Explorer and filmmaker James Cameron pulled together a diverse team from all over the world to make the first attempt to dive to Challenger Deep in more than 50 years—the only solo dive ever. Here's a behind-the-scenes look from a key team member. It's a completely hostile world nearly 7 miles (10.9 km) beneath the ocean's surface. No light, temperatures just above freezing, and 16,000 lbs of pressure per square inch. That's Challenger Deep. Can anything live there? Can anyone survive the trip to find out? Chosen for its reliability and ability to communicate with a wide variety of other systems, the SNAP PAC System keeps the pilot of Deepsea Challenger informed about everything going on in the sub.
