A private space company offering room on inflatable space habitats for research has found a robust international market, with eager clients signing up from space agencies, government departments and research groups.

Space entrepreneur Robert Bigelow, chief of Bigelow Aerospace, has been busy marketing his private space modules, an outreach effort leading to six deals being signed with clients this year.

The deals, in the form of memorandums of understanding, involve Japan, the Netherlands, Singapore, Sweden, Australia and the United Kingdom.

"These are countries that do not want to be hostage to just what the International Space Station may or may not deliver," Bigelow told in an exclusive interview. [ Bigelow Aerospace plans private moon bases.]

Bigelow founded Bigelow Aerospace in 1999, headquartered in Las Vegas, drawing upon his construction, real estate, and hotel savvy to forge the use of expandable space structures. To date, he has spent more than $200 million to hammer out his business plan for space.

Steel in the air

Some of that private cash was spent to hurl two of his firm's prototype expandable space modules into orbit. The company's Genesis 1 and Genesis 2 test modules, lofted in July 2006 and in June 2007, served as forerunners to ever-larger and human-rated space structures.

More recently, some $20 million of Bigelows cash has flowed into a sprawling, 185,000 square-foot expansion to his North Las Vegas facilities, a building that enables the churning out of bigger space habitats.

"That expansion is currently under way. We broke ground a few months ago. We've got a lot of steel in the air," Bigelow said. But more newsworthy, he said, is the signing of memorandums of understanding to make use of the companys expandable space structures.

"I'm also in the middle of developing a new client leasing guide that will be available toward the end of the year. It will have new and exciting pricing opportunities that are very dramatic," Bigelow said."We want to open up the window and doors for a lot of participation for folks that need to spend less."

Robust and global

A question that continues to float through the halls of NASA and the Congress: Is there a commercial market for utilizing space?

"Weve got a very certain and loud answer to that. Not only is there a commercial market, but it's a one that's robust and global," said Michael Gold, director of Washington, D.C., operations and business growth for Bigelow Aerospace.

The memorandums have been signed with what Gold said the firm terms as "sovereign clients" the result of a relatively modest effort to pulse "international astronautics opportunities" with countries large and small.

Bigelow said what they have found is a hunger by clients to do activities in space far beyond just microgravity experimentation.

"That is what this new leasing guide is going to expose," Bigelow said. "Its encouraging to see the enthusiasm. They all have different reasons, different ways in which they see using our facilities what I call 'dynamic assets' in the new leasing guide to benefit them. It can change the face of a nation."

Gold said that some $100 billion has been spent on the International Space Station.

"All that money to create an amazing laboratory environment in space but when it comes to actually doing something with it, whats being spent on utilization is relatively paltry," Gold emphasized. "Its like purchasing a Lamborghini and then spending five dollars on gas."

While countries in Asia and Europe take commercial advantage of space, "my fear is that this could become yet another extremely lucrative economic opportunity that is engendered here and then shipped overseas," Gold cautioned. "The U.S. Congress should spend less time questioning the business case of the commercial market. They need to spend more time trying to figure out how to grow that market and ensure that it happens here in the United States."

Tried and true

Still, while there is "palpable enthusiasm," according to Gold, by clients to use Bigelow space facilities, getting customers back and forth to low-Earth orbit remains to be solved.

Boeing and Bigelow Aerospace have been working together on access to a Bigelow-provided Orbital Space Complex, making use of Boeing's CST-100 capsule being pursued under NASAs Commercial Crew Development (CCDev) program.

Gold underscored the "great potential" of the Atlas 5 booster.

"We have much more confidence in regards to the crew transportation solution since there is, arguably, no system safer, more reliable and more cost-effective than leveraging the tried and true Atlas 5 with a capsule built by Boeing on top of it," he said. "It has a track record. It exists. Thats a message that has resonated quite well with the international clients."

There has been discussion, Gold said, that cost savings and safety are mutually exclusive.

"The Atlas 5 is an example of how those two actually go hand in hand. That rockets flight heritage will create the safety that we demand and our customers require," he concluded.

Explainer: Ten high-profile players in the commercial space race

  • Image: Obama at KSC

    US President Barack Obama walks past a main engine of a shuttle as he arrives to speak on the new course the administration is charting for NASA and the future of US leadership in human space flight at the Kennedy Space Center in Cape Canaveral, Florida, on April 15, 2010.

    When NASA's space shuttle fleet retires in 2011, the space agency will have to rely on Russian spacecraft and the private sector to taxi cargo and humans to and from the International Space Station, even as it turns its focus to the technologies required to send humans beyond low-Earth orbit.

    President Barack Obama views the policy as a boost to the nascent commercial spaceflight industry, where competition is already heating up to supply the taxi services. Some companies are also talking about offering out-of-this-world rides for researchers as well as tourists with deep pockets and a serious case of star lust. Click ahead to check out 10 of the top players in the race to commercialize space.

  • Space Exploration Technologies

    SpaceX's Falcon 9 rises from its launch pad at Cape Canaveral Air Force Station in Florida on Friday, sending a test capsule into orbit.

    PayPal co-founder Elon Musk has already signed up NASA as a marquee account for his high-flying venture, Space Exploration Technologies, also known as SpaceX. The government has a $1.6 billion contract with the Hawthorne, Calif., company to provide unmanned cargo deliveries to the International Space Station starting in 2011 with its Falcon 9 rocket and Dragon capsule.

    This image shows the successful test launch of the Falcon 9 rocket on June 4. The rocket will eventually carry the Dragon to orbit. If all goes according to plan, astronauts may get a lift as well, starting in 2013. SpaceX has also secured contracts to launch next-generation satellites for the telecommunications company Iridium.

  • Orbital Sciences

    Another NASA contract — this one worth a reported $1.9 billion — is in the bag at Virginia-based Orbital Sciences, which is planning to supply the International Space Station with its unmanned Cygnus spacecraft, shown here in an artist’s rendering. A newly-developed Taurus 2 rocket will ferry the cargo ship to space. If the opportunity presents itself, the company may advance plans to ferry humans to orbit as well.

  • Boeing

    Boeing is hard at work on the research and development of a new space capsule aimed at flying people to the International Space Station.

    Boeing, the aerospace giant, has unveiled plans to flesh out designs and build a new capsule-based spaceship called the CST-100, which will take cargo and passengers to the International Space Station. The development push comes thanks to an $18 million NASA grant.

    The Apollo-like capsule will carry a crew of seven and be designed to launch on a variety of rockets, including the Atlas and Delta rockets operated by the Boeing-Lockheed Martin joint venture known as the United Launch Alliance, as well as SpaceX's Falcon. Extra seats may be made available for paying passengers through a marketing arrangement with Space Adventures.

  • Masten Space Systems

    While big NASA contracts have already gone to big names in the commercial space industry, lesser-known Masten Space Systems is in the race to pick up taxi fares to the International Space Station as well.

    The company won a $1 million lunar challenge prize with the Xoie spacecraft shown here. It is now working on a next-generation vehicle based on the vertical-takeoff-and-landing design to ferry cargo. NASA funding will go toward four test flights of the spacecraft, called Xaero.

  • Sierra Nevada Corporation

    The reusable Dream Chaser space plane, under development by Sierra Nevada Corp. subsidiary SpaceDev , has a look and feel reminiscent of a mini-space shuttle. Like NASA spacecraft, a rocket lifts the space plane up — and at the end of its mission, the plane lands on a runway.

    In fact, the transportation system is based on NASA technology, and the company recently received $20 million from the space agency to continue the plane's development. A full-scale mockup of the plane is shown in this file photo from its unveiling in 2006.

  • Bigelow Aerospace

    Entrepreneur Robert Bigelow padded his bank account by building a hotel chain, Budget Suites of America. His latest pioneering venture, Bigelow Aerospace, is aimed at building affordable habitats in space.

    Two prototype inflatable capsules have already been launched, and plans are in the works to put the more expansive Sundancer space station, shown here in an artist's conception, in orbit by 2015.

    In this case, the overnight guests may include national space agencies as well as private-sector researchers and thrill-seeking tourists. Other players in the commercial space sector would taxi guests to and from the puffy digs.

  • Blue Origin

    Blue Origin founder Jeff Bezos, who amassed a fortune selling the printed word online, has few words to share about Blue Origin, his commercial space venture to fly a vertical launch and landing rocket to suborbital space.

    This much is known: A demonstration vehicle called Goddard, shown here in a file photo, successfully took off and landed in 2006 from the company's private spaceport in west Texas. It's not yet known when the company's commercial vehicle will be ready for a public unveiling.

    A bit more info: NASA recently awarded the company $3.7 million of a $50 million pie that it says is for the "development of system concepts, key technologies, and capabilities that could ultimately be used in commercial crew human space transportation systems." Blue Origin is concentrating on the development of a launch escape system that could push a NASA capsule to safety in case of emergency.

  • Virgin Galactic

    The Virgin Galactic suborbital spaceliner SpaceShipTwo makes its first crewed flight on July 15, 2010 over the Mojave Desert in California.

    Space enthusiasts with $200,000 to burn can book a ticket to ride to outer space with Virgin Galactic on the SpaceShipTwo spacecraft. The plane, meant for tourism as well as research, will haul six passengers and two pilots on suborbital flights that pop into outer space for a few minutes before returning to Earth.

    The aircraft was designed by aerospace engineer Burt Rutan and colleagues at Scaled Composites. Test flights of the spacecraft, which launches from the WhiteKnightTwo mothership, are under way. Ticketholders will get their opportunity to ride once all systems are a go.

  • Armadillo Aerospace

    Would-be space tourists who balk at the price tag for a ride on Virgin Galactic's SpaceShipTwo might consider another option in the offing: $102,000 for a seat on Texas-based Armadillo Aerospace's vertical takeoff and landing vehicle.

    The spacecraft, shown in this artist's conception, will rocket passengers into outer space for about five minutes of weightlessness and 360-degree views. Tickets can be booked through Space Adventures, the same company that has arranged rides to the International Space Station for the super-wealthy.

  • XCOR Aerospace

    Yet another option for the space tourist is a $95,000 trip up to the inky blackness at the edge of space in XCOR's Lynx rocketship. The spacecraft, which has room for just one pilot and one passenger riding shotgun, takes off horizontally from a runway and climbs steeply to 200,000 feet, where views abound of planet Earth and the stars. Advance reservations for the hour-long trip can be booked through space tourism company RocketShipTours. An artist's rendering of the rocketship is seen here.
