Approaching the new reality

I'm very pleased to be here and to have this opportunity to discuss with you what I view as the current challenges in space science. Today, NASA finds itself at a major crossroads. We are in the process of moving from one era in our existence into another. As we continue to launch important science missions, we are simultaneously changing the way we do business, in a very fundamental way. We are again focusing on more frequent access to space through smaller, less costly missions. We are again focusing on NASA's role as a source of technological advancement within the U.S. economy. And we are returning to the leaner, more flexible approach to managing our projects. In short, NASA has embarked on a new journey, and a challenging journey it will be.
