Who made the mars rover opportunity?

The Mars rover Opportunity was developed by NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. It was part of the Mars Exploration Rover mission, which was designed to explore the Martian surface and search for signs of past water. Opportunity was built by a team led by Steve Squyres, who oversaw the scientific objectives and operations of the rover. Launched in 2003, Opportunity operated for nearly 15 years, far exceeding its original mission duration.
