MUMBAI: James Cameron is soon to dive to the deepest
place on Earth in a one-man submarine. His vessel, named
the Deepsea Challenger, will carry him 11km down to
the bottom of the Mariana Trench in the western Pacific.
director will spend his nine-hour dive in a thick, metal
sphere with an internal diameter of just 109cm (43in)
where he will be unable to stretch his arms or legs.
The rest of the sub is made from specially designed
syntactic foam, similar to the material from which a
surf board is made. It counterbalances the weight of
the pilot's compartment, which will have to protect
Cameron from 1,000 atmospheres of pressure.
Cameron attempts the Mariana dive, a science team headed
up by Doug Bartlett from the Scripps Institute will
be dropping a lander fitted with 3D cameras and baited
to attract any passing life.
Walsh, who made the first and the only manned mission
to the Mariana Trench with Swiss oceanographer Jacques
Piccard in 1960, has joined the team. Once they can
get a few days of good weather, the team hopes to first
make an unmanned 11km dive with the sub to check that
it works properly and then send Cameron down.
and his team had earlier performed a similar feat; taking
a successful 8,200m test-dive in Papua New Guinea.
