Re: Shooting in 3D of absolutely nothing and collecting no samples.
It's not like me to defend Cameron, but having read that they are planning more trips down there, I think it's fair to say that the trip was a success. The mechanical failure that prevented sample collection can surely be fixed, and if future trips do manage to bring back samples, that will add to the project's success. In the meantime, the project is a success for having shown that the submersible worked almost perfectly. That's my take on it, anyway.
