Summary:
- Robots have been used to explore the surface of Mars and the Moon, allowing us to study these distant worlds without sending human astronauts.
- These walking robots, called rovers, are designed to navigate rough terrain and conduct scientific experiments on the surface of other planets.
- The Perseverance rover, which landed on Mars in 2021, is the latest example of this technology, and it is helping us learn more about the geology and potential for life on the Red Planet.
