Updates will be here now.

Life support seems to be progressing....

Bigelow Tests Life Support System

WASHINGTON — Bigelow Aerospace completed an initial closed-loop test in March of a prototype environmental control and life support (ECLS) system designed to support extended crew stays inside the inflatable habitats the company is building to provide research facilities and hotel accommodations in space.

The March 31 demonstration was conducted inside the company’s North Las Vegas headquarters in a newly constructed test chamber, according to Eric Haakonstad, Bigelow Aerospace chief engineer. He said the test involved locking three Bigelow engineers inside the 180-cubic-meter structure for about eight hours, during which they performed a variety of tasks that demonstrated the ECLS system’s ability to control temperature, humidity, pressure, oxygen content and the removal of carbon dioxide and trace-gas contaminants from the environment.

Haakonstad said the initial checkout of the test facility is the first of many demos planned over the next year to simulate and test ECLS systems in support of long-duration crew stays in orbit. He said within the next couple of months Bigelow Aerospace plans to conduct a 30-hour demonstration of the ECLS system followed by another lasting up to a week.

He said both the ECLS system and its test chamber were built in-house, giving the company more control over system development.

Haakonstad said Bigelow’s ECLS design incorporates lessons learned from systems used aboard platforms including the international space station, the Mir space station, the space shuttle and, to a lesser extent, the Orion crew capsule currently under development by NASA.

“We’re not reinventing the wheel here,” Haakonstad said. “All we’re trying to do is take the technology development that our tax dollars through NASA have developed and package them into a more producible form factor. We’re not trying to be cutting edge in terms of technology; we are trying to be cutting edge in terms of affordability and availability and ruggedness.”

However, unlike ECLS systems designed for short-term trips between Earth and the space station, Bigelow’s ECLS system is designed to support long-duration missions on orbit.

A Bigelow Aerospace primer - 2 Nevada news stories from a few months back that have a lot of info about their business plan etc.

About 10:55 long.

To be totally honest I'd be more excited if they turned the idea of the inflatable station into a moon base or something awesome like that; if you made a facility huge enough on the moon it should be self sustainable. Are there any plans of using the idea on a moon base?

Absolutely!! Bigelow has a whole set of patents for a landable base complex to be assembled at EML-1, a gravitational equilibrium point between Earth & Moon that's a perfect place for space docks, fuel depots etc. More Bigeliw info & pics in this thread -

he deserves these honors, i'd name a few characters/ships after him were i a notable sci fi writer/hollywood bigwig...

and yes, Doc has been telling us about their moon base plans for a while now. i really hope they become reality by the end of this decade.

All at Google Patents - search for "Robert T Bigelow." these are the applications.

When looking at the base remember that while the hab walls are expandable & flexible at first, they are rigid after deployment. The habs also have metal cores and bulkheads at either end, making the whole structure very strong. Docking them to the solid metal hub/propulsion buses, which use the same attachment used at ISS, makes for a very solid structure.

Basic satellite bus (habitat)....

Impact shield....

Landable base....

Emergency safe haven....

Biomass disposal....

what would be the cost of a moon base that can support let's say 50 people year-round? are there any such estimates based on Bigelow designs?

Bigelow has estimated each BA-330 module would cost ~$100M. As to the cost of the propulsion bus/hubs - that's pure guesswork, but guess high at the same as a module and you have a (probably high) cost of ~$1B for the base plus launch costs of $125M per Falcon Heavy which could well do two-fer launches.

Now consider that NASA spent ~$40B on the Constellation program over the last 6 years and have nothing to show but a cancelled program and an Orion spacecraft that may never fly, especially if Dragon works as advertised.

jesus, we could have had an entire city up there now for 40 billion...what were they thinking? or is this the true, ugly face of corruption? thanks for the figures, that's quite economical, really. i have no idea why we're not doing it then. you want to tell me we could go to Mars and establish an outpost there for like $20 billion or so? and we're still not doing it?

If we had used $0.02 worth of common sense we could have been on Mars 20+ years ago. More numbers for you -

US cost of ISS: $100 billion
2x larger volume than ISS Bigelow station: less than $1 billion

Shuttle flights: $1.5 billion, each
Falcon 9 flights: $56 million
Cost of Dragon fligyr: $133 million
Falcon Heavy flights : $80 - $125 million (2x the cargo of shuttle)

and a few examples of what $600 million pays for -

Ares I-X test flight: not light hardware. It only tested the shape & failed
Launch tower for Ares 1-X
What Congress spent on Constellation after it was cancelled
TOTAL development cost of Dragon & Falcon 9

then how do you account for this kind of gross negligence?
