Houston, Texas, May 29, 2003 – SPACEHAB, Incorporated (NASDAQ/NMS: SPAB), a leading
provider of commercial space services, today announced changes to the Company’s Board of Directors,
including the appointment of Dr. Fritz-Stefan Graul.

Dr. Graul is the Director of Orbital Infrastructure & Operations and Reusable Systems for Astrium,
Europe’s leading aerospace company. He is responsible for overseeing strategic planning, business
development, and operations. Dr. Graul also manages all contractual and business dealings between
SPACEHAB and Astrium Space Infrastructure and has been instrumental in forging a strategic alliance
that has proven beneficial to both organizations and the aerospace industry as a whole.

Dr. Graul replaces former Board member, Josef Kind, who held a seat on the SPACEHAB Board of
Directors since October 1999. Due to time constraints associated with his role as President of the Space
Transportation Division of the European Aeronautics Defense and Space Company (EADS), Astrium’s
parent company, Mr. Kind has decided to relinquish his Board position. As a holder of SPACEHAB
Series B Senior Convertible Preferred Stock, Astrium may elect one member to the Company’s Board of
Directors.

“We welcome the opportunity to benefit from Dr. Graul’s diverse talent and experience,” said
SPACEHAB Chairman of the Board, Dr. Shelley A. Harrison. “We appreciate Mr. Kind’s numerous
years of dedicated service, helping SPACEHAB in its space access and commercialization initiatives,”
concluded Dr. Harrison.

In addition, Mr. Hironori Aihara, Senior Executive Vice President and Chief Executive Officer of
Mitsubishi International Corporation, has resigned from SPACEHAB’s Board of Directors after 11 years
of devoted service. He announced his retirement from Mitsubishi earlier this month and plans to return to
Japan. The Board position previously held by Mr. Aihara will remain vacant until the next annual
shareholders meeting.
