Jules Jaffe, a research oceanographer with the Marine Physical Laboratory at Scripps Institution of Oceanography at the University of California, San Diego, sits at his home in La Jolla, California, on June 20, 2023. Deep-sea thrill-seeker Stockton Rush founded OceanGate in 2009 with the hopes of advancing submersible vehicle technology and taking travelers into the darkest depths of the ocean. During such a mission on June 18, 2023, the submersible -- with Rush onboard -- went missing, losing contact with the surface ship less than two hours after it began its descent. An international search effort was launched to try and find Rush and the four other passengers in the remote North Atlantic, but no sign of them has been found. (Photo by Sandy Huffaker / AFP)
