It was pretty cool to hear that James Cameron got NASA to put 3D cameras in Curiosity, the next Mars Rover. If 3D is good for anything, it’s exploring space and worlds we’ve never actually seen before (see: Avatar). But alas, NASA decided against it.
Why? Basically, NASA didn’t have enough time to go through all the testing of the camera before launch. Makes some sense, you wouldn’t want a faulty cam when you’re on holidays let alone Mars. According to NASA:
The possibility for a zoom-camera upgrade was very much worth pursuing, but time became too short for the levels of testing that would be needed for them to confidently replace the existing cameras.”
