In January 1960, oceanographer Jacques Piccard and Navy Lieutenant Don Walsh boarded the bathyscaphe *Trieste* to attempt a historic descent to the deepest known point in the Earth's oceans: the Challenger Deep in the Mariana Trench. As they descended into the abyss, the temperature inside the cabin dropped significantly, and a window pane cracked under the immense pressure. Despite these dangers, the team of intrepid explorers were observing a surprising variety of marine life, documented their findings, and began their ascent back to the surface.
