The deadly implosion of an experimental submersible en route to the deep-sea grave of the Titanic last June has not dulled the desire for deep-sea exploration. Tuesday, June 18, 2024, marks one year since the Titan vanished on its way to the historic wreckage site. (Paul Daly/The Canadian Press via AP, File)
