NASA has extended a primary contract for the International
Space Station for On-Orbit Acceptance and Vehicle Sustaining
services to The Boeing Company of Houston.

Work under the contract extension will provide delivery, on-
orbit acceptance, sustaining engineering and postproduction
support for hardware and software of the U.S. segment of the
Station, and for common hardware and software provided to the
International Partners and Participants. The work also will
include providing management of the majority of Space Station
subsystems and specialty engineering disciplines such as
materials, electrical parts, environments and electromagnetic

The basic period of the cost-plus-award-fee contract extension
is two years and nine months with an estimated value as much as
$1 billion. Four six-month options are available and, if fully
exercised, could bring the total contract value to $1.62
billion. Work on the contract will be performed at NASA’s
Johnson Space Center in Houston, NASA’s Kennedy Space Center in
Cape Canaveral, Fla., NASA’s Marshall Space Flight Center in
Huntsville, Ala., as well as in other locations inside and
outside of the United States.

This extension was awarded as part of a restructuring of
Station contracts. The goal is to consolidate work, increase
efficiency, increase accountability, and transition the
program’s contract strategy from development and construction
of hardware to orbital operations. Information about Space
Station contract strategy is available on the Internet at:
