Submersibles Through Time

About 99 percent of our planet's living space lies underwater, with a dizzying variety of organisms thriving from the surface to the scorching waters of our deepest ocean vents miles below. Submersibles, not surprisingly, have played a key role in exploring and understanding this last frontier. Reaching astounding depths and capable of performing complicated scientific experiments, these advanced craft have even begun to tease out clues to the origin of life and the formation of our planet. In this time line, see just how imaginatively these underwater dream machines have evolved over the decades.—Rima Chaddha
