spacecraft and submarines is that many issues are almost identical. for example on life support you have to add oxygen, scrub out the co2, manage the total pressure, you want to keep the temperature within livable range. that sort of thing. then when you get to the pressures involved the two types of vehicles deviate dramatically. in the case of a spacecraft you re only having to hold in one atmospheric pressure compared to the vacuum of space. when you are going down, down to the mariana trench it is a thousand atmospheres of pressure. here at the titanic it is merely about 500 times the surface pressure of air. which is still obviously an enormous amount of pressure and that is why a spaceship hull is very thin, not much more than a coke can, but it takes numerous inches of steel or in this case carbon fiber to hold out the enormous pressure. plus the design is, you know, a spacecraft has often a more complex shape.
you have to appreciate that this submersible is capable of going to 380 atmospheres of depth, and you re talking at a million and a half pounds of pressure on the ship. let s break that down. you re about 5,600 pounds for square inch on the outer hull of this vehicle. just the breathing medium, and effects, physiological and psychological, the nervous system syndrome, and all these thing. the occupants are not at that kind of pressure, the inner hull has to keep them it s hyperbaric technology. however, we re talking, what, 40 hours remaining? that s a long time to be at that depth. so the coast guard is saying they re breathing in compression chambers, hyperbaric chambers, because once you get these
vesselses that are on their way to the site, some we hope and we believe with the kind of deep water assets that could potentially find the missing submersible if it is indeed on the seabed and make the recovery. if they do locate the submersible before the estimated oxygen levels run out, what might the rescue effort look like? is it possible to pull the vessel that could be about 13,000 feet deep in the ocean back to the surface, and how slowly would they need to do it so they don t cause any harm as the individuals go up several atmospheres? this is one atmospheric sub, so we don t really have to worry about the pressure that people suffer when they are scuba diving for instance. they can come out to the surface and walk out of that submarine without any ill effects. if it is a bit of a rough ride to the surface, so be it as long as they are safe. but you have to remember while this submarine is very big and
planets and the james webb telescopes can see into the atmospheres that are ten light years away, and that s how we ll answer this question because there s nothing i can do when someone tells me a story i can t tell if someone is lying and this amazing method calls science, and the cell phones we turn to every time there s ais kro crisis, and it s a way to be in dialogue with the world and if we want to know about the universe, that s the only way to answer the questions. if folks in las vegas and their instinct doesn t say it s a meteor, i mean, who are you going to call? call the police. call dog pound. call the very large dog pound. [ laughter ] i mean, i don t know. i don t know, but it s not take pictures, but always what youio see is always fuzzy mblob.
