Veteran astronaut and senior Space Shuttle manager Donald R. McMonagle has announced his departure
from NASA for a position in private industry effective Friday. McMonagle’s duties at the Kennedy Space
Center, FL, as Shuttle Manager of Launch Integration will be temporarily assumed by Bill Gerstenmaier,
Manager of Shuttle Program Integration at the Johnson Space Center, until a permanent replacement is
named.

“Don has given tremendous service to NASA and this country,” said Ron Dittemore, Space Shuttle Program
Manager. “His expertise, wisdom and contributions to the safe and successful exploration of space have
been invaluable. He will be greatly missed.”

McMonagle has served at the Kennedy Space Center as Manager of Launch Integration for the Space
Shuttle Program since 1997. His responsibilities included managing Shuttle launch preparations; overseeing
launch of the Shuttle; and ensuring the safe return of the Shuttle to KSC following landings at remote
locations. He also served as chairman of the Space Shuttle Mission Management Team for launch.

“The team that processes, launches and flies the Space Shuttle is composed of the most dedicated people
with whom I have ever worked, and I have been deeply honored to count myself among them,” McMonagle
said. “I am leaving NASA with the firm belief that the Space Shuttle today is safer than it has ever been. And
I’m confident that the Shuttle team is more firmly committed to achieving excellence in their job now than
ever before.”

McMonagle was selected as an astronaut by NASA in June 1987 and has flown on three Space Shuttle
missions, logging more than 605 hours in space. He flew as a mission specialist aboard Discovery on
mission STS-39 in April 1991; as pilot of Endeavour on STS-54 in January 1993; and commanded the crew
of Atlantis on STS-66 in November 1994. Prior to assuming his current position, McMonagle was named in
1996 to establish a new Extravehicular Activity Project Office at NASA responsible for managing the
resources, planning and execution of spacewalks in support of the Space Shuttle and International Space
Station.
