After the devastating loss of two back-to-back missions to Mars in 1999, NASA’s Jet Propulsion Laboratory found itself at a crossroads. Would the lab pull back, becoming more cautious and conservative with the new missions it was willing to take on? Or would JPL, as one engineer put it, “get back in

Would the lab pull back, becoming more cautious and conservative with the new missions it was willing to take on? Or would, as one engineer put it, “get back in the saddle” and continue its tradition of pursuing challenging and innovative missions?
That question was answered when JPL proposed designing and building from scratch an entirely new type of Martian rover on an extremely tight schedule, and launching not one, but two of them to the Red Planet. The mission’s proposer thought he could rely upon the proven Entry, Descent and Landing system used by Mars Pathfinder, employing parachutes and airbags.
The Spirit Rover was a robotic spacecraft that was part of NASA’s Mars Exploration Rover mission. It was launched on June 10, 2003, and landed on Mars on January 4, 2004. The rover was designed to explore the Martian surface and carry out scientific experiments to study the planet’s geology, atmosphere, and search for evidence of past or present life.
The Opportunity Rover was a robotic spacecraft that was part of NASA’s Mars Exploration Rover mission. It was launched on July 7, 2003, and landed on Mars on January 25, 2004. The rover was designed to explore the Martian surface and carry out scientific experiments to study the planet’s geology, atmosphere, and search for evidence of past or present life.
