Meanwhile, somewhere beneath the Pacific.
The Apollo 13 LEM, Aquarius, may have partially survived
entry into Earth's atmosphere in April, 1970.
Not only may have the ceramic-lined radioactive device for electric power to its science station, but the two (titanium?) LEM rocket motors
may have also survived the entry and splashed into the Pacific.
I wonder if Dr. Ballard would be interested in hunting them down?
