Sub Sphere: What Protects Human Deep Divers? | National Geographic

if you want to venture to the bottom of
the world 36,000 feet beneath the sea
you don’t have a lot of options you need
the perfect shape made of strong heavy
material a steel sphere this epic dive
has been done only once before by the
Trieste expedition in 1960 then and now
this simple structure is the only way to
go for getting human beings to the
bottom we’re constrained by the amount
of pressure to a very small sphere in
order to just have the vehicle light
enough that we can even get it into the
water and back on a back on a ship on
the Trieste trip that meant the two-man
crew had to operate in a working space
smaller than a phone booth
Cameron’s journey won’t be any more
comfortable this is the steel sphere is
where the pilot holograms the space is
tiny Cameron will barely be able to move
for over nine hours as he pilots the
craft to the bottom and back he actually
took up yoga to help get more limber a
sphere is still the safest place to be
at the bottom of the ocean the design
hasn’t changed much since 1960 the
technology of the craft that gets it
down there is a very different story
the Trieste voyage was groundbreaking
but the craft itself was limited it took
so long to get down the crew could only
stay on the bottom for about 20 minutes
Kameron sub is state-of-the-art its
vertical orientation allows for a much
faster descent he’ll be able to explore
the bottom for over six hours filming
and collecting samples of this unknown
environment like never before
