NASA Is Already Considering Retirement of SLS (Update)

NASA will retire its new mega-rocket if SpaceX or Blue Origin can safely launch its own powerful rockets, Business Insider

"I think our view is that if those commercial capabilities come online, we will eventually retire the government system, and just move to a buying launch capacity on those [rockets]," Stephen Jurczyk, NASA's associate administrator, told Business Insider at The Economist Space Summit on November 1. However, NASA may soon find itself in a strange position, since the two private launch systems may beat SLS back to the moon -- and one might be the first to send people to Mars. ... "We haven't really engaged SpaceX on how we'd work together on BFR, and eventually get to a Mars mission -- yet," Jurczyk said of NASA's leadership. "My guess is that it's coming."

Keith's note: Dave Mosher is a solid reporter so I am confident he reported what was said. Either Steve Jurczyk misspoke or was mistaken. Either way the boss just cleared this up. Twitter is handy that way.
