Quick Answer

An unmanned vehicle first reached the Challenger Deep in 1965. That marked an important step toward robotic deep-ocean exploration.

The Full Story

An unmanned submersible reached the Challenger Deep in 1965, only a few years after the first crewed descent. Robotic and remotely operated vehicles gradually became crucial for exploring the ocean’s deepest regions. They could stay down longer, carry cameras and instruments, and go places too dangerous for people. This changed deep-sea science by making it possible to map, sample, and observe extreme environments in detail. Today, autonomous and remote systems are indispensable in marine research.
