Unless they are coming up on their own, it takes about 2.5 hours to get down to the wreck, and what I've read online is that these subs carry like edit:12 hours of oxygen.Docs on the submarine show 96 hours of oxygen, this was wrong of me to guess
They need to get a towing vessel to the area, they need to get the rescue sub down to the bottom, winch up, and get back up. 6 hours of work once you're there. That means they have less than 4.5 hours to get on station. It's 1000 miles from Boston. Ain't no ship in the world sailing at under 200 knots.
Bad news only from this. They gotta get up on their own.
I've read a probable scenario about accidents with small DSVs in the book Below(Edit) the Edge of Darkness (about marine biology of bioluminescence and the tech developed by the author to film/record it):
There was a small leak in a valve, used for emergency operation IIRC and the author noticed that going down - she was still light enough to ascend but she said had she been a few hundred meters deeper, she never would have made it back up due to the extra weight.
What you're describing is similar to the leading theory for what happened to the USS Thresher. Flooding occurred and then when the sub went to emergency blow its ballast to surface, ice formed in the piping blocking the pressurized release of ballast water, causing the sub to sink uncontrollably. There's a good gif doing a better job explaining it on the wiki. Interestingly, the evidence used to determine this theory was gathered by Robert Ballard the famous oceanographer who then went on to be the first to find the remains of the Titanic. It all come full circle!
Eh, here's a question from the bbc article in question:
The vessel weighs 10,432 kg (23,000 lbs) and, according to the website, can reach depths of up to 4,000m and has 96 hours of life support available for a crew of five.
The issue is less the oxygen and more the carbon dioxide removal. assuming the sun has good scrubbers to clean out the co2 then okay, however it can depend how they are powered. There are comparisons to the Apollo 13 situation here.
Trapped in a sub amongst the wreckage of the Titanic is nightmare fuel. I don't think I would have even came up with that on my own, I thought they only send robotic subs down that far.
The US military literally uses Xbox controllers for a lot of their drones and tech.
It's kind of a rare move by the Pentagon of actually spend smartly.
Why spend millions on R&D to develop something that already exists and has been iterated based on massive operator feedback a dozen times over decades? It's literally a platform that has been designed and honed to operate vehicles of every shape and size.
I initially thought this post was about a reddit sub going missing, and I was very confused about why anyone would pay to be part of it, or why there would be a search.
I feel like a terrible human. I thought exactly the same, and had already scrolled on past. My short-term memory loop made me scroll back up a couple seconds later.
Would it make you feel any better if I told you that's probably not a threat for much longer? I'm not a scientist, but my understanding is that spot is probably at a gentle simmer by now.
Looks like a jurisdiction thing--a Canadian ship launched it though.
The submersible was reported missing after it was overdue by a couple of hours on Sunday evening, according to Chief Mi'sel Joe — head of the Mi'kmaq band which owns the ship from which the submersible is launched.
