NASA's Centennial Challenges program promotes technical innovation through novel prize competitions. It is designed to tap the nation's ingenuity to make revolutionary advances to support the Vision for Space Exploration -- the plan to return humans to the moon, paving the way for journeys to Mars and beyond. The five prize competitions push the state-of-the-art in a wide range of capabilities and technologies.

"The Centennial Challenges program and our allied organizations are opening the starting gate for five competitions," said program manager Brant Sponberg. "We welcome new teams to the Challenges ? they are the lifeblood of the program and bring great excitement and innovation."

The Exploration Systems Mission Directorate manages the program. For more information about the Centennial Challenges Program and the five challenges on the Web, visit:
