Leadership
The administrator is the highest-ranking NASA official and serves as the senior space science adviser to the President of the United States. The administration is located at NASA Headquarters in Washington, DC and provides overall guidance and direction to the agency.
The first Administrator was Dr. T. Keith Glennan; during his term he brought together the disparate projects in space development research in the US.
Some administrators like Richard H. Truly (administrator 1989–1992) have been astronauts themselves. Among others he piloted Space Shuttle Columbia in 1981 on its second flight and later supervised the rebuilding of the shuttle program after the disaster of Challenger in 1986
