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."

Blue Origin

Blue Origin's pusher escape system rockets the company's prototype crew capsule away from the launch pad, demonstrating a key safety system for both suborbital and orbital flights. Click on the picture to go to the Blue Origin website for a video of the test flight.

Amazon.com billionaire Jeff Bezos' Blue Origin rocket venture notched a blazing success last week when it tested a NASA-backed launch pad escape system for its crew capsule.

The Oct. 19 demonstration flight at Blue Origin's West Texas spaceport marked the final milestone for NASA's $22 million agreement with Blue Origin, which was aimed at promoting the development of next-generation spaceships capable of resupplying the International Space Station. Blue Origin, which is based in Kent, Wash., decided not to compete for the next phase of NASA's orbital program — but in a news release issued today, Bezos said his company would make use of the "pusher" pad escape system in its suborbital spaceship.

"The first test of our suborbital Crew Capsule is a big step on the way to safe, affordable space travel," he said. "This wouldn’t have been possible without NASA’s help, and the Blue Origin team worked hard and smart to design this system, build it, and pull off this test. Lots of smiles around here today. Gradatim Ferociter!"

That last phrase is Blue Origin's motto, which is Latin for "Step by Step, Courageously."

The latest step
The pad-escape test was the latest step in Bezos' decade-long effort to create a launch system suitable for space tourists as well as researchers and, eventually, orbit-bound astronauts. The 48-year-old Amazon.com founder, whose net worth is estimated at more than $23 billion, created Blue Origin in 2000 to follow through on his childhood dream of space travel. 

"Blue Origin's goal is to work steadily toward developing human spaceflight capabilities," Brett Alexander, the company's director of business development and strategy, told me today. "Our goal is to lower the cost and increase the safety of human spaceflight to enable more people to fly."

Blue Origin

Blue Origin's New Shepard crew capsule rose to a height of 2,307 feet before deploying its parachutes for a safe descent.

Blue Origin

The gumdrop-shaped crew capsule set down 1,630 feet from the launch pad. This closeup view focuses on Blue Origin's logo and motto: "Gradatim Ferociter."

Alexander said last week's pad-escape test in Texas and this month's successful test firing of Blue Origin's BE-3 liquid-hydrogen rocket engine at NASA's Stennis Space Center in Mississippi ranked among the biggest steps taken to date toward the company's goal. "This is a very big deal. ... Propulsion and crew escape are two of the fundamental building blocks of our system," Alexander said. "Those are the cornerstones, if you will."

Blue Origin is working toward the development of a New Shepard suborbital launch system with a propulsion module that can launch the crew capsule to an altitude beyond the 100-kilometer (62-mile) boundary of outer space. From that height, passengers can get a few minutes of weightlessness amid a view of the black sky above a curving Earth, while researchers can conduct useful experiments on the effects of the space environment.

Blue Origin hasn't laid out a specific schedule for commercial operations — nor has the company said anything about its pricing plan for spaceflights. But in order to be financially viable, the venture would probably have to be competitive with other suborbital spaceship companies, such as Space Adventures, Virgin Galactic and XCOR Aerospace. Those companies are offering flights in the range of $95,000 to $200,000 per seat.

Alexander said "the key to both safety and affordability is reusability of the launch vehicle and a lot of practice — a high flight rate."

End-to-end tryout
The pad-escape test served as an end-to-end tryout for Blue Origin's crew capsule: A center-mounted solid-rocket engine from Aerojet lofted the capsule to a height of 2,307 feet (703 meters) under active thrust vector control. Then the capsule descended by parachute to a soft landing 1,630 feet (496 meters) downrange, at the company's test facility on ranchland owned by Bezos, near Van Horn, Texas.

Blue Origin showed the blastoff and landing in a video lasting a minute and 45 seconds.

Ed Mango, the manager of NASA's Commercial Crew Program, said in a space agency statement that "it was awesome to see a spacecraft NASA played a role in developing take flight."

"The progress Blue Origin has made on its suborbital and orbital capabilities really is encouraging for the overall future of human spaceflight," Mango said. 

In an actual flight scenario, the escape system would be lit up only if Blue Origin's propulsion module experienced a problem serious enough to abort the flight. The passengers inside the crew capsule would be rocketed away to safety. If the flight proceeded normally, the crew capsule would separate from the propulsion module, coast to the edge of space, re-enter the atmosphere and descend to a parachute landing. The propulsion module, meanwhile, would autonomously perform its own rocket-powered vertical landing.

In August 2011, a prototype propulsion module went supersonic and rose to an altitude of 45,000 feet during a test flight — but when the vehicle became unstable, the flight had to be aborted and the rocket ship crashed to its doom. That's the kind of scenario that would bring the pad-escape system into play.

Alexander said Blue Origin was still working on the next version of the propulsion module. The old version used five kerosene-fueled engines, but the next-generation propulsion module will use a single hydrogen-fueled engine, he said. "It'll look a little different, but it's essentially the same size," he said.

In the past, Blue Origin has been somewhat reticent to talk about its activities  but in light of the past month's successes, Alexander seemed to emphasize the sentiment behind the company's motto: step by step, courageously.

"Our overall development path certainly doesn't stop with suborbital," he said.

Blue Origin's jet-powered Charon test vehicle is brought inside Seattle's Museum of Flight.

Blue Origin, the rocket venture backed by Amazon.com billionaire founder Jeff Bezos, is sharing a 9,500-pound hunk of its little-known history — in the form of its first flying vehicle, a jet-powered lander prototype known as Charon.

The behemoth went on display this week in the Charles Simonyi Space Gallery at Seattle's Museum of Flight, which will also house a full-scale space shuttle training mockup.

Before this week, few folks outside Bezos' venture ever heard of Charon. The takeoff-and-landing platform was powered by four vertically mounted jet engines — and flew only once, on March 5, 2005, in Moses Lake, Wash. It rose to a height of 316 feet, then settled back down to a controlled landing.

Charon was moved into the museum on Tuesday and unveiled to the public on Wednesday.

"We are proud to share this piece of our company history with the Museum of Flight," Rob Meyerson, president and program manager of Blue Origin, said in a statement released by the company. "By making the original Charon vehicle available for public viewing, we hope to educate and inspire the next generation of aerospace explorers."

The technologies pioneered by Charon were applied to Blue Origin's vertical-takeoff-and-landing rocket ships — including the Goddard prototype that flew for the first time in November 2006 at Bezos' Texas spaceport, and the more capable test craft that followed. Last year, Blue Origin sent its prototype craft for suborbital space missions up to an altitude of 45,000 feet at supersonic speed — but Bezos reported that the flight had to be terminated with the loss of the vehicle, due to a flight instability that cropped up during the test.

Blue Origin's Charon lander prototype is settled in its spot inside the museum.

Blue Origin is working on a new prototype for its suborbital space program, which aims to carry passengers and research payloads beyond the 100-kilometer (62-mile) boundary of outer space. At the same time, it's receiving millions of dollars from NASA to help with the development of an orbital space vehicle that could service the International Space Station.

Historically, Bezos and Blue Origin have played their cards close to the vest — but in recent months, the venture has been more open about its ambitions and its progress. That's in line with the model being set by another space-minded billionaire, Elon Musk, the founder of California-based SpaceX.

Seattle's Museum of Flight stands to benefit because Blue Origin and Amazon.com are both headquartered in the Seattle area. "Blue Origin is making incredible strides in bringing commercial space travel to fruition," Douglas King, the museum's president and CEO, said in the statement. "Charon is an exciting addition to our extensive collection of historically significant air- and spacecraft. The fact that it comes from a company in our hometown makes it even more prestigious."

King is angling to acquire artifacts from other space ventures, ranging from SpaceX to the Boeing Co. Seattle-area software billionaire Charles Simonyi has already donated a used Russian Soyuz spacecraft for display. The piece de resistance will be the shuttle mockup, known more formally as the Full Fuselage Trainer, which is currently in the midst of being transported to the museum from NASA's Johnson Space Center. The trainer is expected to be assembled in its new home by the end of the summer.

More ventures backed by space billionaires:

• Billionaires back Seattle-based asteroid mining project
• SpaceX billionaire Elon Musk elated by successful launch
• Billionaire Paul Allen plans monster plane for space launches

Correction for noon ET May 25: I originally wrote that Charon was pronounced "CARE-on," like the name of the mythical Greek ferryman of the underworld. Actually, Blue Origin's Charon was named after Pluto's largest moon. That suggests that the name should be pronounced "SHAR-on," for reasons I explain on page 56 of "The Case for Pluto."

Blue Origin

This computational fluid dynamics simulation shows Blue Origin's orbital Space Vehicle with a body flap placed toward the spacecraft's aft end. More than 180 wind-tunnel tests were used to analyze design alternatives.

Executives at Blue Origin, the rocket venture founded by Amazon billionaire Jeff Bezos, have traditionally been reticent about discussing where they're going — but now that they're focusing in on development work for NASA, they're speaking out about their progress and their ambitions. And it turns out that those ambitions are ... well, pretty ambitious.

Like Armadillo Aerospace, Blue is developing a vertical-takeoff suborbital space vehicle for tourists and researchers. Like Sierra Nevada Corp., it's working on an aerodynamic spacecraft to carry NASA astronauts and other spacefliers into orbit. And like SpaceX, it's working on its own launch vehicles as well. The company may not provide many specifics about its timeline, but that doesn't mean the pace is lackadaisical.

"It's not a question of, 'Are we on some timeline,'" Brett Alexander, Blue Origin's director of strategy and business development, told me last week. "We've always said 'later in this decade' is when we're going to do it. Working with NASA will just accelerate us."

Alexander, who has worked on aerospace issues for more than two decades in government and industry circles, discussed Blue Origin's blue-sky ambitions as a follow-up to last week's news about a successful round of wind-tunnel tests for its orbital Space Vehicle, or SV. He said more than 180 runs were conducted at Lockheed Martin's wind-tunnel facility in Dallas to work out the right placement of aerodynamic body flaps on the aft end of the spacecraft.

The idea is that the flaps will enhance SV's biconic shape to give the capsule an extra bit of cross-range maneuverability "without the weight penalty and the complexity of wheels and wings," Alexander said. That could allow for a quicker return to orbit in the event of an emergency, since the SV could more easily be guided to a parachute-slowed descent over a designated land range.

May is a big month for Blue
Alexander said the resulting spacecraft design "will be officially blessed" at a system requirements review in May. Also during May, Blue Origin expects to begin testing of the thrust chamber assembly for its BE-3 rocket engine at NASA's Stennis Space Center in Mississippi, Alexander said.

The company, based in Kent, Wash., is receiving $22 million from NASA during the current phase of the space agency's program to help commercial ventures develop space taxis for the post-shuttle era. The SV isn't nearly as big as the space shuttle, of course, but it should be capable of transporting up to seven passengers to and from the International Space Station.

Alexander declined to say definitively whether Blue Origin would apply for further NASA funding during the next phase of the effort, known as Commercial Crew Integrated Capability or CCiCap. But with or without the money from NASA, Bezos and his team intend to create its their very own space transportation system.

"We started this design before NASA had the commercial crew program," Alexander said. "It was always our intention — and still is — to develop this."

He said that the plan calls for the "first few flights" to be launched on United Launch Alliance's Atlas 5 rocket, and that Blue Origin will eventually switch to its own launch vehicle with a reusable first stage.

Suborbital craft as 'pathfinder'
In parallel with its orbital development effort for NASA, Blue Origin is working on a separate crew capsule and propulsion vehicle that would blast off vertically for suborbital space trips. That part of the space program came into the spotlight last August, when Blue's unmanned test rocket went awry and crashed at the end of a supersonic test flight at Bezos' private spaceport in Texas. At the time, Bezos said that his team was "already working on our next development vehicle." Last week, Alexander said the development effort was "still under way."

In February, Alexander told Flightglobal that the suborbital crew capsule was undergoing testing, and that a pad-abort test would be conducted "in the summer sometime."

Although the funding arrangements for the privately backed suborbital program and the NASA-supported orbital program may be different, the two programs support each other technologically.

"Suborbital is definitely a pathfinder for our orbital system," Alexander said. The implication is that Blue Origin's rockets will be taking tourists and researchers to the edge of space significantly earlier than they'll be taking astronauts to orbit.

Bezos, whose net worth is currently estimated at more than $20 billion, doesn't strictly need NASA's money to pursue his long-held space ambitions. But Alexander said government backing will quicken Blue Origin's pace, and he argued against the sentiment in Congress that NASA should select just one company as the "leader" to go forward with spaceship development. Right now, NASA is supporting development efforts at four companies — the Boeing Co., Sierra Nevada Corp. and SpaceX as well as Blue Origin — and observers expect the field to shrink for the next round of funding. It's just a question of how much shrinkage there'll be.

"Competition is definitely better — better for the program, better for the country, better for the future of human spaceflight," Alexander told me. "If they down-select to one, it's no longer a commercial space program."

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."

Blue Origin

Blue Origin, the secretive rocket venture founded by Amazon.com billionaire Jeff Bezos, has unveiled a spruced-up website that includes videos of its successful "short hop" flight test back in May.

However, there's no new information about the crash of its PM-2 prototype in August, which came at the end of an ambitious supersonic tryout. Bezos acknowledged the crash a week after it happened in an online update, and said his team was already working on a new prototype. In Thursday's update, he made no mention of August's setback or the state of the development effort.

"We’ve received requests for video of the short hop test flight that took place earlier this year. Here are two videos of the flight," Bezos wrote. "Enjoy!"

The two videos show the PM-2 rising from the launch pad at Bezos' spaceport in West Texas, then easing back down to earth with engines blazing and dust flying. One video provides a fisheye view from near the launch pad, and the other video was taken with a handheld camera from a remote location.

Thursday's update is part of a redesigned website that lays out Blue Origin's spaceflight plans and highlights the venture's employment opportunities (including 14 "immediate openings" and a summer internship program).

Blue Origin intends to field a suborbital space vehicle known as New Shepard, which could take on tourists as well as researchers and their experiments. It's also working on an orbital space capsule capable of taking astronauts to the International Space Station. For orbital missions, Blue Origin has said it intends to use expendable Atlas 5 rockets at first but will eventually switch to its own reusable first-stage booster and upper stage.

The upgraded website provides more details about the suborbital as well as the orbital effort, including diagrams of the space vehicles and the "Cabin Payload Bays" that will hold experiments.

"The technical challenges of escaping Earth’s gravity well and reaching orbit have never been trivial, and are compounded when higher reliability and lower cost are required," Blue Origin says. "We are working patiently, step by step, to reach these long-term goals."

Over the past couple of years, NASA has set aside $25.7 million to support work on Blue Origin's orbital vehicle. Three other companies — the Boeing Co., Sierra Nevada Corp. and SpaceX — are currently receiving higher levels of support for similar spaceship development efforts. All four companies say they can have their orbital spaceships ready for NASA's use by around the middle of the decade, assuming that they continue to receive development funding from the space agency.

With the shuttle program winding down, the future of American spaceflight may well depend on how starry-eyed tycoons spend their money — and some of NASA’s money as well.

Three of the four companies that are in line to receive $269.3 million from NASA for building future spaceships are privately held, and what's more, they're led by well-off individuals who have at least a hint of intrigue about them. The fourth company, Boeing, is partnering with Bigelow Aerospace, which was founded by hotel-chain billionaire Robert Bigelow and has its own orbital aspirations.

NASA has laid out a plan for paying out the money over the next year or so, with the aim of promoting the rise of a new set of spaceship operators in the post-shuttle era.

In a commentary, George Washington University communication researcher Linda Billings picks up on the fact that hundreds of millions of taxpayer dollars are going to ventures that are headed up by folks who already have hundreds of millions of dollars.

"Why do these 'commercial' space companies need government handouts?" she asks. "The awardees are not hard-up start-ups (and these government handouts are not their first)."

It's true that all four companies have received money from the federal government previously, but none of those companies would characterize the payments as "handouts" or "subsidies."

They'd see them instead as payments for services rendered, goods delivered, or milestones achieved along the path that NASA wants them to take. And the $50 million that's been paid out so far under NASA's Commercial Crew Development program, or CCDev, is dwarfed by the $9 billion paid to commercial providers such as Lockheed Martin for the development of NASA's now-canceled Ares 1 rocket and now-downsized Orion crew capsule.

Although the financial details are hard to come by, it's virtually certain that the four companies have already spent far more than they've received for their spaceship projects. It's also virtually certain that not all four projects will make it into orbit. Because NASA is spreading out its bets, failure is definitely an option.

Here's a recap on the four spaceship development projects that NASA will be supporting for the next year under the second phase of the CCDev program. I'll be focusing on these efforts on Saturday during a Second Life chat about the post-shuttle spaceflight era, presented by the Meta Institute for Computational Astrophysics at 1 p.m. ET (10 a.m. SLT/PT):

Blue Origin

Blue Origin's orbital space vehicle is designed to take on trips to the International Space Station.

Blue Origin: The venture getting the least amount of money ($22 million) is arguably the most mysterious of the bunch. Amazon.com's billionaire founder, Jeff Bezos, set up Blue Origin in 2000 to follow through on his childhood dream of going into outer space. He has the country's only privately owned spaceport, nestled amid his 165,000-acre ranch in West Texas — and until CCDev came along, most people assumed he was targeting solely suborbital space tourism.

CCDev made clear that Bezos had higher ambitions: Blue Origin's agreement with NASA, made public in redacted form this week, shows that the company aims to build an orbital launch system capable of getting seven passengers to the International Space Station (or other destinations in low Earth orbit). Its space vehicle would initially be launched on an expendable rocket such as United Launch Alliance's Atlas 5, and eventually Blue Origin plans to field its own reusable rocket.

The suborbital effort is now seen as an interim step along the way to orbit. "The suborbital vehicle will be fully reusable and capable of flying three or more astronauts to an altitude of over 328,000 feet (above 100 kilometers) for science research and adventure," Blue Origin said. "The suborbital booster is currently undergoing integrated testing. ... The suborbital capsule will baseline key technologies for the orbital space vehicle, and is currently undergoing final assembly."

With rare exceptions, the only information publicly available about Blue's plans comes from government documents that must be made publicly available, such as the one released this week. Thus, it's hard to tell how much money Bezos has put into his rocket venture so far. But when you consider the construction costs for Blue Origin's production facility in Washington state, plus its facilities in Texas, plus all the testing it's done to date, it's unquestionably more than the $3.7 million the venture received under CCDev1 plus the $22 million it's due to get under CCDev2.

Blue Origin's partners include NASA's Ames Research Center and Stennis Space Center, United Launch Alliance and Lockheed Martin, Aerojet and the Air Force Holloman High Speed Test Track in New Mexico. The company's agreement with NASA says that Bezos "recognizes that successful development of an innovative space launch capability is a long-term endeavor and is committed to steady funding for development efforts to achieve a commercial orbital vehicle."

The company said NASA's support would "accelerate" the development of a reusable crew transportation system. "We are very pleased to continue working with NASA on development of our Crew Transportation System, and appreciate the confidence NASA places in Blue Origin," the company's program manager, Rob Meyerson, said in an emailed statement.

Sierra Nevada Corp.

Sierra Nevada Corp.: Sierra Nevada received $20 million during CCDev1 and is getting $80 million in CCDev2 to continue development of its Dream Chaser space plane, which is based on the HL-20 lifting-body design that NASA pioneered back in the 1980s. The concept was revived by high-tech entrepreneur Jim Benson at SpaceDev and inherited by Sierra Nevada when it acquired SpaceDev in 2008. (Benson had left SpaceDev two years earlier and came up with a different spaceship concept, but he passed away in 2008 before he could get very far with the idea.)

Sierra Nevada's top corporate officers are in the public eye far less than Jeff Bezos. After all, Bezos is still the head of a publicly traded company, but CEO Fatih Ozmen and his wife, company president and chief financial officer Eren Ozmen don't have much reason to go public. Three years ago, a story about Sierra Nevada in the Las Vegas Sun called Fatih Ozmen a "mystery man."

The Ozmens started out as employees at Sierra Nevada and acquired the Nevada-based company in 1994. Since then, Sierra Nevada has grown into a big-time defense contractor with 29 locations in 15 states. Inc. magazine listed its 2009 revenue at just under a billion dollars.

Sierra Nevada's website lists numerous awards, including recognition as "the top woman-owned company demonstrating excellence in applying innovative IT solutions to the federal government." But the company has also experienced the occasional hiccup, such as recent questions over the development of an imaging pod for the Air Force, called Gorgon Stare.

The company's agreement with NASA lists 11 partners, including Boeing, United Launch Alliance, United Space Alliance, Aerojet, Draper Lab, NASA's Langley Research Center, AdamWorks, SAS, the University of Colorado, the U.S. component of Canada's MDA robotics company and Virgin Galactic (which is working with Sierra Nevada on "global marketing, sales and commercial operation" of the orbital Dream Chaser).

SpaceX

An artist's conception shows SpaceX's Draco thruster engines firing to separate the Dragon spacecraft from the Falcon 9 second stage. Side-mounted thrusters could be used as a launch abort system and landing system.

SpaceX: This California-based company, founded by high-tech entrepreneur Elon Musk in 2002, has notched a surprising number of space successes lately, including last December's launch-to-splashdown test of its Falcon 9 rocket and Dragon cargo capsule. NASA is supporting the development of the Falcon-Dragon system with $278 million under a separate program for cargo craft development, known as Commercial Orbital Transport Services or COTS. If SpaceX hits its marks, it will be in line for $1.6 billion worth of NASA contracts to deliver cargo to the International Space Station.

Musk has said it would take $1 billion and three years of work to adapt the Falcon-Dragon system to carry crew, primarily because of the expense of developing an emergency launch abort system. This week, he said the $75 million in CCDev2 money would put SpaceX on track to meet that schedule.

"The award will accelerate our efforts to develop the next generation of rockets and spacecraft for human transportation," Musk said in a statement. "With NASA's support, SpaceX will be ready to fly its first manned mission in 2014."

Musk has made no secret of his long-term goal: to open the way for colonizing Mars and turn humanity into a multiplanet species. This week's statement referred slyly to those ambitions by noting that SpaceX's thruster system would "provide the capability for Dragon to land almost anywhere on Earth or another planet with pinpoint accuracy, overcoming the limitation of a winged architecture that works only in Earth's atmosphere."

A couple of years ago, Musk said that he invested $100 million of his fortune in SpaceX — but there have been more recent indications that the spigot has been turned down on his personal cash flow. SpaceX recently reported raising $50 million in additional funds, and Musk said an initial public offering may take place next year. Last year, there were a flurry of reports about Musk's financial straits, which led him to discuss the situation candidly in the Huffington Post.

SpaceX's agreement with NASA says the $75 million would accelerate crew-transport development by 50 percent compared to an internally funded baseline. So what does that say about SpaceX's investment? That figure is blacked out in the agreement posted online, but if time is money, that might imply SpaceX is bringing $75 million of its own to the project. The section listing SpaceX's partners and institutional investors is also blacked out, but the company notes that it works in "close collaboration with four NASA centers and eight leading aerospace companies."

Boeing

Boeing's CST-100 craft approaches the International Space Station in an artist's concept.

The Boeing Co.: This aerospace giant is something of an outlier. It's publicly traded, and has been involved in the U.S. space effort for decades. Among other things, Boeing served as the prime contractor for construction of the International Space Station. Billings' knock against Boeing was that with $3.3 billion in profit for 2010, the company didn't need a government "subsidy" for its spaceship-building operation.

However, Boeing's John Elbon repeatedly said in the run-up to the CCDev2 announcement that NASA had to serve as the anchor customer for the company's proposed CST-100 crew capsule. Without NASA support, the financial underpinnings of the project just didn't stand up. The $92.3 million in CCDev2 money, added to the $18 million from CCDev1, will keep Boeing on track to have the capsule ready for flight by 2015.

"By the end of CCDev2, our design will be firmed up and we'll have it synced up with NASA requirements so we understand our vehicle will meet those requirements," Boeing's John Elbon told reporters.

Boeing's go-ahead is also good news for Robert Bigelow, whose aerospace company has already put up two inflatable test modules into orbit on Russian spacecraft. Bigelow Aerospace is hoping that the CST-100 — perhaps launched on an Atlas 5, Delta 4 or Falcon 9 — can bring paying passengers to its future private-sector space stations as well as to the government-supported International Space Station.

In addition to Bigelow, Boeing's agreement with NASA lists Pratt & Whitney Rocketdyne, Airborne Systems, ILC Dover, Spincraft, XCOR Aerospace, United Space Alliance and ARES Corp. as teammates and investors. Boeing also notes its agreements with Bigelow, Space Adventures and an additional blacked-out entity "to increase market growth."

Orbital Sciences Corp.

Orbital Sciences' Prometheus space plane, shown in this artist's conception, was one of the proposals that NASA passed up. Orbital is now reportedly planning to mothball the concept.

What separated the winners and losers: NASA has now released the full list of companies proposing CCDev2 spaceship projects, plus short rundowns on why particular proposals were chosen or eliminated. It's fascinating reading for space geeks.

The also-rans included alphaSpaces, Andrews Space, ATK Aerospace Systems, Excalibur Almaz, ILC Dover, Innovative Space Propulsion Systems, KT Engineering, Oceaneering International, Orbital Outfitters, Orbital Sciences Corp., Orbital Space Transport, Paragon Space Development Corp., PlanetSpace, Spacedesign Corp., TGV Rockets, Transformational Space Corp. (a.k.a. t/Space), United Launch Alliance and United Space Alliance.

Philip McAlister, acting director of NASA Headquarters' Commercial Spaceflight Development program, said Boeing and SpaceX were clear standouts from the rest of the pack. "They were the only ones to receive 'very high' confidence ratings, which I consider significant," he wrote.

ATK, Excalibur Almaz and United Launch Alliance were among the finalists, but McAlister said Excalibur Almaz was eliminated due to low ratings, especially on business considerations. He opted not to go with ATK and United Launch Alliance in part because of their lack of linkage to a crew-carrying vehicle. Those two companies were proposing only to build launch vehicles, and McAlister put somewhat less weight on that side of the equation.

"Within the U.S. industrial base, there is considerable launch vehicle development expertise, as many companies have successfully developed new launch vehicles over the last few decades," he explained. "In contrast, no U.S. company has successfully developed a crew-carrying spacecraft in over 30 years."

In other words, not since the space shuttle ... unless you count the private-sector SpaceShipOne rocket plane, which made three suborbital space trips in 2004. 

Lockheed Martin

Lockheed Martin's Space Operations Simulation Center in Colorado can simulate on-orbit docking maneuvers using mockups of the Orion spce capsule, left, and the International Space Station.

So what's next? The CCDev2 covers the development timeline through May 2012, but NASA is looking for another $850 million to cover the third phase of the program, CCDev3. Being a CCDev2 winner doesn't guarantee that you'll get CCDev3 funding, and it's possible that a company not receiving money in one phase of the program could be funded for a future phase. For example, SpaceX didn't receive any funding in CCDev1 but was awarded $75 million in CCDev2.

The agreements with NASA spell out milestones that must be met in order to receive incremental payments. It's not guaranteed that all the companies will meet all the milestones. For example, Rocketplane Kistler was awarded up to $207 million from COTS, NASA's cargo spacecraft development program, but the company couldn't reach its investment target and was cut off after receiving $32.1 million for hitting earlier milestones.

If the CCDev process is successful, NASA should be able to choose from new U.S.-built spaceships for launching astronauts to the International Space Station in the 2014-2015 time frame. In the meantime, the space agency will have to rely on Russia's Soyuz spacecraft for crew transport. NASA expects to begin sending cargo up to the International Space Station on remote-controlled craft provided by SpaceX and Orbital Sciences Corp. as early as next year.

Separately, NASA is also funding Lockheed Martin's work of the Orion crew capsule, which is currently envisioned as a NASA-operated emergency crew escape vehicle. Such capsules would be launched to the space station without a crew, thus minimizing the flight risk.

The Orion may well turn into the multipurpose crew vehicle that Congress wants NASA to develop for trips beyond Earth orbit. Congress has set aside $1.2 billion in the current fiscal year for the Orion-based crew vehicle, plus $1.8 billion for a heavy-lift rocket capable of putting 130 tons of payload into orbit. Lawmakers want to see that mission accomplished by 2016, but NASA isn't sure the job can be done. 

Even if the beyond-Earth space transport system is ready by 2016, NASA is expected to use commercial transports to get astronauts to and from the space station. Using a heavy-lifter to send astronauts to low Earth orbit would be like using a semi to get from one end of town to the other. It's better to call a taxi ... which is exactly what NASA plans to do once its commercial "space taxis" are ready to fly.
