NASA to Send New Mars Rover in 2020

Maybe call it "Curiouser and Curiouser"?

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.
