In part 2 of our series on the evolution of NASA's Journey to Mars, Michael Griffin gives the Constellation moon program a new look in an attempt to shorten America's International Space Station access gap after the space shuttles retire. But by 2009, the program is behind schedule and over budget.

Science in America depends on federal funding, yet many young scientists don't understand how the U.S. government decides to spend its money on science, nor are they encouraged to use their new degrees to advise the process. This is changing with support from the American Association for the Advancement of Science.
