Bigelow Aerospace's Genesis-1 Performing Well

LAS VEGAS, Nevada – It’s a new form of “high stakes” from this gambling city—a privately-funded and designed expandable space module now circles the Earth.

Bigelow Aerospace here is the odds-on-favorite to create a low-cost, low Earth orbit space complex that is accessible to the commercial sector. That goal has been bolstered by the success of their Genesis-1 expandable module, lofted into space July 12 courtesy of a converted Cold War rocket—the Ukrainian-built Dnepr booster provided by ISC Kosmotras.

Even as Genesis-1 circles the Earth, work is already underway for a Genesis-2 launch before year’s end. That flight is expected to lead six months later to lofting a larger, more sophisticated module called Galaxy.

Twice the size of the Genesis-1 now in space, Galaxy will offer 23 cubic meters of interior volume, carry higher-fidelity systems, and is more in a direct path to Bigelow’s full-scale kind of thinking in terms of ever-larger modules.

Doubting Thomas

“I’m on Cloud 9 over this success,” said space entrepreneur, Robert Bigelow, founder and president of Bigelow Aerospace during a press conference held yesterday on the firm’s sprawling 50-acre, ultra-secure facility.

So far, some $75 million has been spent on the company’s progress. Bigelow said they are preparing a volley of flights to throw at the problem of expandable module development and use, not only for low Earth orbit, but also for utilization on the Moon and Mars.

As Genesis-1 flew overhead during the press conference, Bigelow told SPACE.com that he was the Doubting Thomas of the company—others on the project were more optimistic.

“Secretly, I felt good about our people, our team … and I knew that our contractors were good. Yes, you kind of have to prepare yourself maybe for failure. But deep inside I thought there was a chance that we were going to make it,” Bigelow explained. “We are not under any illusion that we’ll have this kind of success each and every time … I don’t think any of us would buy off on that.”

Long lifetime

Post-launch data of Genesis-1 has now been analyzed, showing that the module has 7 to 13 years of lifetime in orbit, said Eric Haakonstad, Genesis program manager. “We are optimistic that we’re going to have quite a long time to collect, not just initial performance data, but long-term data as well,” he told SPACE.com.

Haakonstad said the robustness of the Genesis-1 systems are to be closely watched—internal and external power hardware, communications systems, as well as the integrity of the module’s hull structure.

“We want to make sure that it just doesn’t just work for the first month, the first week … but it works two years, three years from now, reliably,” Haakonstad noted. Typical of space systems, he added, the weakest link is the power system “and that’s no different here.”

“What we’re trying to do with this first spacecraft is draw attention to our second spacecraft,” Haakonstad explained. The public can become directly involved through a “Fly Your Stuff” program (http://www.bigelowaerospace.com/fly_stuff/) where personal mementoes, photographs, or other items will be flown for a modest fee onboard the Genesis-2.

As an Earth orbiting module that will circle for years—objects flown are on a one-way trip.

Slow tumble

Here at the Bigelow Aerospace control center, huge screens of data and images from Genesis-1 are displayed. To date, some 500 images have been channeled down from the orbiting spacecraft.

There is limited contact with Genesis-1—two passes a day that are relatively short. Ground controllers monitor the overall health of the vessel outfitted with its eight company-made solar wings deployed, said Mark Pierson, Bigelow Aerospace manager for vehicle integration and testing.

Once in orbit, Genesis-1 took all of 10 minutes to successfully expand to 8 feet (2.4 meters) in diameter, Pierson told SPACE.com. “The systems are at 100 percent. Everything is working. It’s awesome and we’re thrilled.”

The Genesis-1 is in a slow tumble as it orbits Earth.

That has complicated the snagging of downlink imagery and other data. That tumble issue is expected to dampen out in few weeks, enabling ground operators to get onboard antennas better pointed to upgrade the download of information, as well as fine-tune internal and external cameras, Pierson said.

Frequent launch, low-risk approach

Data-gathering stations in both Hawaii and Alaska are coming online in the near future. They will augment the ability of ground control to monitor Bigelow Aerospace orbiting modules.

Genesis-1 is outfitted with 6 interior and 7 exterior cameras. Genesis-2 will have somewhere on the neighborhood of 18 cameras. Galaxy is to utilize 32 cameras, Bigelow said. Also in the works is building a mega-control center and public viewing balcony that can support 300 onlookers, he told SPACE.com, to keep vigil on the firm’s multiple modules as they fly around Earth.

“The amount of success on the first launch was probably the biggest surprise,” admitted

Haakonstad. Work is underway on Genesis-2 with integration of its various components slated within the next couple of weeks, he said.

“We’re trying to take a frequent launch … low-risk approach … not putting all of our eggs into one basket,” Haakonstad said.

I was interested in the comment that the module is slowly tumbling. If that's so I'm thinking the power supply might be in jeopardy if they are unable to keep the solar array aligned.

[KevinDavis]

That is only a minor glitch.. Once there are people, I think that problem could be fixed..

[saganite]

There won't be any people on this one. The glitch will have to be corrected from the ground. I don't think there are any onboard thrusters to stabilize it so the comment that the slow tumble will work itself out leaves me baffled.

[KevinDavis]

Plus this is only a test....

[Lokibob]

Absolutely a small thing.

This has sent me way back in time at WSMR. We were assigned to track one of the first weather satellites. We had to compute the times and az angle of the pass, the angle of the antenna each minute of the orbit over WSMR, and when the pictures would be taken and transmit times. BTW, all this had to be done by hand (late 60's, no computers).

Then, 10 mins before the pass, we ran to the roof, fired up the equipment, pointed the antenna in the right direction, and recorded the picture the satellite had just taken. We put it on Polaroid film (BnW), and put the goop on it to preserve it, and brought it to the forecasters, who oohhhed and ahhhhed over it.

Then it was wait another 90 mins for the next pass. I'll bet we burned up 10,000 rolls of Polaroid film, cause everybody had to have a copy.

Boy do I wish I had kept some copies for myself....Bob

I still think Bigelow is a flake.

I was my hope that we could keep space free of Bigelows.

Sadly enough, the feds are nevertheless stifling entrepreneurial space:

Senate Report 109-280 Departments of Commerce and Justice, Science and Related Agencies Appropriations Bill 2007

STATUS REPORT
Date Released: Friday, July 14, 2006
Source: Senate Appropriations Committee

HIGHLY ALARMING EXCERPT: "The Committee does not provide any funding in fiscal year 2007 for the Centennial Challenges program. Funding provided in previous fiscal years for this program is sufficient for NASA to run a prize based competition, as well as to verify that NASA will see tangential benefits from running such a program. Providing additional funds to a program based on prizes only creates a pot of unused funds while other aspects of NASA's mission are being cut or delayed due to a lack of funds."

I still think Bigelow is a flake.

He is, but he's already been very successful in the business world where there are lots of flakes in the entrepreneurial category.

[Hazcat]

What makes you call him a flake? He may talk dreams but he is doing it.

[Moonman62]

Just from some of the things I've read, but he's the good kind of flake. He's been successful before and so far he's been successful in his new venture.

[Hazcat]

OK, That's what I meant by the "dreamer" part of my post. It usually take a guy with 'strange' ideas to start things happening (and of course good engineers.)

[Moonman62]

I read that he always hired the best people and used the best materials. And he was in the low tech apartment and hotel business. Compare that to some of the "non-flakey" people who think that cheap, exploitable labor is the growth engine of our economy.
