Rovers are built to be tough and strong so they can handle rough ground and extreme temperatures. They have cameras to take pictures, arms to scoop up dirt, and special tools to test what rocks are made of. They send all their information back to scientists on Earth using radio signals. Scientists on Earth tell the rover where to drive next!
- Some rovers run on solar power from the Sun, and others use a special battery that lasts for years.
- Rovers have explored Mars and the Moon.
- The Opportunity rover on Mars was only supposed to work for 90 days but kept going for about 15 years!
