Which device is typically referred to as a "rover" in space exploration?

In space exploration, a "rover" specifically refers to a robot equipped with wheels that is designed to traverse the surface of other celestial bodies, such as planets or moons. These robotic vehicles are deployed to conduct scientific research and gather data in environments that are often inhospitable to humans. Rovers are typically equipped with various instruments for analyzing soil, taking images, and measuring atmospheric conditions, enabling scientists to learn more about the geological and potentially biological characteristics of other worlds.

The characteristics that define a rover are its mobility on the ground and its ability to perform tasks autonomously or remotely controlled. This capability allows rovers to explore areas that are difficult for landers to access and to operate for extended periods, providing valuable insights into the terrain and conditions of extraterrestrial landscapes.
