Abstract

The National Aeronautics and Space Administration's New Millennium Program (NMP) is a space flight technology demonstration program that will validate the technologies needed to carry out the Earth and space science missions NASA envisions for the 21(sup st) century. The program is employing an innovative decision-making process to select the specific technologies that will be flight validated. First, NMP has articulated NASA's vision of science exploration for the next century, then it has defined the capabilities needed to execute that vision, and finally it will select and demonstrate the revolutionary technologies that provide those capabilities, thus enabling the science vision.
