Two high-resolution 3-D cameras that Hollywood director James Cameron was helping to build for NASA's next Mars rover have been abandoned by the space agency.
Nasa said work on the devices was halted because there wasn't enough time to thoroughly test them before launch.
Cameron, the Oscar-winning director of 3-D blockbuster Avatar, last year lobbied Nasa to revive a plan to give rover Curiosity a better set of eyes and worked with engineers to build them.
But project scientist John Grotzinger said Curiosity's current camera was powerful enough to meet mission goals.
