An underwater expedition led by Amazon CEO Jeff Bezos successfully recovered the mangled wreckage of two rocket engines from NASA’s Apollo Moon program from the bottom of the Atlantic Ocean. The F-1 engines, which powered the first-stage Saturn V boosters that fell back to Earth after their fuel was depleted, were found at a depth of 14,000 feet, Bezos’ expedition announced Wednesday. NASA will not try to determine on which Apollo mission the rocket engines were used. Thanks to Alaric Bond and Tony Seideman for passing the news along.
