AckSed Posted March 8 Share Posted March 8 Very glad something like this is actually being built. Looking at the actual specifications, this thing is wider than Skylab. It also anticipates StarShip if "Capacity for 50+ tons of interior outfitting" is any indication. I can't help but imagine this coupled to the Spacecoach concept: simple spacecraft with water walls for radiation protection, clustered electrical water-propelled thrusters for travelling between Luna, Mars and Earth, and partially-open-loop life-support. Hydrogen peroxide can be generated onboard to fuel the attitude control thrusters. You'd need a powerful solar array, but that's not too onerous.

JoeSchmuckatelli Posted March 8 Share Posted March 8 Am I wrong to be leery of all the 'Space Station Startups'? Even if SS gets up and flying this year or next... Is there a demand for this? Aside from the Billionaire Lookatme crowd - I'd think there would have to be some kind of industrial /commercial need (beyond hostelry) to make even one of these viable.

Yep, this is what worries me too. Hard to say "if you build it, they will come" when people can't just drive or walk to the thing you're building.

Should someone get access to research from university / NASA indicating that some kind of LEO manufacturing could be profitable - the initial size of any facility isn't going to scale well. 7m sounds huge for a human spaceflight container - but for some kind of factory? (Eyeroll). Also; given launch costs, there are likely to be pressures to combine assets. So - who really wants tourists poking around the factory floor, even here? All that aside; someone has to be first - or we're not getting off this rock! Quote Link to comment Share on other sites More sharing options...

You'd think they'd want 2 atm (1 over ambient). Maybe a typo? (I'll admit I didn't do the math when I saw it, and I don't think in PSI) Quote Link to comment Share on other sites More sharing options...
Piscator Posted Thursday at 05:19 PM Share Posted Thursday at 05:19 PM It's above the cabin pressure in airliners, so I guess it would be sufficient. There's not really a need to use the ISS standard, is there? Quote Link to comment Share on other sites More sharing options...

All that aside; someone has to be first - or we're not getting off this rock! Agree, now most research its easier. NASA states it want to rent in on an commercial space station, they pay for hotel services and to dock multiple labs to the station. That is the obvious money tourists is an bonus, and the long term crew would enjoy spending dinners with very rich space geeks. Quote Link to comment Share on other sites More sharing options...
