On October 12, 1984, President Ronald Reagan issued Executive Order 12490 that commissioned a panel of experts to investigate and evaluate the future of the national space program. President Ronald Reagan appointed Dr. Paine to be the chairman of this investigation. Rather than naming the commission after himself, as is customary, he chose instead to name it "The National Commission on Space". Members of the 15-member commission included Dr. Luis Alvarez (a winner of the Nobel Prize in Physics), Neil Armstrong (NASA astronaut and the first man on the Moon), Dr. Gerard K. O'Neill (American physicist and space activist), Dr. Kathryn D. Sullivan (Space Shuttle astronaut and first American woman to walk in space), Dr. Jeane Kirkpatrick (political scientist and former United States Ambassador to the United Nations) and Brigadier General Charles E. "Chuck" Yeager (rocket plane pilot and first man to break the sound barrier).
