Sean O'Keefe (born January 27, 1956) is a former Administrator of NASA, leading the space agency from December 2001 to February 2005. His tenure was marked by a mix of triumph and tragedy, ranging from the tremendous success of the Mars Exploration Rovers to the disintegration of the Space Shuttle Columbia.
On February 21, 2005, after resigning from NASA, O'Keefe replaced Mark Emmert as chancellor of Louisiana State University. O'Keefe is also a former member of the board of directors of DuPont. He resigned from LSU on January 16, 2008 after rumors reporting that LSU System President John V. Lombardi told him to find a new job.
Asteroid 78905 Seanokeefe was named after him in honor of his time as NASA Administrator.
Sean O'Keefe came to NASA with a background as a former Secretary of the Navy and Deputy Director of OMB. As was the case with a well-respected prior NASA Administrator, James Webb, O'Keefe had no formal training in science or engineering. As with Webb, his deputy and senior staff were aeronautics and space experts.
Sean O'Keefe's most controversial decision occurred in February 2004, when he attempted to cancel an upcoming mission by the Space Shuttle to service the aging Hubble Space Telescope. O'Keefe claimed that, in light of the Space Shuttle Columbia disaster, the mission would be too risky, especially since if the shuttle was damaged while visiting the Hubble, the shuttle would not have enough fuel to dock with the space station as a "safe haven." While supported by members of the Columbia Accident Investigation Board (CAIB) this decision was assailed by numerous astronomers, who felt that the Hubble telescope was valuable enough to merit the risk. An earlier, arguably far more controversial choice, was O'Keefe's decision to not expend the funds necessary to re-task a satellite to scan the space shuttle Columbia for damages. The resultant monetary "savings" proved to be vastly more expensive with the loss of the shuttle Columbia and the seven Astronauts.
In late October 2006 O'Keefe's successor, Mike Griffin, reversed the decision, regarding the mission to Hubble, after several years of study. Griffin had previously expressed a willingness to send up a repair mission and to launch the Discovery on July 13, 2005 to the International Space Station (see STS-114). One of Griffin's first actions as NASA administrator was to organize a group at Goddard Space Flight Center to study and prepare for a potential Hubble maintenance mission with the Shuttle. The final Hubble mission, STS-125 is scheduled for October 10, 2008. It will service Hubble's gyroscopes and install two new instruments: the Cosmic Origins Spectrograph and the Wide Field Camera 3.
In 2004, O'Keefe drew some criticism for openly campaigning for a gubernatorial candidate (Riley, AL-R) and a member of Congress (O'Keefe's commercial flight was grounded due to weather and he never attended the event). He defended his action by saying that he was campaigning as a private citizen.
O'Keefe responded to President Bush's Vision for Exploration by hiring retired Navy Admiral Craig E. Steidle who had previously led development of the Joint Strike Fighter (JSF) as an associate administrator in charge of a new office - Exploration Systems Mission Directorate (ESMD). A mission architecture for lunar exploration was developed based on four launches of medium-lift vehicles and four space rendezvous per mission. This mission architecture was immediately scrapped by Michael D. Griffin upon his arrival at NASA. NASA started over with the Exploration Systems Architecture Study (ESAS), sixteen months after the Vision for Space Exploration (VSE) had been announced by President Bush. That architecture led to the Ares 1 and Ares V launch vehicles and the Orion Crew Exploration vehicle which are now under development by NASA.
There were allegations of misuse of government airplanes that were brought up by government investigators at the tail end of his tenure at NASA.
Prior to that, O'Keefe served as acting United States Secretary of the Navy from 1992–1993 under President George H. W. Bush. Prior to joining the administration of George W. Bush, O'Keefe was the Louis A. Bantle Professor of Business and Government Policy, an endowed chair at the Syracuse University Maxwell School of Citizenship and Public Affairs. He was also a Professor of Business Administration and Assistant to the Senior Vice President for Research and Dean of the Graduate School at Pennsylvania State University.
Before serving as acting Secretary of the Navy, O'Keefe had been Comptroller and Chief Financial Officer of the Department of Defense since 1989. Before joining the Department of Defense, he served on the United States Senate Committee on Appropriations staff for eight years, and was Staff Director of the Defense Appropriations Subcommittee.
O'Keefe lightly discussed his membership in the exclusive Bohemian Club to the LSU student newspaper The Daily Reveille. As a member of the Wayside Log camp, O'Keefe traveled during July 2005, to visit the famous Bohemian Grove grounds near San Francisco, California.
