IMHO, it would be good if you gave a sentence or two indicating what the big news is instead of just posting a link....Boris_Badenov":38x0jzcm said:
Play on words or something like that there expanding and buildign a HUGE new facilityMeteorWayne":21k5ro8r said:I admit I don't understand what makes this HUGE news....I don't see anything different than the plan they've had all along. What makes it huge?
docm":37h9fqvu said:No. Hypergolic thrusters and orbital maneuvering engines. IIRC Aerojet is making them. VASIMR would be used for tugs and BLEO.
The 'small' test engine needs about 20KW to operate, which even the huge ISS can't spare. In fact, this 'small' engine needs quite large solar panels, so it really is not small anymore. VASIMR counts in tons, not kilos :idea:The small solar powered VASIMR would be an excellant choice for re-boosting the station complex.
VASIMR is still in testing though. Hypergolics are available, off the shelf, right now.shuttle_guy":10k1cnss said:docm":10k1cnss said:No. Hypergolic thrusters and orbital maneuvering engines. IIRC Aerojet is making them. VASIMR would be used for tugs and BLEO.
I disagree as for as re-boost is concerned. The small solar powered VASIMR would be an excellant choice for re-boosting the station complex. I refer to the first VASIMR engine which is planned to be tested on the ISS.
Yeah it does , the only thing keeping me from dropping where I live now is my kids are here and it's in the heat of Vegas , not really somewhere I want to live . Granted it's only a 4.5 hour drive from where I am to Vegas so the kid things not that bad but still , it's Vegas . Wish they had some manufacturing in SanDiego , although I did get my boss to send in our info as a sub-contractor so we should be seeing some quotes soon hopefully . I will be in Vegas in a few months since my daughter's getting married there in october and while I am there I plan to pay a visit to Bigelow to see what's seeable . I'll take some pictures and post em here when I do .nimbus":3pr06pcy said:

Boeing and Bigelow Aerospace are teaming up to build a commercial space station system, with a 2015 target for a fully operational station in low Earth orbit (LEO), the companies announced on the first day of the show.
The aggressive schedule - with assembly in 2014 and testing to include an uncrewed trip to the station - is contingent upon the US Congress coming through with funding for NASA's proposed Commercial Crew Development (CCDev) Space Act Agreement programme this fall.
"We need the funding. The money that NASA has proposed closes the business case. Without that, we would have a difficult time," says Brewster Shaw, former astronaut and vice-president and general manager of Boeing's space exploration division.
The plan, crafted largely by Robert Bigelow, the US hotelier turned aerospace company owner, is to build a modular 690m3 (24,000ft3) space station in LEO, starting a second, larger station within years for the first. The first will consist of four modules, four habitats and one propulsion and docking unit.
The Obama Administration, in a departure from previous US space policy, has proposed more emphasis on commercial space, with companies taking on major research and development and creating new launch capabilities, leaving NASA to focus on planetary exploration. Funding, however, has yet to materialise, with many in Congress concerned that the commercialisation of space is too dangerous an undertaking to support at this time.
Plans seem to have matured. Instead of a 3 module station, it's been upped to 4 for the CSS Skywalker.EarthlingX":1dauobkg said:The plan, crafted largely by Robert Bigelow, the US hotelier turned aerospace company owner, is to build a modular 690m3 (24,000ft3) space station in LEO, starting a second, larger station within years for the first.

OOO nice. Its crazy to realize how big those moduals could be. How big could one launched by a Falcon XX be :twisted:docm":1thtnok2 said:Bigelow Aerospace's inflatable modules will use a new take on recycling - turning the crews sweat, urine and waste-water into fuel for the modules Forward Propulsion System using power from its solar panels. Also an advantage is that this allows their stations to perform attitude control maneuvers without having the usual toxic propellants on board.
The hydrogen/oxygen thrusters were developed by Orion Propulsion, which is now owned by major defense contractor Dynetics, Inc.
