Wonder exactly what is in that Aerojet contract?
For a better sense of scale, here's Lori Garver on a recent visit to Bigelow facilities...http://www.flickr.com/photos/nasahqphoto/5417051168/

Remember that these will be used in zero-g so any crew member that is not firmly attached to a surface and cannot *reach* some other surface is effectively stuck in midair
There's not much new here & I'm sick of hearing the derogatory tag "Space Hotel" but it's an excellent article.

The main impression is that there is so much technology to be developed before any of this can be realized. Just the fourth illustration of the assembly shows a "Supplemental power bus and docking node" with five docking/berthing hatches heading for a rendezvous with the occupied Sundancer/CST-100. Rigid, steerable solar arrays, (that aren't steered in any of the pictures and pretty darned small), thermal radiators,... The expandable/inflatable structures, as useful as they may be, are just the tip of the iceberg, so to speak.
Someone showed me a copy of a very large (230 mm by 350 mm) brochure from Bigelow titled "JUST THE BEGINNING 2011". It has illustrations of the step by step assembly of a three module space station with three CST-100 capsules and three crews, starting with the launch on some purposely mash-up rocket. There are illustrations of a three unit and four propulsive support units at "L1", landing, and sitting on the Moon and even a seven unit "Lunar Depot Ares at Lagrangian 1 Point".There are many comparison illustrations of the enormous available volume when compared to "ISS Destiny Module" / "Traditional Aluminum Can Design". One reason they are so roomy is that Destiny is 80% filled with science racks and their supporting services, while the Bigelow modules are completely empty except for the people floating inside.
There is also an eight page, effusive statement by Robert Bigelow on why leasing a space station is a necessity for any country that wants to project power and prestige. "Who knows, the very key to levitation (a sort of Holy Grail in the space world) may be waiting to be discovered in that strange environment of microgravity." "We have already linked the connection in power that can exist through enhanced national image, wealth, and influence. " One of his prospective "Sovereign Nation Consortia" customers is "Egypt, Morocco, Tunisia, and Algeria". This was probably written before those particular countries became, let's say, distracted with personal issues unrelated to space.The main impression is that there is so much technology to be developed before any of this can be realized.

For a nation wanting to be seen as independent of western governments (India, Pakistan, South Africa, Brazil, Indonesia, etc) a free market option is not just more economical, but politically more viable.

We don't have a space program - a government one anyway. I can't see the African National Congress sending people into space when there's rampant poverty in our own country.Nope, in this country you have to work for it. You have to make billions, go to the US, naturalise, and start up your own space company.

The Bigelow modules are launched uninflated, but with a core that is simply packed with racks of gear, at least as much as a standard ISS module if not more so. The Bigelow module makes its room thereafter from inflation, but the core retains all the equipment it was launched with.Solar panels dont need to steer on a time frame that fits within a simulation video.

And there is no "simulation video", just unsophosticated illustrations. The point is that they don't have even solid models that can be adjusted. The solar panels are all shown in some initial orientation, even when that does not make sense.
Lets not forget that they have launched and are currently operating two subscale demonstrators using the depicted architecture.It could be that they are just choosing not to depict it because it is assumed. Or they may have a different solution that they choose not to share. Either way, they have actual hardware flying and that says something very important about their commitment.
