The US space agency (NASA) says it will launch a new rover to Mars in 2020.
The vehicle will be based on its Curiosity robot, which landed on the Red Planet in August.
Nasa expects to re-use many of the technologies that worked so successfully in getting the one-tonne spacecraft down into the huge equatorial bowl known as Gale Crater.
This included a rocket-powered crane that lowered Curiosity to the surface on nylon cords.
