Is Privatizing ISS A Smart Thing To Do?

Astronaut: Trump's plan for the space station a huge mistake, op ed, Leroy Chiao, CNN

"What about privatizing the ISS? That idea is barely worth mentioning. The ISS was designed to operate with two big mission control centers, in Houston and Moscow. They each need standing armies of onsite engineers and technicians around the clock to monitor and send commands to the station. Estimates of the cost of launching spacecraft to the ISS vary, but they are certainly in the range of $100 million or more. Let's not even consider maintenance costs. Tell me with a straight face how a commercial entity is going to make money operating ISS? The Trump administration's thoughts to cancel ISS and send the savings to the moon is déjà vu. The actual savings will likely be again around 50% of the ISS program cost, and all we are likely to end up with is an inadequately funded moon program, as we have had for the last nine years. And no ISS, either. This path would likely leave us with nothing but a bare-bones spacecraft and rocket and no funding to go anywhere. Unless, of course, we decide to fly American astronauts on Chinese spacecraft to the coming Chinese space station. This would be a national travesty. What we need is a real commitment to maintain US leadership in human spaceflight."
