What did the Sojouner Rover do?

Answer 1

The Sojourner Rover, part of NASA's Mars Pathfinder mission, was the first successful robotic rover to operate on Mars, landing on the planet in July 1997. It conducted scientific experiments, analyzed soil and rock samples, and transmitted data back to Earth, contributing valuable insights into Martian geology and atmosphere. Sojourner traveled over 100 meters on the Martian surface, demonstrating the feasibility of mobile exploration on other planets. Its successful operation paved the way for future rover missions on Mars.
