Salvagers backed by billionaire Jeff Bezos have recovered components from the Saturn 5 rocket engines that powered NASA's Apollo moon missions off the launch pad, more than four decades after they hurtled down to the bottom of the Atlantic Ocean.

Amazon.com's founder reported on the successful three-week sea salvage operation on his Bezos Expeditions website. "What an incredible adventure," he wrote.

"We've seen an underwater wonderland — an incredible sculpture garden of twisted F-1 engines that tells the story of a fiery and violent end, one that serves testament to the Apollo program," Bezos said Wednesday.

Almost a year ago, Bezos announced that deep-sea sonar scans had located the first-stage engines that were used for the historic Apollo 11 launch in 1969 — the launch that sent astronauts on their way to the moon's surface for the first time. The first stage of the three-stage Saturn 5 was jettisoned once its fuel was spent, and fell into the Atlantic.

It took months to plan the recovery expedition — and three weeks ago, Bezos and the salvage team headed out into the Atlantic on the Seabed Worker, a ship that has previously played a role in recovering sunken treasures.

"While I spent a reasonable chunk of time in my cabin emailing and working, it didn't keep me from getting to know the team," Bezos wrote. Much of his posting was given over to thank-yous for the team members. 

The chilly ocean waters preserved the hardware in "gorgeous" condition at a depth of more than 14,000 feet, Bezos said. He noted that it was difficult to make out the serial numbers on the hardware. Confirmation of the Apollo 11 connection will have to wait until the parts are more closely examined.

Remotely operated vehicles recovered enough components to fashion displays of two flown F-1 engines. Bezos said the ship was now on its way back to Cape Canaveral, Fla., to offload the artifacts. Bezos Expeditions said the restoration would take place at the Kansas Cosmosphere and Space Center.

"The upcoming restoration will stabilize the hardware and prevent further corrosion," Bezos said. "We want the hardware to tell its true story, including its 5,000 mile per hour re-entry and subsequent impact with the ocean surface. We’re excited to get this hardware on display where just maybe it will inspire something amazing."

Even before the expedition, Bezos and NASA worked out where the artifacts would be going. The first option would go to the Smithsonian Institution's National Air and Space Museum in Washington, NASA spokesman Bob Jacobs told NBC News in an email. The second engine would be offered to the Museum of Flight in Seattle, the hometown for Bezos and Amazon.com.

"While we have no role in the restoration, we are providing assistance to help identify the hardware through our various history offices and field centers," Jacobs said.

Although Bezos made his billions in the dot-com world, he's had a longstanding interest in spaceflight as well: His rocket venture, Blue Origin, has been working on a launch system for suborbital as well as orbital passenger flights with NASA's backing. Last year, Bezos donated a 5-ton Blue Origin lander prototype to the Museum of Flight.

In a statement, NASA Administrator Charles Bolden praised the recovery of the engines as a "historic find."

"We look forward to the restoration of these engines by the Bezos team and applaud Jeff’s desire to make these historic artifacts available for public display," Bolden said. "Jeff and his colleagues at Blue Origin are helping to usher in a new commercial era of space exploration, and we are confident that our continued collaboration will soon result in private human access to space, creating jobs and driving America’s leadership in innovation and exploration."

NASA

Among the spaceship projects receiving NASA support are Boeing Co.'s CST-100 capsule (left), Sierra Nevada Corp.'s Dream Chaser space plane (middle) and SpaceX's Dragon capsule (right).

Americans could be flying into orbit on U.S.-built spaceships again as early as 2015 — but the first fliers won't be NASA astronauts or millionaire space tourists. Instead, they'll be commercial test pilots, employed by the Boeing Co., Sierra Nevada Corp., SpaceX or maybe even a dark-horse company like Blue Origin, the venture funded by Amazon.com billionaire Jeff Bezos.

Those four companies provided updates on their efforts to build new spaceships capable of carrying astronauts to and from the International Space Station during a Wednesday news briefing at NASA's Kennedy Space Center. One of the companies, Blue Origin, is wrapping up its work for NASA and is no longer receiving money through the Commercial Crew Program, or CCP. But SpaceX, Boeing and Sierra Nevada are splitting more than $1 billion that's to be paid out through 2014.

NASA's manager for the Commercial Crew Program, Ed Mango, said the agency and its commercial partners are already talking about "Phase 2" for the program. The certification requirements and timetable for Phase 2 are expected to be set this year, with contracts awarded by May 2014, Mango said. "We believe that there’ll be more than one, probably two, three, maybe others, that will be ready to compete for Phase 2," he said.

That phase would move the program forward to 2017, by which time NASA expects to be flying its astronauts on U.S. launch vehicles for the first time since the shuttle fleet was retired in 2011. In the meantime, NASA will be paying the Russians more than $60 million per seat for round trips to the space station.

"Our target was to repatriate that industry back to the United States, and that's what we're doing," said Mark Sirangelo, chairman of SNC Space Systems at Sierra Nevada.

Here's how the companies' plans are shaping up:

SpaceX: Former NASA astronaut Garrett Reisman, SpaceX's commercial crew project manager, said his company is working toward a launch pad abort test by the end of the year at Kennedy Space Center. An in-flight test that would demonstrate the ability to abort a launch safely during ascent, "at the worst possible moment," is planned for April 2014, he said. If SpaceX sticks to its schedule, it would use its Falcon 9 rocket and Dragon capsule for a manned test flight in mid-2015, and would send test pilots to the space station by the end of 2015. "We're not selling tickets. Don't call our toll-free number," Reisman joked.

Sierra Nevada Corp.: Sirangelo said his company was planning to drop its Dream Chaser mini-shuttle from a carrier airplane for its first autonomous, free-flying glide test in the first quarter of this year. That would be followed by a series of autonomous and crewed aerodynamic test flights, similar to the tests conducted by NASA using the prototype shuttle Enterprise in the late 1970s. Then Sierra Nevada's team would launch the Dream Chaser into space — first on suborbital test flights, and eventually into orbit. Last year, the company said manned orbital flights could begin in 2016.

The Boeing Co.: John Mulholland, vice president and program manager for Boeing's commercial crew program, said his company proposed conducting a three-day orbital spaceflight with a Boeing crew in 2016. The head of Boeing's flight test program is former NASA astronaut Chris Ferguson, who commanded Atlantis' crew during the final flight of the shuttle program. "He is defining crew requirements," Mulholland said. Before the test pilots fly, Boeing will conduct an unmanned orbital trial of its CST-100 space capsule, plus an altitude abort test.

NASA / Blue Origin

Blue Origin: The company that Bezos founded in 2000 is not receiving NASA funding during the current phase of the agency's spaceship development program — but Blue Origin's president and program manager, Rob Meyerson, said he's still doing business with the space agency. "We're working with NASA to extend our Space Act Agreement in an unfunded manner," Meyerson said. The company is continuing to test its BE-3 rocket engine and work on its next prototype propulsion vehicle. Eventually, Blue Origin aims to launch crews on suborbital as well as orbital spaceflights.

The plans for future flights are dependent on continued NASA support — and Phil McAlister, NASA's commercial spaceflight development director, acknowledged that "the budget is going to be an extremely challenging topic."

If NASA's funding is reduced, Reisman said his company would continue to move toward manned flights, but at a slower pace. "Human spaceflight is our reason for being. We are in this for the long haul," Reisman said. "There will be impacts to cost and schedule, should funding dry up. But we're going to get there eventually."

If you think America's space effort is in a state of flux now, you ain't seen nothing yet: Just wait until billionaires Richard Branson and Robert Bigelow are vying to offer orbital hotels, or until there are as many brands of spaceships built in the United States as commercial jets.

Or not.

That's the curious thing about Space Race 2.0: It's definitely a marathon, not a sprint, and the field of contestants have had dropouts (like the bankrupt Rocketplane Kistler) as well as drop-ins (like the Boeing Co.).

If any of the racers make it to the finish line, NASA will once again be able to send U.S. astronauts to the International Space Station on U.S.-built spacecraft, ending the post-shuttle spaceship gap. There may also be opportunities for businesses and foreign governments to purchase their own presence in space, in the form of private-sector space stations. Regular folks may be able to buy vacation packages that include a quick up-and-down on a suborbital spacecraft, or even a stay on one of those space stations.

There'll be new opportunities for space research and manufacturing as well. Alan Stern, a planetary scientist at the Southwest Research Institution as well as an adviser to the Blue Origin space venture, has called low-cost space research the "killer app" for the space travel industry — right up there with space tourism and space station resupply.

But what steps lie ahead for private space ventures, and what's the time frame for taking those steps?

A crucial year
For the companies seeking NASA's business, the next six months to a year will be crucial: Four companies — Blue Origin, Boeing, Sierra Nevada Corp. and SpaceX — are receiving hundreds of millions of dollars from NASA to develop spaceships capable of ferrying astronauts to the space station and back. SpaceX and yet another company, Orbital Sciences Corp., have already been receiving NASA funding to support the development of unmanned cargo spaceships.

In February, SpaceX is due to launch a test cargo shipment to the space station and bring the capsule back to Earth. Orbital Sciences, meanwhile, is gearing up for its first test flight of its Taurus 2 launch vehicle in the same time frame. By 2013, both companies should be cleared for orbital cargo deliveries as part of a $3.5 billion combined deal with NASA.

The development effort for crew vehicles is more complex, due to the higher safety requirements. Last month, Congress settled on an allocation of $406 million for the next phase of the commercial crew development program, or CCDev. That's less than half of the $850 million requested by the Obama administration, and NASA hasn't yet laid out a revised plan for the next development round.

Based on the space agency's previously announced plans, the money for the next phase would be given out starting next July, for the development of an integrated system that includes a space-taxi capsule as well as the rocket it rides on. SpaceX can already offer the full package, which combines its Falcon 9 rocket with its Dragon capsule. The other contenders will have to buddy up with rocket builders — either United Launch Alliance, which offers the Atlas 5; or ATK and EADS Astrium, which have proposed creating a hybrid rocket called Liberty. Right now, the Atlas 5 is the favored vehicle in the rocket race, but the next phase of CCDev provides an opportunity for dark horses like ATK to get back in the race.

As long as no one crosses the finish line, NASA is stuck in the position of paying the Russians $50 million or more for each seat filled by a U.S. astronaut heading to the space station. So the space agency has a powerful interest in making sure that at least one space-taxi operator succeeds. NASA expects that it'll be using U.S.-built space taxis in the 2017 time frame, but warns that reduced funding levels will slow down the timeline.

Suborbital space race
Meanwhile, additional companies are aiming for suborbital space business, either for research or tourism purposes. Among the major players in this particular race are Armadillo Aerospace, Virgin Galactic and XCOR Aerospace,

Virgin Galactic says it's on track to begin powered test flights of its SpaceShipTwo craft early next year, with an eye toward offering suborbital trips at $200,000 a seat in 2013. Branson, the company's founder, is aiming even higher: "We're starting by suborbital trips, we'll then go to orbital trips, we're then going to look at space hotels. We're going to look at intercontinental travel at a speed much quicker than you can currently travel," he told me during an interview in October.

XCOR Aerospace plans to start testing its Lynx rocket plane in the air within a year, and wants to take on tourists starting in the 2013-2014 time frame.

Armadillo has partnered up with Space Adventures, the company that has sent seven paying passengers to the space station, to develop a suborbital launch system capable of carrying passengers or scientific experiments. The New Mexico Spaceport Authority says Armadillo ran a successful test of a reusable sounding rocket known as STIG A on Dec. 4. The rocket rose to an altitude of 137,500 feet (41.91 kilometers), and carried a scientific package from Purdue.

Blue Origin, which was founded by Amazon.com billionaire Jeff Bezos, is also working on a suborbital spaceship project that's separate from the NASA-funded orbital effort. (The company is bouncing back from the crash of a suborbital test vehicle in August.)

Next giant leap
Of course, there's no guarantee that any of these companies will get off the ground on the timetable they expect. This space race is notorious for slowing down the pace: Spaceship builders have been predicting that the golden age of private spaceflight is just two years away for the past 15 years.

The interesting thing is that the different companies are coming together in combinations that make the space race look more like a square dance: Space Adventures is teaming with Armadillo on suborbital tourism, with Boeing on orbital tourism, and with the Russians on trips to the space station and even the moon. Sierra Nevada is relying on Virgin Galactic's help for atmospheric tests of its prototype orbital vehicle, while Virgin Galactic is relying on Sierra Nevada to provide the hybrid rocket engine for SpaceShipTwo. Boeing is a partner with Lockheed Martin in United Launch Alliance, which plans to provide rockets for Boeing as well as two of its CCDev competitors.

Bigelow Aerospace, which has already put two of its inflatable space modules into orbit on Russian rockets, could conceivably purchase launch services from SpaceX or United Launch Alliance to establish future private-sector space stations — and it's teaming up with Boeing and Space Adventures to make the arrangements for orbital trips by tourists and researchers.

Where could all this lead? Would you believe to Mars? At least that's what SpaceX founder Elon Musk expects. He's teaming up with NASA's Ames Research Center on a proposal for an unmanned Mars mission in the 2018 time frame, and he has said SpaceX's rockets could send humans to Mars in the next 10 to 15 years if that's what NASA wants to do.

"The reason to do space and to try to push the boundary of space is that it's one of the coolest things that humanity, or we as a country, can do," he told me. "We want there to be cool things. Life cannot just be about solving problems. If that's all it's about, why get up in the morning? There's got to be things that are inspiring and make life worth living — and I think pushing the boundaries of space and the outer frontier is one of those things."
