On July 16, 1969, a rocket in Cape Canaveral, Florida launched three humans into space, destination moon. They were hurtled away from Earth with the help of NASA's Saturn V rocket -- and with the help of, at the rocket's base, five Rocketdyne F-1 engines. This was a lot of help. According to a 1965 press release (pdf), "The F-1 is the most powerful rocket engine to be ordered into production in the United States. It is a single chamber, liquid propellant engine of conventional, proven design developing 1,500,000 pounds of thrust." And despite all the advances we've made since then in the broad field of rocket science, the F-1 remains the most powerful single-chamber liquid-fueled rocket engine ever developed.
And yet. The engines, like so many of the instruments we devise to send ourselves into space, were useful only briefly: The F-1s had a practical shelf life of about 165 seconds. After the Saturn V and its passengers had gotten the boost they needed, the engines were jettisoned: five scarred, metal cones sent hurtling into the waters of the Atlantic.
The engines were relegated to the sea floor -- until now. Two of the Saturn V engines have now been recovered from their watery, and only temporary, graves. And they've been surfaced by Jeff Bezos. (Yes, that Jeff Bezos.) The Amazon CEO's other company, the space technology firm Blue Origin, has recovered a pair of first-stage engines so they can be studied, restored, and, later, displayed to the public. ("The objects themselves," Bezos says, "are gorgeous."
The engines' deep-sea recovery is the product of a long process of maritime archaeology: Last year -- almost exactly a year ago -- Bezos and his team announced that they had, using sonar, located the Saturn V engines in the depths of the Atlantic. Once they made that discovery, they set to work getting those objects to the surface -- with the help of remote operated vehicles and a large crew of humans.

(16,993 posts)There's junk floating around the planet as well as on the ocean floor, left over from various missions. Is it not enough to pollute the planet and our atmosphere? Now we have to trash space as well!
Create some jobs and clean up the trash!
