No Mars mission for Cameron gadget
A high-resolution 3D camera that Avatar director James Cameron was helping to build for Nasa's next Mars rover will not fly after all.
Nasa said work on the zoom camera was halted because there was not enough time to thoroughly test it before launch.
Cameron last year lobbied Nasa to revive a plan to give rover Curiosity a better set of eyes and worked with engineers to build it.
Project scientist John Grotzinger said Curiosity's current camera is powerful enough to meet mission goals.
In a statement released by Nasa, Cameron said he is confident future missions will benefit from the work he and others invested even if Curiosity won't.
The Curiosity is scheduled to launch later this year and land on Mars in August 2012.
