But there, most of the similarities end, because you are talking about a half century of technology.” Some features of the DEEPSEA CHALLENGER-including its lights and cameras-would have been beneficial had they existed in 1960. They are capable of withstanding great pressures. They carry people down to the deepest place in the ocean. That’s like asking Orville Wright what was the difference between your airplane and a 747,” he says. “People ask me what were the differences between the Trieste and the DEEPSEA CHALLENGER. “Once you look at it and see it, you realize it’s pretty simple.” Walsh is quick to note that the DEEPSEA CHALLENGER is far more technologically advanced than the sub he and Piccard used. Everybody thinks, ‘Why didn’t I think of that?’” he says. He was impressed by the simplicity of the vessel’s design.

“I think pretty much a free balloon that would fly in the sky-except the balloon part was sausage-shaped rather than spherical because that’s an easier shape to tow,” Walsh says. Attached to the bottom of the Trieste was a small, pressure-resistant sphere with enough room for just two people. The Trieste, in contrast, was designed like a hot air balloon, with a cylindrical top section composed of a float filled with gasoline and water to lift the vessel back to the surface after the dive. The DEEPSEA CHALLENGER resembles a rocket-a narrow, vertically oriented tube.
Designed by Piccard, the Trieste looks vastly different from the DEEPSEA CHALLENGER. Piccard died in 2008, but Walsh is still involved in ocean research and was a key adviser on Cameron’s team. Don Walsh and Swiss oceanographer Jacques Piccard reached the Challenger Deep in a submersible called the Trieste. Cameron used an innovative, sophisticated submersible, the DEEPSEA CHALLENGER. On March 26, 2012, National Geographic Explorer-in-Residence James Cameron made history by becoming the first person to make a solo dive to the deepest known part of the ocean, the Challenger Deep in the Mariana Trench, nearly 11 kilometers (7 miles) below the water’s surface.
