Last week, NASA Administrator Charles Bolden testified before the Senate Subcommittee responsible for NASA's budget. In response to questions about the funding of Mars rover missions, The Planetary Society blog reported that Bolden stated the following:

This is an interesting statement and sentiment, and it's one that I've wrestled with myself for several years. The question really boils down to this: Should NASA continue to fund proven missions well past their design lifetime that are still successfully operating, or should they "pull the plug" and move the funding (that they never originally budgeted for in the first place) to some other project, one that uses technology a decade newer? And, if funding is pulled, will it spark a new conspiracy?

Here is a behind the scenes look at your tax dollars at work for federal research grants and the problems that arise when non-experts have a go at the process.
