In the new millennium, NASA will probe deeper into space, will search for ‘blue’ planets and life in the universe, will send humans and robots to other planets and beyond, and will bring back space knowledge to enhance quality of life on earth. For the microgravity fundamental physics program to be vital and relevant, it must contribute to this overall endeavor. NASA's Microgravity Fundamental Physics Program has been designed to serve these bigger goals at the onset of the new millennium.
