i like the story about how it was found. The search was cover for a secret military operation, and they kinda actually found it by mistake after the mission:<a href="https:&#x2F;&#x2F;spyscape.com&#x2F;article&#x2F;how-the-titanic-was-discovered-during-a-secret-cold-war-navy-mission#" rel="nofollow">https:&#x2F;&#x2F;spyscape.com&#x2F;article&#x2F;how-the-titanic-was-discovered-...</a>

The Titanic is on a perpetual news cycle. How every decade it somehow manages to make news is interesting.

Since there are already submersibles and cameras that work at that depth, that cuts down the size of the problem space quite a bit.

I think you&#x27;ll find this youtube channel very interesting: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;@CPSdrone" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;@CPSdrone</a>

&gt; exploring an environment with unknown shapes, dangerous sharp edges,We know the original blueprints. We can program that into a robot, along with existing known differences. Then the robot needs to just detect anything that isn&#x27;t like expected and photograph it and return. After a few rounds of that you would get most of the interesting areas explored.Currents are handled just by comparing expected return signals to what you really see.OF course worth it is questionable.The above fails in the general case only because generally in navigation we also have safety considerations. Your self driving car cannot run over a child no matter what. However there is much less to worry about in the Titanic. (don&#x27;t confuse that with this is easy, only that if you don&#x27;t worry about safety it is much easier)

Undersea drones are a remarkably (and fascinatingly!) complex field.Ignoring all the mechanical challenges (airtight, watertight machine that can operate under crushing pressures and still has a way to separate delicate, saltwater-sensitive electronics and actuators from external-facing motive devices), the communications are also a challenge: radio does awful under water (VLF can go 100 feet, but now you&#x27;re trying to control something inside the Titanic with radio signals that bounce off all the still-existent metal in wild ways; problem is a bit harder than &quot;get full WiFi coverage of your house&quot;). Sound would actually probably be a great tool, but sound also behaves strangely under water that deep. The most well-researched, well-tested solution is a long cable back to the control ship, but that constrains how deep you can get into the Titanic (one idea I&#x27;ve never seen floated: attach a fleet of robots to the cable, a main one for exploration and observation and multiple wire-managers who&#x27;s full job is to anchor to something and manage the cable slack... But now you&#x27;re anchoring to the wreck, so that&#x27;s also not good).Fully-autonomous robots might actually be the best option here, and the only thing stopping that is the actual research and development to build a machine that can make independent decisions exploring an environment with unknown shapes, dangerous sharp edges, and possible currents, in full 3D. We&#x27;ve put more research into rovers on Mars than into this problem.

Anything you&#x27;re remotely sending down there is going to be attached to a long wire and rather big. Also navigating tight spaces underwater can be challenging even for a human, in person. Navigating them with a brick remotely is much harder.Some setups have smaller ROVs launched from another submersible, like ROV ROBIN.

One does wonder precisely how many decades (or centuries) have to pass before &quot;desecrating a mass grave&quot; becomes &quot;archaeology&quot; (... &quot;he ruminates while thinking about that fascinating Pompeii exhibit that toured through town one year...&quot;).

&gt; * Extremely niche technology that would have few practical uses in other contexts since most of the seabed does not suffer from the same complexities as a shipwreckThis is why the wreck of the Titanic got found in the first place though <a href="https:&#x2F;&#x2F;www.nationalgeographic.com&#x2F;premium&#x2F;article&#x2F;titanic-was-found-during-secret-cold-war-navy-mission" rel="nofollow">https:&#x2F;&#x2F;www.nationalgeographic.com&#x2F;premium&#x2F;article&#x2F;titanic-w...</a> (<a href="https:&#x2F;&#x2F;archive.is&#x2F;jibqF" rel="nofollow">https:&#x2F;&#x2F;archive.is&#x2F;jibqF</a>)

&gt; desecrating a mass grave under maritime lawThat never made sense to me. Massive efforts are made to retrieve bodies from airplane crashes, sunk boats, collapsed buildings, etc. Why is recovery from some other disaster sites &quot;desecration&quot;?

One of those rare occasions where I can&#x27;t possibly just salute an excellent comment with a mere upvote. Superbly balanced effort, each bullet point equally devastating and perfectly expressed.

Take your pick:* Difficult to navigate in a narrow underwater structure without crashing* Signal penetration, or lack thereof, in an iron hull at the bottom of the Atlantic Ocean* Extremely niche technology that would have few practical uses in other contexts since most of the seabed does not suffer from the same complexities as a shipwreck* Can&#x27;t see for shit underwater in general* We already know whats down there and why it&#x27;s down there, therefore unlikely to lead to significant new information* This could actually be considered desecrating a mass grave under maritime law

s&#x2F;why there aren&#x27;t&#x2F;whether there are<a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=pun18bi_0-g" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=pun18bi_0-g</a>

I&#x27;m curious why there aren&#x27;t drone cameras that can explore the interior.

&gt; engineers worked right to the end to keep the ship&#x27;s lights onCuriously, this reminded me of engineers who are working to make AI better which will one day take their own jobs.
