Robots for deep-sea recovery missions in sci-fi and reality

A science fiction/science fact review of Three Miles Down by Harry Turtledove, the fictionalized version of the Hughes Glomar Explorer expedition 50 years before the OceanGate Titan tragedy.

My new science fiction/science fact article for Science Robotics is out on why deep ocean robotics is hard. Especially when trying to bring up a sunken submarine 3 miles underwater, which the CIA actually did in 1974. It’s even harder if you’re trying to bring up an alien spaceship- which is the plot of Harry Turtledove’s new sci-fi novel Three Miles Under. It’s a delightful Forrest Gump version of that 1974 Hughes Glomar Explorer expedition. Though the expedition was 50 years before the OceanGate Titan tragedy, the same challenges exist for today’s robots. The robotics science in the book is very real, the aliens, not so much.
