F-1 Rocket Engine Recovery

They took rocket-grade kerosene and liquid oxygen, and turned it into 1.5 million pounds of thrust, 32 million horsepower, and made it possible to take the Apollo astronauts to the Moon. I’m talking about the Rocketdyne F-1 rocket engines used in the first stage of Saturn V — the only vehicle to take humans outside of low-Earth orbit.

Following launch, five F-1 engines would burn for about 2-and-one-half minutes, boosting the Saturn V and its payload to an altitude of nearly forty miles, and 55 miles downrange from Cape Kennedy. At that point, the first stage (S-1C) containing the F1 engines would separate from the rest of the Saturn V and fall back to Earth, crashing into the Atlantic Ocean where they would rest forever.

At least, forever was how long we thought they would sit there….

Amazon.com founder, Jeff Bezos, recently announced that a “team of undersea pros” that he funded had found the most famous F-1 engines of all; the ones from Apollo 11 that launched humanity to the Moon, where the first humans would walk on another world. But finding them is just the start, Bezos Expeditions is planning on actually recovering one or more of the F-1s.

“We don’t know yet what condition these engines might be in – they hit the ocean at high velocity and have been in salt water for more than 40 years. On the other hand, they’re made of tough stuff, so we’ll see”, Bezos said in the announcement. He also pointed out that regardless of how long the engines have spent 14,000 feet below the surface of the Atlantic, they are still the sole property of NASA. He also stated that he had requested that NASA make available for display at the Museum of Flight in Seattle, Washington, the second F-1 his group manages to salvage (the first presumably would go to the Smithsonian).

NASA followed the announcement with a press release of their own, in which NASA Administrator Charles Bolden expressed his support for the project, and acknowledged the request to house a second (or the first, if the Smithsonian declines it) F-1 at Bezos’ requested facility.

“NASA does retain ownership of any artifacts recovered and would likely offer one of the Saturn V F-1 engines to the Smithsonian Institution’s National Air and Space Museum in Washington under long-standing arrangements with the institution as the holder of the national collection of aerospace artifacts.

“If the Smithsonian declines or if a second engine is recovered, we will work to ensure an engine or other artifacts are available for display at the Museum of Flight in Seattle, as Jeff requested in his correspondence with my office.”

As of yet, there hasn’t been an announced timeline, cost, or specific details released about the project; however, I personally suspect Bezos will have no problem pulling together the resources needed to tackle the feat.

Bezos ended the announcement with a quote that echoes my own heart when it comes to NASA’s ability to inspire:

NASA is one of the few institutions I know that can inspire five-year-olds. It sure inspired me, and with this endeavor, maybe we can inspire a few more youth to invent and explore.

Good luck, Bezos Industries. Thanks for taking the public treasure that NASA is and multiplying its inspiration for generations to come.
