And for what it’s worth, the only personal experience I have with carbon fiber is a paintball tank. (I actually played for Rutgers Paintball team 2008-2010). Those tanks are very small but have 4500psi of pressure contained in them. And they’re filled and used and refilled again A LOT. Those are required to be tested every 10 years and are often connected to a steel valve. Carbon fiber in that fashion is extremely strong, but that’s considering the fact that it’s internal pressure pushing outward. So maybe it’s just a poor choice of materials? Again, this is just my common sense knowledge.
cf is great with tightening conditions and impulses but not compression as the thread degrade.

great for gun barrels and a host of mil applications but as a wrap glued to a hull no that's a hell no

no they wouldn't, barely even notice a bubble or two

you guys watch too many movies
Ok wasn’t sure. Just thought something imploding would have to create quite a disturbance being that the Navy may have heard it at god knows how far away.

People really think the Navy is going to have to ask congress for additional funding to pay this magical bill 😂
Actually yes. Maybe not for the ‘bill’ but for never ending technology advances in this space. Public and privates all beg for more every year. It’s how budgets work.

I think they are equally interesting.

Humanity needs to progress with space travel because, at some point, there are going to be too many people on the planet and we will overwhelm the required resources. And because sooner or later, a killer bacteria or virus will wipe us all out so it would be nice if we have people living somewhere else to continue the species.

But the oceans may also hold promise for helping solve certain issues in the meantime.
Would it be any harder to establish underwater communities than communities on Mars? Either place you need a source of oxygen.

If you have a power source you can make oxygen from water. That's what all the nuclear subs do.

On Mars, not so much.

I've done a little diving, but not since my best friend was killed in a diving accident on U-352 off the coast of North Carolina about 20 years ago.

Both are unforgiving environments. But space is far more unforgiving, far less recoverable.


Damn straight

Texas Tower, my gauge said 178 but its' listed to 185 or so, was a hoot! I've not been back since it's sunk further and collapsed. I used to do a lot of diving

you do feel the pressure on the body for sure
Wow, i'm impressed - I believe your gauge.

Anyone ever read " Shadow Divers" by Robert Kurson?

This might be my favorite book - EVER!

I agree with him that carbon fiber is not the correct material for a vessel exposed to compressive forces.

That said, I AM NOT going to base any life and death decisions based on what James Cameron says. There are far better qualified folks to ask these questions.
But but but….

His name is JAMES CAMERON,
The Bravest Pioneer!
No budget to steep,
No sea too deep,
Who’s that? It’s him!
James Cam-er-on!

JAMES CAMERON,
Explorer of the sea!
With a dying thirst,
To be the first,
Could it be? It’s him!
James Cam-er-on…..

anyone see the pics of the joystick on the ocean floor? Cap is intact from pics so looks like hull issue and not that front glass. Also they releases weight so in all probability, they knew something was wrong and tried to ascend but couldn't and then imploded. Thankfully, it's so fast they never knew it happened.

'J. Cameron tells CNN that his sources told him the Titan jettisoned its ballast before the implosion. He says the crew must have observed the delamination of the hull and attempted an urgent recovery'

RIP

I think the supposition is correct based on the owner saying he made his hiring decisions based on DEI nonsense. You don't need to be Sherlock Holmes to solve this one.
We should expect a lot more of this. The prevailing culture is now firmly on a trajectory opposite of a merit or colorblind society. Everyone is labeled and some labels are better than others.

Never had interest in going that deep. I applaud the work and courage it took to do that. You don't just jump into that.

What is the bottom time @ 180? Can't be long even with mixed gas. How many stops on the way up?

Yes, this another example of carbon fiber composites used under tension. These tanks also have an aluminum bladder so theyre not completely reliant on the composite. I thought these needed to be tested every 5 yrs with max lifetime of 15yr. These were designed with a large safety margin and are a certified design. I would still use these with caution. I think the biggest risk would be surface impact damage to the carbon fiber which would compromise the integrity. I wouldn't want to be near one that failed. The number of fill cycles I think should dictate lifetime rather than time.
