NASA's Role in International Affairs, Center for Strategic & International Studies, 26 April 2016 (Video)
"42:20: Q: When are we going to get to Mars? What is the time line?
Bolden: "2030s. As I said before the was no plan. And some people today contest our plan - but we have one. And a plan needs to at least have a definite date in which you're gonna do something. Because the President said so, for one thing."
Keith's note: OK Charlie. You have a plan to send humans to Mars? Post your plan online. Oh wait: you can't - because there is no plan.
NASA Begins Its Journey To Nowhere, earlier post
"No one with even a shred of fiscal accumen will tell you that a multi-decade program to send humans to Mars - as is typically done by NASA (delays, overruns, and PR hype) - is going to be done "within current budget levels, with modest increases aligned to economic growth." This is just back peddling NASA PR mumbo jumbo designed to try and make it seem that Lightfoot said something other than what he actually said."
