I think it's shameful that the US didn't replace the Shuttle program before it was discontinued.

 

 

THIS, they knew how long the shuttles were good for.  They should have replaced the shuttles when they had the money.

Retaliation over the Ukraine sanctions, which are startimg to hurt.

This has been brewing for some time anyhow. They'be threatened to discontinue RD-180 sales to the US before, and they have endlessly delayed launching several new modules to ISS so they can use them in a new Russia-only military space station.

They may try to disconnect part of the Russian section of ISS for their new station, leaving ISS with no propulsion system with which to reboost when needed.

To continue using ISS the other partners would have to replace the missing capabilities, or let it burn up over the Pacific on reentry.

An alternative would be to let that happen, then transfer ISS National Laboratory activities to a commercial station, most likely built by Bigelow Aerospace and SpaceX who have a partnership.

2 Bigelow BA-330 modules would be slightly smaller than ISS and able to handle a crew of 6. ONE BA-2100 Olympus module would be almost 2x the volume of ISS and able to handle a crew of 12. Add modules as needed, tinker toy style.

No I am not Russian but the photos read "ours is bigger than yours". And this is what is going on with Ukraine right now. Ukrainians want to be Russian and by the looks of it the entire country might vote 100% pro-Russia but the US have to have their way to look strong in the eyes of the "allies".

Welcome to the new cold war...

 

Hot or cold, war drives technological advances so... not really a -bad- thing in this case! :p

Those station modules are by a private company who has been developing the tech since 2000 using private funds, long before the current problems. Also, NASA has been talking about using private space stations after ISS for several years.

This just improves the business case for both.

That these would be larger is due to the fact that Bigelow's polymer based technology, which is far cheaper to deploy than ISS's tin cans, gets cheaper per cubic meter as you make them larger. A side effect of Geometry 101.

Why go to the expensive time / effort to get cans docked into orbit again, just build on the moon :D

geometry 101 also says that by simply blowing them bigger the only thing you achieve is getting more useless space for floating around, actual usable space doesn't increase as much as the volume you need to fill with breathable atmosphere. unless you also in subsequence transport up a lot of latticework and modular floors and walls and cabling to build usable space inside them.

Can't do zero g research on the moon.

The Bigelow modules have a large central core, perfect for logistics and hardware as well as stiffenting the structure and connecting the docking bulkheads, and the outer walls are likewise usable for equipment mounts etc. In short, there's not as much empty space as you're presuming. The BA-2100 is also divided into several decks, further increasing useful "wall space" and minimizing dead air space.

All open spaces can be divided into cubicles such as a radiation shelter for solar events, a galley, bathroom, sleeping bays etc.

Some versions of BA-2100 are divided and have a huge airlock to allow bringing crewed spacecraft inside for servicing.
