Kurt, thanks for that info. Here's a link to the video of the Nereus picking up samples way down there: http://www.youtube.com/watch?v=9EMyymnC93E

Independent vehicles can descend to the depths of the Mariana Trench, but it is a more difficult engineering solution for ROV's.  Woods Hole Oceanographic sent a hydrid vehicle (can operate completely independent or with a fiber optic cable for communication) to the bottom of the trench a few years ago - the Nereus. 

Sending a manned vehicle down to that depth is a huge engineering feat and shows the determination to design and build a vehicle that can withstand the environment and sustain human life at the same time.

ROV's have a limitation with the power cable that controls their maneuvering, the length of the cable (over 8,000 meters) becomes an excessive force on the winch assembly.  At times the weight of the cable can be more than it's rated load, without the vehicle at the bitter end.

Glenn, ROVs are not usually engineered to dive anywhere near this deep--7 miles--because of the incredible pressure. From what I've seen, most of them can descend a few thousand meters.

Beth, I agree about Cameron--this impressed me as much as his work in Avatar.

Could an ROV have done the same exploration ?  Deep sea exploration, while very expensive, is still not as costly as space exploration.  There are some deep-diving submarines available to wealthy and determined persons.  Will Sir Richard Branson eventually branch out from Space Ship 2 to deep sea 'flights' ?

It's amazing the range of James Cameron's interests and skills. Not only is he a brilliant film director, but he's really been a pioneer of science, technology, and engineering, particularly as it relates to ocean expedition. There's so much to be gained from this work, and the lessons around engineering will find their way into numerous industries and applications--of that, I have no doubt.

Latest Analysis
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
US factory orders for durable goods tumbled 3.4% in December on a big drop in new bookings for commercial aircraft, according to data the Commerce Department released Tuesday.
