In a fitting testament to NASA’s momentous Apollo Moon Landing Program, NASA and billionaire Jeff Bezos confirmed today (July 19) 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 today, July 19.
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.
“44 years ago tomorrow Neil Armstrong stepped onto the moon, and now we have recovered a critical technological marvel that made it all possible,” says Bezos on his Expedition website today.
Bezos, founder and Chief Executive Officer of the aerospace company Blue Origin and Amazon.com, originally 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.”
Apollo 11 launched to the Moon on July 16, 1969 from Launch Complex 39-A at the Kennedy Space Center in Florida.
Armstrong and Aldrin landed on the Sea of Tranquility inside the Lunar Module. They took a single lunar excursion and spent 2 hours and 11 minutes as the first two men to walk on the moon. They stayed on the moon for a total of 21 hours and 36 minutes before blasting off for the journey back home to Earth.
Armstrong suddenly passed away nearly a year ago on August 25, 2012 at age 82 – read my stories, here and here.
Aldrin is still active and strenuously advocating for starting human expeditions to the Red Planet.
He outlined his exploration concepts in a newly published book titled – “Mission to Mars.”
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.
