels and an advanced active suspension system.
This system allows Ernest to articulate its wheels, enabling it to climb over rocks and traverse steep slopes that would challenge existing rovers. During recent seven-day trials in the Colorado Desert, the prototype covered approximately 16 miles, achieving a top speed of 0.6 mph. Engineers are exploring various active suspension configurations to enhance mobility.
The Ernest prototype represents a significant leap towards future exploration vehicles. Its enhanced independent decision-making capabilities aim to reduce reliance on human controllers, paving the way for faster and more extensive missions across extraterrestrial surfaces. The technology is being developed for potential use on both lunar and Martian exploration missions.
