Five years later, what does it think about SLS?
The country, with NASA’s budget, simply can’t afford to build a large rocket that will fly infrequently and cost as much as $2-$3 billion a year to maintain, Greason said.
“It’s hard for me, I personally haven’t been able to find a scenario in which a government funded and operated launch system, for which the government is the only customer, is a rational approach given the current budgets.
“Is that because I’m against big rockets? Of course not. But maintaining rocket production lines is a very expensive proposition. Trying to open another production line for a rocket that has almost no customers is a difficult thing for me to explain. The one argument I have heard that, if it were true, I would buy, is that there are no other ways to explore. I would buy that, but I don’t think it’s true.”
It’s not true.
