I wonder if the space station planned by Axiom has to be complied with, or if Bigalow, Sierra Nevada etc components can be incorporated (making a different future station to the one planned by Axiom). The new station is to be designed learning from the mistakes learned from the ISS and to be user friendly for private sector commercialisation. I am pleased to see that the U.S. Government seem favourable to keeping the ISS going till 2030 and that it's replacement is already in progress.
