James Cameron (Avatar's creator) Completes Record-Breaking Mariana Trench Dive
At noon on Monday, local time, (10 p.m. Sunday ET) James Cameron's "vertical torpedo" sub broke the surface of the western Pacific, carrying the National Geographic explorer and filmmaker back from the Mariana Trench's Challenger Deep—Earth's deepest, and perhaps most alien, realm.
The first human to reach the 6.8-mile-deep (11-kilometer-deep) undersea valley solo, Cameron arrived at the bottom with the tech to collect scientific data, specimens, and visions unthinkable in 1960, when the only other manned Challenger Deep dive took place, according to members of the National Geographic expedition.
After a faster-than-expected, roughly 70-minute ascent, Cameron's sub, bobbing in the open ocean, was spotted by helicopter and would soon be plucked from the Pacific by a research ship's crane. Earlier, the descent to Challenger Deep had taken 2 hours and 36 minutes.
Expedition member Kevin Hand called the timing of the DEEPSEA CHALLENGER sub's ascent "perfect."
"Jim came up in what must have been the best weather conditions we've seen, and it looks like there’s a squall on the horizon," said Hand, a NASA astrobiologist and National Geographic emerging explorer.
Before surfacing about 300 miles (500 kilometers) southwest of Guam, Cameron spent hours hovering over Challenger Deep's desert-like seafloor and gliding along its cliff walls, the whole time collecting samples and video.
Among the 2.5-story-tall sub's tools are a sediment sampler, a robotic claw, a "slurp gun" for sucking up small seacreatures for study at the surface, and temperature, salinity, and pressure gauges. (See pictures of Cameron's sub.)
Now "the science team is getting ready for the returned samples," said NASA's Hand.
Cameron—best known for creating fictional worlds on film (Avatar, Titanic, The Abyss)—is expected to announce his initial findings later today. After analysis, full results are to be published in a future edition of National Geographic magazine.
