Are the Days of NASA's Science Flagship Missions Over?, Space Policy Online (last week)
"NASA Administrator Charlie Bolden had a tough message for the space science community today - forget about flagship missions, they're not affordable today. At the very same time on Capitol Hill, however, the chairman of one of NASA's key committees was expressing enthusiasm about a mission to Europa - unquestionably a flagship mission. The disconnect could not be more stark. Flagship missions are NASA's most expensive (over $1 billion) and risky space science missions, but offer exceptional scientific payoff."
"NASA remains committed to planning, launching and operating flagship missions that meet the challenging objectives of our science, technology and aeronautics communities as identified through decadal surveys, advisory groups, the Administration and Congress. We are dedicated to pursuing the most cost-effective ways to accomplish this goal in order to provide balance with an increased cadence of missions that vary in size, destination and complexity."
