It's amazing that they could find something that "small" in the freaking ocean.


With side-scan sonar you can get very detailed images of large areas of sea floor rather quickly, then you send down robotic submersibles studded with cameras and lights to check out suspicious targets.

There is talk of using an upgraded F-1 engine, the F-1A which was designed but never flown, in liquid side boosters for the NASA SLS (Space Launch System) launcher. It would initially use solids, upgraded and lengthened units based on the Shuttle SRB's, then evolve to liquid side boosters.

The SLS is designed to use RS-25 engines (4) which are really just upgraded Shuttle main engines, not the F1.

That's for the core (center) stage. I'm talking about the side boosters.

Initially the side boosters will be solids made by ATK, but later NASA plans on a competition between those and liquid fueled alternatives. There are 2 major liquid engine alternatives;

• The Aerojet AJ26-500, an evolved and up-powered version of the AJ26 being used in Orbital Science's Antares launcher, which itself is derived from the Russian NK-33.

• The F-1. Last year Rocketdyne and Dynetics propsed the F-1 option, and NASA pulled F-1 #6049 (removed from Apollo 11 for fit reasons), scanned and duplicated its gas generator to see if modern manufacturing techniques could be used to resurrect it but made cheaper.

11 F-1 gas generator firings were completed at Marshall earlier this year and now it seems the F-1 is back on the table.

Confirmed: Engine #5, S/N 2044 from Apollo 11

Apollo 11 F-1 Engine Finding Confirmed by Jeff Bezos on Eve of 1st Human Moonwalk

In a fitting testament to NASA’s momentous Apollo Moon Landing Program, NASA and billionaire Jeff Bezos confirmed today the discovery of a powerful F-1 first stage engine component from the Saturn V moon rocket that launched three American astronauts on the historic journey of Apollo 11 to land the first two humans on the Moon on July 20, 1969.

“On the eve of the 44th moonwalk anniversary, the Bezos Expedition confirms an Apollo 11 Saturn V F1 engine find,” NASA officially announced on its websites just moments ago.

Apollo 11 commander and NASA astronaut Neil Armstrong, was immortalized forever when he first set foot on the moon 44 years ago tomorrow (July 20, 1969), followed minutes later by the lunar module pilot, NASA astronaut Buzz Aldrin.

The Saturn V rockets first stage was powered by a cluster of five F-1 engines – a technological marvel and the most powerful single-nozzle, liquid-fueled rocket engine ever developed.

Bezos, founder and Chief Executive Officer of the aerospace company Blue Origin and Amazon.com, announced the discovery and recovery of significant components of two flown F-1 engines amongst a field of twisted wreckage from the floor of the Atlantic Ocean in March of this year, aboard the Seabed Worker at Port Canaveral, Florida, along with a treasure trove of other major Saturn V components hauled up from a depth of almost 3 miles.

“We brought back thrust chambers, gas generators, injectors, heat exchangers, turbines, fuel manifolds and dozens of other artifacts – all simply gorgeous and a striking testament to the Apollo program,” wrote Bezos in a update this morning, July 19.

But until today, the engines exact identification remained elusive because of decades of severe seabed corrosion and their fiery, destructive end upon plunging and smashing unimpeded onto the ocean’s surface.

Conservators from the Kansas Cosmosphere and Space Center in Hutchinson, Kansas worked painstakingly since March to identify the F-1 engine parts.

“Today, I’m thrilled to share some exciting news. One of the conservators who was scanning the objects with a black light and a special lens filter has made a breakthrough discovery – “2044” – stenciled in black paint on the side of one of the massive thrust chambers, says Bezos.

“2044 is the Rocketdyne serial number that correlates to NASA number 6044, which is the serial number for F-1 Engine #5 from Apollo 11. The intrepid conservator kept digging for more evidence, and after removing more corrosion at the base of the same thrust chamber, he found it – “Unit No 2044″ – stamped into the metal surface.”

“44 years ago tomorrow Neil Armstrong stepped onto the moon, and now we have recovered a critical technological marvel that made it all possible.”

The five F-1 engines used in the 138-foot-tall Saturn V first stage known as the S-IC generated 7.5 million pounds of liftoff thrust, or some 1.5 million pounds each. They stand 19 feet tall by 12 feet wide. Each one weighs over 18,000 pounds and was manufactured by Rocketdyne.

The F-1 had more power than all three space shuttle main engines combined. They burned a mixture of liquid oxygen and kerosene fuel for two-and-one-half-minutes, carrying the Saturn V to an altitude of some 36 miles.

Altogether, six Apollo Moon landing flights boosted by Saturn V’s sent a total of 12 humans on moon walking expeditions to Earth’s nearest neighbor during the 1960s and 1970s.

“This is a big milestone for the project and the whole team couldn’t be more excited to share it with you all,” Bezos wrote.

Bezos’ Blue Origin firm is also working to develop a commercial rocket and ‘space taxi’ to finally resume launching American astronauts back to low Earth orbit from American soil after a multi year gap.

More than four decades have passed since the last humans traversed the lunar surface in December 1972 during NASA’s Apollo 17 moon landing mission.

After all that time, the F-1 may yet live again.

NASA is now working on an upgraded F-1 to power a future variant of the new SLS heavy lift booster under development and intended to launch humans aboard the new Orion crew capsule back to the Moon and to deep space destinations including Asteroids and Mars.

NASA’s robotic exploration of the moon continues this year with the blastoff of the LADEE Lunar observatory on Sept. 6 from NASA’s Wallops Island facility in Virginia.

What am I looking at in this sonar image exactly?

Looks like a ship to me.

Yup.
