Fabien Cousteau, grandson of famed ocean explorer Jacques Cousteau, and a team of fellow aquanauts on Sunday will dive down to Aquarius Reef Base, an undersea lab 63 feet down in the Florida Keys National Marine Sanctuary. They plan to make the school-bus-size lab their home for 31 days, while exploring the deep and conducting scientific research -- all the while broadcasting the mission live.
Liz Magee, seen here next to Aquarius Reef Base, will be part of the second wave of aquanauts joining the expedition.

A monthlong mission takes extensive planning. That includes
preparing in case something goes wrong.
