   Yes, the physics are worse, and yes, the economics are worse, but data centers in space have the crucial advantage that they are out of range of the molotov-throwing arm of Joe Public (recently unemployed).

      Similarly to Starlink , which was hyped as a low codt alternative for marginalised people/areas and sucked in enormous subsidies to that end. While being more or less a proof of concept for a military command and control network , thats the same way this should be looked at.Especially with data centers being vulnerable on ground, coupled with the ability to reposition the space based units to be 'closer to the action' as it were.

      So bottom line a proof of concept for DARPA funds and eventual inegration into the military command and control nodes.

         I dunno, won't a satellite be _more_ vulnerable in space? There is not anti-missile tech in space.

         I suppose it is about being out of reach of cheap drones?

            It's really about bandwidth and availability - US satcom systems were really struggling, and the only truly global (Iridium) was quite low bandwidth. Starlink is essentially "Iridium with newer tech and mass production" and IIRC DoD through various fronts put quite a lot of early financing to make it a thing, even if later the networks were supposedly disaggregated (would make sense to start building separate one once PoC was proven)

               DoD financing for Starlink was a long term game to create pLEO sensing capabilities: initially GMTI, then AMTI.

               Both of which give the US military more persistent (revisit delay near zero because number of assets) and survivable (number of assets + LEO debris characteristics + cattle vs pets) ISTAR.

               And an advantage in persistent ISTAR is a key enabler of the way the US military is aiming to fight a peer state adversary.

               I'd be fascinated to dig into the contracts, but at 10,000' it's DoD offloading the bulk of the development cost onto NASA and the public (which in both cases, still gets good value for money).

                  That's a lot of acronyms. You might be saying something interesting, but no one outside of that particular area of expertise will understand it.

                        Looked back on this and correction: proliferated Low Earth Orbit

                        Newer acronym, but apparently en vogue with the "How do we maintain a critical military space capability against someone who can shoot down exquisite satellites?" crowd.
