Two International Space Station (ISS) managers are
taking on new positions in the program. Michael T. Suffredini
has been named ISS deputy program manager at NASA’s Johnson
Space Center in Houston. Mark S. Geyer will replace
Suffredini as mission operations integration manager for the
ISS Program. After a transition period, the assignments
formally begin in August.

“I am fortunate to have these two experienced managers on the
ISS team,” said Bill Gerstenmaier, ISS Program Manager. “I
look forward to working with them in their new roles and
continuing successful operation of the ISS Program and
vehicle.”

As the ISS Deputy Manager, Suffredini is responsible for the
day-to-day management, development, integration and
operations of the orbiting research laboratory. Suffredini is
replacing Col. Charles J. Precourt, who recently was named
the program director of the Crew Exploration Vehicle.

In previous positions at NASA, Suffredini managed ISS
Operations Integration, ISS Vehicle Development and the ISS
Payloads Office, and served as deputy manager of the ISS
Business Management Office. He was instrumental in the
startup of on-orbit operations and sustaining engineering in
addition to launching the ISS research program. Suffredini
joined NASA in January 1989 and holds a bachelor’s degree in
aerospace engineering from the University of Texas, Austin.

As the new manager of ISS Operations Integration, Geyer will
serve as the Chair of the ISS Mission Management Team and
will be responsible for coordinating and integrating critical
activities associated with the performance of real-time ISS
missions.

Before joining NASA in 1990, Geyer worked at the Lockheed
Missiles and Space Corp. in Sunnyvale, Calif., as a systems
engineer supporting the Lunar and Mars Exploration Office. He
joined the ISS Program in 1994, most recently serving as
manager of the Program Integration Office. Other assignments
included lead of the System Integration and Analysis Office,
Increment 0 Manager and manager for the Russian Elements
within the ISS Program. Geyer holds a master’s degree in
engineering from Purdue University, West Lafayette, Ind.
