Good the iss is a hinderence, it swallows up vast amounts of money. Which could be going towards a moon base or deep space gateway.
It's also very old and is taking ever more time to repair.
Privatising it is pointless, a due to repair time and b due to Bigelow expandable habitats, 2 of their large ones gives you more pressurised volume than the iss.
Iss needs to have longer duration missions. Like 2 years. They also need to test new equipment. Really should send up the centrifugal beds and see how they work,as well as modern co2 scrubbers.test the tech for the first gen private stations.
NASA can then buy a Bigelow station and turn it into the deep space network.
And rivatisation in space works extremely well.becuase unfortunately Congress dictate NASA what to do and why the sls has allready cost over 15bn compared to less than 1bn for falcon heavy. Same with flight costs have around 100m, SLS being close to 1bn we launch.
NASA should build future stuff outside of what privatte companies can do. Not only are they not doing that, they spend many more times the money to develope stuff private industry surpasses.
Oh and they need to test a new toilet.
