Is NASA Building A Rocket They Can't Afford to Fly?

Little Love for Asteroid Retrieval Mission; Squyres Deeply Worried about SLS Launch Rate, Space Policy Online

"Another concern Squyres stressed is the low flight rate for the Space Launch System (SLS). "I'm deeply worried," he told Edwards, because no other human spaceflight system has had such a low anticipated launch rate. The first SLS launch is expected in 2017, the second in 2021, and then once every two years thereafter. SLS and the Orion spacecraft need to be adequately funded "to be proven out on a pace that really supports ... a safe pathway" to cis-lunar space, Squyres insisted. Cooke agreed. The flight rate is driven "totally" by funding, he said, and "they definitely need more funding ... starting with inflation." NASA's budget is currently projected to be flat, with no adjustment for inflation, which erodes buying power as the years pass."

Faster, NASA, Faster, opinion, Ed Lu, NY Times (2009)

"In the 12 years before I left NASA in 2007, we averaged about four space shuttle launchings per year. We had periods when the rate was even lower: in the late '90s, during the early construction phase of the International Space Station, and in 2003, in the wake of the space shuttle Columbia disaster. I saw firsthand the harm that low launching rates do to innovation. With precious few flights, every available opportunity to test new equipment or run scientific investigations was filled for years into the future, and this discouraged engineers from trying out new ideas. Without actual flight test data on, for example, prototypes for new life-support equipment, management was forced to substitute analysis for real engineering experience."
