I know nothing about any of this so take what I say with a grain of salt. That said, let's go over some of the history of Mike Griffin. I went to that article looking for the answer to the question of whether he was much involved with the clusterfuck that was the Shuttle program, which kept killing astronauts through its transparently-lax approach to safety. The answer turned out to be no, which is to his credit. But, what did he do?
[On] June 1, 2007, on NPR News' Morning Edition, Griffin said: "I have no doubt that global—that a trend of global warming exists. I am not sure that it is fair to say that it is a problem we must wrestle with. To assume that it is a problem is to assume that the state of Earth's climate today is the optimal climate, the best climate that we could have or ever have had and that we need to take steps to make sure that it doesn't change. First of all, I don't think it's within the power of human beings to assure that the climate does not change, as millions of years of history have shown, and second of all, I guess I would ask which human beings -where and when-are to be accorded the privilege of deciding that this particular climate that we have right here today, right now is the best climate for all other human beings. I think that's a rather arrogant position for people to take."
Griffin approved the launch of Space Shuttle Discovery for July 2006 to perform the second return-to-flight mission, overriding the NASA Chief Safety and Mission Assurance Officer, Bryan O'Connor. Although O'Connor said there were still unresolved concerns that foam insulation could break off of external fuel tank and damage the orbiter, Griffin characterized the risk as acceptable, arguing that it would be better to test one change at a time.
Griffin has been criticized by space research organizations such as NASA Ames Research Center life sciences group for shifting portions of NASA's budget from science to human spaceflight. Griffin had stated that he would not shift "one thin dime" of funding from science to human spaceflight, but less than six months later, in February 2006, after NASA Constellation funding did not reach requested levels, NASA revealed a budget that reduced space research funding by about 25%, including indefinite deferrals of planned programs such as the Jupiter Icy Moons Orbiter, the Terrestrial Planet Finder, and the Space Interferometry Mission. The logic was that funding Project Constellation, a presidentially mandated program, was the top priority of the space agency.
Subsequent to the findings of the Augustine Committee in 2009 that the Constellation Program could not be executed without substantial increases in funding, on February 1, 2010, President Barack Obama proposed to cancel the program.
