Curiosity's and Perseverance's Wheels

An image of the aluminum wheels of NASA's Curiosity (left) and Perseverance rovers.

April 03, 2020

Illustrated here, the aluminum wheels of NASA's Curiosity (left) and Perseverance rovers. Slightly larger in diameter and narrower, 20.7 inches (52.6 centimeters) versus 20 inches (50.8 centimeters), Perseverance's wheels have twice as many treads, and are gently curved instead of chevron-patterned.
