July 4th 1997
The Mars Pathfinder Lander was launched from the Kennedy Space Center on the 4th of December 1996. After a 7 month voyage, it landed in a region called Chryse planitia on the 4th of July 1997 (Independence day!). Inside the lander was the rover Sojourner, which took 550 images (the lander took 16 500) before transmissions was lost on the 27th of September 1997.
The Mars Rover was not discovered it was invented.
The Mars rover Opprutunity landed on January 24, 2004 By Aj
Eight rovers were sent to Mars: Mars 2, Prop-M rover, 1971, failed Mars 3, Prop-M rover, 1971, failed Viking 1, landed July 20, 1976, longest rover to function on Mars (6 years 116 days), lost contact due to a faulty command on November 11, 1982. Viking 2, landed September 3, 1976, stopped functioning on 11 April 1980 when its batteries stopped working Sojourner rover, Mars Pathfinder, landed successfully on July 4, 1997. Communications were lost on September 27, 1997. Spirit, Mars Exploration Rover, landed successfully on January 4, 2004. Rover is still operating as of April 3, 2009, 5 years after the original mission limit. Opportunity, Mars Exploration Rover, landed successfully on January 25, 2004. Rover is still operating as of April 3, 2009, 5 years after the original mission limit. Phoenix, landed May 25, 2008, confirmed presence of water-ice on Mars, mission ended November 10, 2008. These Mars rovers are in development: Mars Science Laboratory, by NASA. Planned Mars launch 2011. ExoMars, by the ESA. Planned Mars launch 2016.

The Mars rover Perseverance was launched on July 30, 2020, and landed on Mars on February 18, 2021.
The concept of a rover, specifically for space exploration, began with the development of the Soviet Union's Lunokhod 1, which was launched in 1970. However, the term "rover" can also refer to various types of robotic vehicles used in different contexts, so the invention date may vary depending on the specific application. In the context of Mars exploration, NASA's Sojourner rover was the first successful Mars rover, landing on the planet in 1997.

NASA's twin robot geologists, the Mars Exploration Rovers, launched toward Mars on June 10 and July 7, 2003, to find answers to the questions about water on Mars. They landed on Mars January 3 and January 24 PST, 2004.
Sojourner landed in July 1997 and communications were lost in September of that year. Spirit landed in January 2004, and is still functioning but it is stuck in sand. But data is still collected from it. Opportunity also landed in January 2004 and it still functional.
The first one was a pathfinder named Sojourner. The second and third were named phoenix and phoenix 2. The 4th was a rover called Opportunity which was followed by Spirit which landed in Gusev Crater that's believed to have been an ancient lake. The last one and
