History

The first administrator of NASA was Dr. T. Keith Glennan; during his term he brought together the disparate projects in space development research in the US.^[3] Daniel Goldin held the post for the longest term (nearly 10 years), and is best known for pioneering the "faster, better, cheaper" approach to space programs.^[4] The only person to hold the post twice is James C. Fletcher, who returned to NASA following the Challenger disaster.^[5]

The current administrator is former senator and astronaut Bill Nelson, who was nominated by President Joe Biden on March 19, 2021,^[6] confirmed by the Senate on April 29, and officially sworn in on May 3.^[7]
