The robotic Sojourner rover reached Mars on July 4, 1997 as part of the Mars Pathfinder mission. Sojourner was operational on Mars for 92 sols (95 Earth days), and was the first wheeled vehicle to operate on an astronomical object other than the Earth or Moon.
The rover made measurements of the elements found in those rocks and in the martian soil, while the lander took pictures of the Sojourner and the surrounding terrain, in addition to making climate observations. The Sojourner is a six-wheeled, 65 cm (26 in) long vehicle, 48 cm (19 in) wide, 30 cm (12 in) tall and weighing 10.5 kg (23 lb). [27]

NASA's Curiosity rover, selfie, 2015. A Mars rover is a remote-controlled motor vehicle designed to travel on the surface of Mars. Rovers have several advantages over stationary landers: they examine more territory, they can be directed to interesting features, they can place themselves in sunny positions to weather winter months, and they can advance the knowledge of how to perform very ...
Director Ryan White shares his thoughts on his new documentary, "Good Night Oppy," the real-life fable of a Mars robot that refused to die and the dedicated NASA team that kept it going.
On the way, Curiosity studied a pyramidal rock dubbed "Jake Matijevic" after a mathematician-turned-rover-engineer who played a critical role in the design of the six-wheeled rover, but died just days after Curiosity landed in August. [60] The Jake rock measures about 25 cm (9.8 in) tall and 40 cm (16 in) wide. [61]
