Pittsburgh professor Alex Waibel is proud to call himself an explorer, but today he’s mourning. All this week, a lot of the world was sort of obsessed with the rescue efforts for the submersible that went missing on its descent to the Titanic shipwreck. A big part of the problem was how the sub and others like it communicate with would-be support above water, and Waibel had been working on a way to solve that. Last summer, he tested it on Titan, and he planned to return in a few months. Host Megan Harris connected with him from Germany, where he was waiting to hear the fates of his friends and former colleagues alongside everyone else.
